Chapter 2 – Overview
2.1 Introduction
The Merchant e-Solutions (MeS) Payment Gateway Application Programming Interface
(API) utilizes the Internet to provide a simple and secure method of processing credit card
payments. By sending an HTTPS POST with minimal transaction information to the
payment gateway, a merchant can avoid the complex transmission protocols and
message formats unique to the credit card payment industry networks. MeS not only
simplifies the procedure, but manages the ongoing process of change resulting from
credit card association requirement updates.

2.2 Settlement to Bank
The MeS Payment Gateway accepts a request and returns a response, allowing a limited
set of administrative actions. Each day, at a time chosen by the merchant, all
transactions that have been approved are marked for capture and automatically settled.
The settlement process results in funding to the merchant’s bank account.
The client is responsible for all development and security required to post the request and
handle the response. This includes maintaining compliance with all PCI regulations.

Chapter 3 – Credit Card Processing
3.1 Introduction
A successful payment transaction consists of two elements: authorization and capture.
The issuer of the credit card provides the authorization based on a number of factors
including availability of credit and status of the account (card not reported stolen, for
example). The response provided by the issuer includes an approval acknowledgement
or a decline code, along with additional information such as billing address verification
and/or cardholder validation value match results. When an approval is issued on a credit
card transaction, that dollar amount is removed from the amount of available credit on
that account for a given timeframe (determined by the issuing bank).
Capturing a transaction, or marking an authorized transaction for capture, is required for
that transaction to be settled, or submitted for final processing that results in a charge to
the cardholder and a credit to the merchant.
The distinction between authorization and capture exists to accommodate differing
processing requirements. For example, some merchants may only need to do a single
sale transaction in which an authorized transaction is automatically marked for capture.
Another merchant may need to obtain an approval but, because an item might not be
available for shipment that day, or the final billing amount might differ from the authorized
amount, may not want the payment to be included with the next settlement. This latter
merchant would want to handle the authorization and the capture in two steps.
Best Practice: There should be a 1 to 1 relationship between an authorization and a
settlement (capture). To settle an amount larger than the authorization a new
authorization for the full amount should be requested, then void the original authorization
to reverse the hold on funds. The only exception are industries that allow for a gratuity
and are listed below.
Best Practice: A settlement should occur within 7 calendar days of the authorization. If
the delay is more than 7 days, the merchant should obtain a new authorization and void
the original.
Whether a transaction is authorized and captured all-at-once, or in sequential steps, is
the result of the Transaction Type submitted in the authorization request. The MeS
Payment Gateway API accepts the following Transaction Types:
Transaction Type
Sale
Pre-Authorization
Description
If the transaction receives an approval, it
will be automatically marked for settlement
at the same time.
The transaction will be authorized but not
marked for capture. To complete a PreAuthorization, a Settle Pre-Authorization
transaction must be performed to mark the
transaction for capture. Once marked for
capture, a transaction will be included in
the next scheduled settlement batch.
Comments
Settling a transaction seven
days or more from the
approval date will result in a
downgrade to the Interchange
levels, resulting in higher
processing costs. Settling a
transaction beyond seven
days from the date of approval
also increases the risk of a
chargeback. No transaction
should be settled more than
twenty-eight days after the

Transaction Type
Settle PreAuthorization
Description
A Settle Pre-Authorization marks the
matching Pre-Authorization transaction for
capture.
Best Practice: There should be at least 15
seconds between a Pre-Authorization and
a Settle Pre-Authorization request.
Multi-Settle
This function is used by merchants that
initially process a transaction but settle for
less, want to process another sale but no
longer have the card credentials. This is
most typically used in a scenario where
items are on back order.
This function should NOT be used as a
way to facilitate recurring billing. The
store card function should be used for
recurring.
Multi-Settle transactions may not be
submitted for transactions older than 30
days.
Multi-Settle requires initial authorization
and settlement to be written to the
database to function properly. It is not
intended for the user to send concurrent
settlement requests.
Re-Auth (of a
declined
transaction)
This transaction is typically used when a
transaction is declined and the merchant
no longer has the card account
information (particularly the full account
number) in order to resubmit the
transaction.
Declines older than 30 days may not be
re-authorized.
Void
A Void request should only be processed
for a Pre-Authorization transaction.
Voiding a Sale should be done with a
Refund transaction. Voiding a PreAuthorization will initiate an auth-reversal.
Comments
approval date.
If the settled amount is less
than the original request a
partial auth-reversal will be
issued. Requests to settle
amounts greater than the
authorization will be ignored
unless the merchant MCC
allows for tip processing.
These are: 5812 - Restaurants
5813 - Bars and Taverns
5814 - Fast Food Restaurants
4121 - Taxicabs & Limousines
7230 - Hair Salons
7298 - Health & Beauty Spas.
Each new request is
considered a new sale,
therefore there is no cap on
the amount of sale. All
transactions are submitted
with the transaction type “S”
and the original transaction ID.
Each new request will receive
a new Transaction ID.
This function is available for
both USD and International,
but not available for FX
transactions.
This function is not intended
and should not be used for
repeated authorization
attempts. It is recommended
that after a decline, the
merchant either contact the
customer for a recommended
day to re-submit, or wait a few
days prior to resubmission.
This function is available for
USD transactions only, full
card numbers are not stored in
MeS database when declined.
A Void will generate an authreversal, which, depending on
the bank, may release the
amount held by the
authorization.
Best Practice: A Void transaction should
be restricted to Pre-Authorization
transactions. Once a Settlement has been

