PUT Commit a Transaction

PUT /transfer/v1/transactions/{transactionId}/commit

Development Guide

The 'Commit a Transaction' endpoint executes the transactionId and completes the transfer of funds.



1. Prepare headers & authentication:

The application must call the 'Commit a Transaction' endpoint with a PUT HTTP method, providing the OAuth access_token and all other required header values.


Note: MoneyGram uses the OAuth 2.0 framework. The application must use their OAuth client credentials to generate an access_token by calling the Get access token endpoint. The token is valid for 1 hour and must be passed as a header value in all subsequent API HTTP calls. Learn More

2. Provide the transactionId resource as a path parameter and the prepare the request body

The application must persist the transactionId from the Update or Create a transaction endpoint and apply it as a path parameter to the Commit a transaction endpoint.

3. Display Fraud Warnings & Pre-disclosure in application UI:

It is a regulatory requirement to display Fraud Warnings (US Only, Global) and a Pre-Payment Disclosure to the consumer before the transfer of funds is executed. Both the Fraud Warnings and Pre-payment Disclosure must be displayed for all transactions (i.e. in all send countries, for all amounts, for all service options).




4. Make a request and handle the response:

The application must call the 'Commit a transaction' endpoint with a PUT HTTP method. The application must build to handle the following response scenarios:


  • Success | Parse the Response | | 200 OK HTTP Status
    When the 'Commit a transaction' endpoint responds with a 200 HTTP Status the application has finalized and executed the transfer. The response payload, will return the following fields referenceNumber, and expectedPayoutDate. The funds are marked for "settlement" on the MoneyGram ledger.

  • Failed | Handle the Error | 400 Bad Request HTTP Status
    When the 'Commit a transaction' endpoint responds with 400 Bad Request HTTP Status a specific error message/s will be returned. The application will need to resolve these errors and resubmit the transaction for commit.

5. You're Done! Communicate the reference number to consumer:

It is recommended to prominently display the referenceNumber on the application UI and send a notification to the consumer.




Business Rules to Code


🔍

  1. Idempotent: If the application does not receive a response from the Commit a Transaction API within 10-40 seconds, the application must send the request again. This must be retried up to 3 times. If the retry attempt fails, check the transactionStatus using the Status API to confirm if transaction was successful.

  2. Error Code 935: If error code 935 internal system error is returned on commit, it must be handled the same way as if the commit response is not received (see item 2).

  3. Handling Errors: Other errors can be returned on commit a transaction stopping the transaction. The application must handle scenarios where the transaction fails (an error code is returned) on commit. Learn More

  4. Receipts: Refer to Receipts module for detailed information and requirements for receipts.

  5. Start online, fund in store: If a digital application wants to fund the transactions in store they should have market the "fundInStore": true on the Update API, the Commit API is not needed.

  6. Reference Number Recycling policy: MoneyGram will recycle the reference numbers after the transactions have been closed/received for 4 to 6 months. If you are storing reference numbers in your database, you should also store the transaction date. The combination of the reference number and transaction date will be the unique key for a transaction.