performed on a Pre-Authorization it is best
handled with a Refund transaction.
Refund
A Refund request looks for the
Transaction ID of the originating
transaction. If that transaction has not yet
been settled, it will void the transaction
from the batch. If that transaction has
been settled, it will issue a credit
transaction.
Partial Refunds: To issue a partial refund,
provide the transaction amount parameter
in the request. Partial refund amount must
be less than or equal to the original
transaction amount.
A refund to the cardholder.
Credit
Best Practice: Whenever possible a refund
should be processed rather than a credit.
A refund is a safer transaction because it
references a prior transaction and cannot
exceed the amount of the original sale.
Store card
Store card number. The transaction_id
returned by the store request can be used
in subsequent requests via the card_id
parameter.
Delete Store card
The function will delete a transaction from
the Gateway that was previously stored
using the store card feature
These transactions will be settled using
the authorization code provided by the
merchant in the request.
Offline
Verification Only
This transaction is non-monetary in nature
and is used to verify the card number and
billing address of a cardholder. This
service is most fully supported by Visa
For American Express and Discover this
service will validate address and zip only,
The word "Void", "Adjustment"
or "Credit" will be included in
the response message to
indicate the result of the
action.
Transactions may be refunded
only once if submitted for the
full amount of the original
transaction.
Multiple refunds are permitted
for a single sale transaction up
to but not over the original sale
amount.
A credit transaction does not
attempt to match to a prior
settled or unsettled
transaction. A credit is a
stand-alone transaction. The
ability to do a credit must be
enabled in the Merchant eSolutions MeS profile.
Enables user to safely store
cardholder card number on
MeS secured servers for
processing future transactions.
This can be performed
independently or in
conjunction with a pre-auth or
sale transaction.
Offline transactions typically
result when an authorization
attempt results in a “Call”
response, or when
authorization codes are
obtained by phone because of
a technical problem.
Transactions submitted using
this transaction code will be
downgraded to lower
Interchange levels.
Offline transactions are not
permitted for International
transactions.
For this transaction to be
successful and reach the
issuer for true validation both
street address and zip code
must be submitted. If no
address information or zip only
is submitted the response will

it will not provide any status on the
account (open, closed, etc). In addition,
the card verification value is not validated.
MasterCard supports an AVS only
transaction with a zero amount and will
verify only address match and not the
status of the card.
Inquiry
Batch Close
This function may be used to inquire about
a previously submitted transaction.
Typically used if the system times out and
does not provide a response back to the
originator. If found all original response
fields will be returned, if the transaction is
not located a message will be returned
indicating it was not found. In addition, a
retry_count will be included to indicate the
number of inquiries on a particular
transaction.
Allows a user to initiate a batch close via
the API.
Comments
not be successfully processed.
In addition, an amount of
$0.00 should be submitted.
Verification Only is not
permitted for International
transactions.
This request is only valid
within 48 hours of the original
request. In order to use this
function, a retry ID must be
submitted with every
transaction, this is the
identifier used to perform this
function.
Primarily designed for POS
applications that typically have
a close function built in.
Typically these will be POS
terminals.
In addition to transaction types, there are transaction elements that may need to be
considered when processing transactions.
3.2 Transaction Method
Transactions can be accepted in the following ways:




Card-Present
Non-Card-Present Mail/Telephone Order (MOTO)
E-Commerce Transaction
Recurring Billing
The credit card associations require that a transaction be identified by the method of
acceptance. This is done primarily through the moto_ecommerce_ind field, although
there are additional field and security requirements that correspond with each acceptance
method.
A card-present transaction is one where the magnetic card stripe is read by an electronic
device and sent with the authorization request. The cardholder is presented with a paper
receipt to sign which the merchant retains, and is provided with a copy for their records. In
the event that the card stripe is damaged and cannot be read, the transaction can be
hand-keyed at the point-of-sale.
A higher transaction fee may be incurred when a card-present transaction is hand-keyed.
Card track data (data from the magnetic stripe read) can never be stored by a merchant.
Payment Gateway v4.10
©2013 Merchant e-Solutions, Inc.
10
Non card-present MOTO indicators include: a onetime mail/telephone order (MOTO), a
recurring transaction, and an installment payment.
A recurring charge has no defined number of payments; an installment charge has a set
number of charges, such as 7 payments of $19.99.
An e-commerce transaction is a sale that is conducted on the Internet. A secure
transaction uses Secure Socket Layers (SSL) with encryption strength of at least 128-bit.
No e-commerce transaction should ever be processed in a non-secure manner.
Note: The MeS API defaults transactions with an e-commerce indicator of 7. Only
transactions that fall into a different category need to include this indicator.
3.3 Risk Management Tools
There are many tools available at the transaction level to help merchants manage risk
and reduce fraud when accepting non face-to-face credit card transactions. These include
standard tools such as Address Verification Service (AVS) and Cardholder Validation
Code. In addition, use of optional fields like Dynamic Descriptors may reduce cardholder
disputes that while not fraud related may improve overall processing. MeS also offers a
comprehensive risk and fraud management system called FraudDeflector.
3.3.1 Address Verification Service
Address Verification Service (AVS) is a tool to help merchants manage risk and reduce
fraud when accepting non face-to-face credit card transactions. By submitting the
cardholder’s billing address and zip code at the time of authorization, a comparison is
done against the billing information on file at the bank. A response is returned indicating a
full (address and zip) match, an address-only partial match, a zip code-only partial match,
or a response indicating AVS Results are not available (this could result from a number of
factors including an AVS system outage, the issuing bank not participating, etc.).
Best Practice: When initially accepting a card for payment, it is recommended to perform
a verification only transaction to verify the billing address and zip. This is a non-monetary
transaction that will not impact a customer’s “open to buy” on their card.
Performing AVS is a requirement with card-not-present transactions in order to qualify for
the optimal Interchange rate. Authorization requests that do not include the cardholder’s
billing address and zip will cost more to process.
While the credit card associations have mandated AVS be performed on non cardpresent transactions, there is no requirement based on result at this time. Deciding how
to handle transactions that receive responses other than a full match is based on a
merchant’s own risk tolerance.
The AVS result will not affect the transaction itself; if a transaction has received an
approval, it will process accordingly regardless of the AVS result. Merchants who may not
want to accept transactions with certain AVS results must take the appropriate action
depending on the type of transaction: a Pre-Authorization transaction should not be
converted to a Settle Pre-Authorization transaction until a merchant is comfortable with
the AVS discrepancy; a Sale transaction may need to be Voided before the next
scheduled settlement if the AVS result is deemed a significant risk.
Payment Gateway v4.10

3.3.2 Cardholder Validation
Card Validation Codes is another tool to help merchants manage risk and reduce fraud
when accepting non face-to-face credit card transactions. Under the generic “Card
Validation Code”, each card type has a unique name for the feature:




Visa: Card Verification Value 2 (CVV2)
MasterCard: Card Verification Code 2 (CVC2)
American Express: Card Identification Data (CID)
Discover: Card Identification Data (CID)
The Validation Code is a three-digit number that appears on the signature panel of Visa,
MasterCard and Discover cards. It usually appears on the back of the credit card, after
the account number printed on the signature panel. With America Express cards, it is a
four-digit number that appears above and at the end of the embossed card number on the
front of the card.
Submitting the Card Verification Code is not required by the credit card associations at
this time. Deciding whether or not to submit the Card Verification Code should be a
decision made by the merchant based on their own risk tolerance.
The Card Verification Code result, in most cases, will not affect the transaction itself; if a
transaction has received an approval, it will process accordingly regardless of the Card
Verification Code result. There are a few card issuing banks that will decline a transaction
based on a “No Match” Validation Code response.
Merchants who may not want to accept transactions with certain Card Verification Code
results must take the appropriate action depending on the type of transaction: a PreAuthorization transaction should not be converted to a Settle Pre-Authorization
transaction until a merchant is comfortable with the Card Verification Code discrepancy; a
Sale transaction may need to be Voided before the next scheduled settlement if the Card
Verification Code result is deemed a significant risk.
Card Verification Codes can never be saved by a merchant after a transaction has been
authorized.
3.3.3 Commercial and Purchase Card Extended Data
Commercial Cards and Level 2 Purchase Cards require additional or extended data as a
part of
the transaction. This data is included when the transaction is settled, and is used by the
card issuing bank to provide enhanced reporting to their cardholders.
Commercial and Level 2 Purchase Cards that are submitted do not include the additional
required fields may result in a processing fee that is higher than the normal cost for that
card category.
These fields may vary based on category and card type, but usually consist of one or
more of the following: Purchase Order Number (sometimes called Customer Code), Tax
Amount, and/or Tax Indicator.
If the appropriate extended data is not provided for these specific cards, the MeS
Payment Gateway will add those fields at the time of settlement. MeS will not overwrite
any data submitted by the merchant in the authorization request.
Payment Gateway v4.10

3.3.4 Dynamic Descriptors
In the event that a merchant needs to process some transactions with Doing Business As
(DBA) information different than the information on their merchant account, this
information can be included in the request message. Data in these fields will override the
profile DBA data.
Users of this feature must comply with association regulations. The first 3, 7, or 12 digits
must be static followed by an *. The remaining available characters may be unique. In
order to use this feature Payment Gateway Certification for Dynamic DBA must be
completed. The merchant profile will need to be enabled for this feature, and the static
prefix for the descriptor will be preset in the merchant profile. An example of a full
Dynamic Descriptor is provided in section 7.5.
3.3.5 Store Card
A request can be made to store cardholder data. This allows a merchant to process
transactions with the cardholder information at a later time by using an assigned
transaction ID, eliminating the need to store sensitive cardholder data. Store card may be
requested as an independent transaction or performed during a pre-authorization or sale
request.
3.3.6 FraudDeflector
The MeS FraudDeflector is an additional service offered to merchant’s using the MeS
Payment Gateway for processing. In addition to basic velocity checks, white and black
lists, the MeS FraudDeflector offers many external checks such as IP addresses and
country of issue.
Merchants that required detailed fraud analysis are encouraged to sign up for this
integrated service.
3.3.7 Settlement
Settlement happens automatically. If a transaction has been approved and marked for
capture, it will be included in the next settlement batch. Once a batch has settled, nothing
else (such as a void) can be done to that specific transaction. The cut off time should be
considered in regard to:


Completion of necessary actions such as corrections (Credits, Voids) or follow-up
actions (submitting an Offline transaction, converting a Pre-Authorization
transaction to a Settle Pre-Authorization transaction) that needs to be included in
the current batch.
Reconciliation of bank deposits.
The default batch close time is set to 09:00 pm PT but is configurable via the Payment
Gateway Back Office Administration. Batch close times set between 09:00 pm PT and
12:00 am PT are not guaranteed to process in that same day’s cycle.
3.3.8 Card Security Obligation
Compliance with Payment Card Industry (PCI) Data Security Standards (DSS) is required
of all merchants and service providers. This applies to all payment channels, including
retail (brick-and-mortar), mail/telephone order, and e-commerce.
Merchants

Merchants that are not yet PCI certified will receive follow up from the Merchant eSolutions PCI support team and will be provided tools and the assistance needed to
comply with PCI requirements.
All merchants should visit one or both of the following websites for comprehensive
information on the responsibilities and requirements for PCI compliance.
http://www.visa.com/cisp
https://www.pcisecuritystandards.org/
Third Party Resellers
Resellers must be PA-DSS certified prior to issuance of a certification letter by Merchant
e-Solutions.
If the reseller operates as both merchant and reseller they must comply with both PCI and
PA-DSS requirements. Because a merchant must be compliant with PCI requirements, it
is in their best interest to use software applications that follow best practices to facilitate
this compliance, the PA-DSS guide will provide the guidance necessary to ensure
applications and hardware meet these guidelines.
Resellers may visit the following website for additional information:

Chapter 4 – Back Office
The Payment Gateway Back Office provides the following functionality to supplement the
integrated processing:
Home provides a snapshot of transactions pending settlement, total pre-authorizations,
and one click access to the last settled batch. The back office home page also provides
important updates and industry new bulletins.
Administration allows the client to set the settlement time and designate transaction
acceptance based on AVS and Cardholder Verification responses.
Transaction processing is available for processing exception transactions manually when
the integrated processing is not an option. The client may process all transaction types
using a “virtual terminal”.
Batch Management allows for the management of unsettled transactions (marking as
settled or voiding), as well as the ability to view and print settled batches.

Chapter 5 – Testing and Certification Roadmap
5.1 Testing
In order to obtain an ID for testing, the certification request form must be submitted online
at http://resources.merchantesolutions.com/display/TPGPUB/Payment+Gateway+Certification+Request+Form.
Upon receipt of a completed form, the test ID will be emailed within 24 hours.

The certification request form is located at: http://resources.merchantesolutions.com/download/attachments/1411006/MeS+PG+Certification+Request+form+v1.1.doc?versi
on=1
Merchant e-Solutions will e-mail a document which contains important configuration
information, including Profile ID, merchant key and URL. These ID’s are set up for the
test/certification environment only.
Best Practice: It is important to use the test profile for testing to prevent billing for
authorizations obtained during testing. MeS will bill for all authorizations obtained using a
production profile even if the transactions are part of the testing cycle.
The MeS Certification Servers are available 24 x 7 for unattended testing. The
certification server is a replication of the Payment Gateway production servers and will
support testing for all available functionality. These transactions will all be processed as
test so there is no need to worry about live authorizations or potential settlement to a
cardholder account.
Test ID configuration will contain the following:
TPG Development PID for (Client Name)
PROPRIETARY SOFTWARE MERCHANT
CONFIGURATION INFORMATION
Certification DBA
Profile ID
Merchant Key
API Development URL
MeS PG Development TEST #
(unique profile id value)
(unique key value)
https://...
5.2 Certification
Once testing has been completed, a script will be provided that will test both record
formats and interchange qualification. These scripts will be customized for the client
based upon the record types identified on the Certification Request form.
Once the certification scripts have been reviewed and approved by the MeS Certification
team, a certification letter will be issued the Development Profile ID will be disabled.
The Production Configuration will be provided after the certification letter has been issued
and the client’s merchant number has been configured for the MeS Payment Gateway.
All transactions under this configuration will be live. It is important to remember when
installing the production ID’s that you ensure the URL is updated to route all requests to
the MeS Production Servers.

5.3 Test Card Numbers
The authorization process in the test environment is simulated. Any card may be used
without impacting the cardholder’s account as all responses are from a simulated
authorization system. MeS also suggests use of the test card numbers provided in the
table below:

5.5 CVV, CVC, CID Testing
This table will test CVV, CVC, and CID which is the 3 or 4 digit code printed on the back
of a card. This security feature assists merchants processing in a Card Not Present
environment and receiving a positive response ensures the likely hood that the
cardholder making the purchase is in physical possession of the card. Visa, MC, and
Discover encode a 3 digit value on the cards and American Express encodes either a 3 or
4 digit value. Defined input values will result in responses as described:

To obtain a partial authorization, submit any valid amount that will generate an approval
and the simulator will return 1/3 of the requested amount.
Balance Inquiry testing is not available for testing on the simulator but if requested and if
the issuer provides a balance it will be returned in production. In order to validate the
transaction processes include the balance inquiry request, the system will accept the
request but a value will not be returned.

Chapter 6 - Processing Interface
6.1 Communication Protocol
The MeS TPG API supports Hypertext Transfer Protocol using Secure Sockets Layer
(HTTPS). This provides a single-threaded process in which the originating server makes
an HTTPS request to the TPG and waits for MeS to return an HTTPS response. Although
HTTP is single-threaded, a single originating server can make multiple requests at once.
6.2 Batch Processing
Large batches may be processed using the Payment Gateway. Sale transactions
processed with a single Profile ID will run at a rate of approximately 7 transactions per
second (420 per minute or 25,200 per hour).
6.3 Security
HTTPS requests must be encrypted at 128-bit cipher strength. Upon receiving the HTTPS
request, the MeS API identifies and authenticates the request through two required fields:
the profile ID, which is a unique identifier assigned to each merchant, and a profile key,
which is a password linked to that profile ID. Once authenticated, the MeS Gateway
handles the transportation and storage of all cardholder data in accordance with Payment
Card Industry (PCI) requirements.

8.4 Adyen International Error Codes
Adyen responses will be one of 4 types: Approval, Refused, Error, and Exception:
 Approvals will indicate Authorised in the text and include an approval code.
 Refused will contain 000000 in the approval field and Refused – “detail” in the text
field. MeS will return a 350 Payment Gateway error code for refused
transactions. Ex: (Refused – Refused). If the acquirer returns a numeric refusal

code, MeS will send that code instead of a 350. Adyen uses several acquirers
and they do not all use the same set of refusal messages so an accurate table
cannot be provided. Generally a 000 response should be treated as an approval
and any other value as a decline.
Error and Exception transactions will indicate the error code in the table below
and fault in the text of the response and MeS will return a 351 Payment Gateway
error code.

The response control interface allows users to request specific fields to be returned in
certain API responses. Response control request parameters all begin with the prefix
rctl_. The response field will be the request field name with the rctl_ prefix removed.
Example: If the rctl_product_level parameter is set in the request then the product_level
parameter will be returned in the response.
The response parameter will only be returned if the corresponding request parameter has
one of the following values: yes, y, true. The value of the request parameter is not case
sensitive.

Merchant configures the MeS FraudDeflector via the Payment Gateway.
Merchant processes transactions routed to the Payment Gateway.
Based on MeS FraudDeflector settings, the Payment Gateway routes for both

12.4 Fingerprint Integration
The MeS Fraud Deflector can be enhanced by additionally providing a digital fingerprint of the cardholder. The
fingerprint contains many additional key data points for fraud evaluation, allowing Fraud Deflector to make a
more accurate recommendation.
In order to obtain the fingerprint, several elements need to be added to a merchant-hosted checkout page.
1.
The following JavaScript should be added in the HTML head area:
<script type="text/javascript"
src="https://ds.bluecava.com/V50/LD/BCLD5.js"></script>
<script type="text/javascript">
BCLD.getSnapshot(successFunc, errorFunc);
function successFunc(fp, warningMessage) {
var fingerprintData = document.getElementById('bcfp');
fingerprintData.value = fp;
}
function errorFunc(errorMessage) {
// Add debugging here if needed
}
</script>
2.
Next, the following DIVs need to be embedded anywhere in the HTML body:
<div id="BCLDGuidDiv" style="border: 0px; width: 0px; height: 0px;"></div>
<div id="BCLDflashplayer" style="border: 0px; width: 0px; height: 0px;"></div>

3.
The Digital Fingerprint, will need to be sent to the merchant’s web host where it will then be forwarded
to the MeS Payment Gateway. This is typically accomplished by embedding a hidden input element
into the checkout form itself.
The following is an input element that should be embedded into a FORM element:
<input type="hidden" id="bcfp" name="bcfp"/>
4.
Lastly, in order for the process to function properly, a page named BCLD.html must be hosted by the
merchant in the same location as the checkout page. This page may be empty.

ACCEPT: transaction will process as requested. Sale transactions will be
captured and settled in the next batch close cycle. Pre-Authorization transactions
may be captured by the merchant for processing.
MANUAL_REVIEW: Sale requests are initially treated as a Pre-Authorization, if
accepted it will convert to a sale and settle in the next batch close cycle. If
denied, the Payment Gateway will issue and authorization reversal request.
DENY: transaction was not authorized, if an override is initiated the transaction
will go out for an authorization and if approved (and a sale request) will capture
the transaction. If the request was a Pre-Authorization, approved transactions
may be captured by the merchant for processing.

Chapter 13 – Batch Processing
Another processing option using the Payment Gateway interface, allows clients to submit
a batch of transactions for processing. A file is delivered using the gateway name/pair
values. MeS will email confirmation that the file was received and a follow up email once
the batch has been processed.
Batches may be submitted and response files retrieved via the MeS web portal or via an
API call. Processing time will vary depending on the transaction type and overall size of
the batch, however all batches will be processed within 24 hours of submission.
The batch processing option may be used for large recurring files that require both
authorization and capture (sale transaction), or in conjunction with the Payment Gateway
(ex: captures at the end of day for all online authorizations).
There are some functions in the Payment Gateway that may not be ideal when submitting
transactions in a batch mode. Because some transactions rely on access to the database
to reference a prior transaction, care should be taken to refrain from submission of
transactions that require this access. While not typical, sending multiple settlements for a
single authorization concurrently is not recommended within the same batch. In addition,
transactions such as a settlement followed immediately by a void, etc. should also be
avoided.
13.1 Submitting a Request File
13.1.1 Upload via MeS Web Portal
