Adding an OAuth Provider:

Once the above steps have been completed, Jack Henry must be added as an OAuth Provider within the project. 

Navigate to Manage > Integrations > OAuth > Providers. Click Add OAuth Provider. 

Provide a name for the OAuth Provider. In this example, "JHenryAuth," is used. Set the OAuth Version to OAuth2. Fill in the URL and Key fields with appropriate URLs and keys, respectively.

Toggle the Use Proof Key for Code Exchange (PKCE) setting to True.

Once Jack Henry has been successfully added as an OAuth Provider, a Jack Henry OAuth Token must be created.

Adding an OAuth Token:

Navigate to Manage > Integrations > OAuth > Tokens. Click Create Token. Provide a name for the Token, select JHenryAuth as the Provider, and fill out the rest of the fields with unique identifiers associated with a Jack Henry developer account.

Use Case: Retrieving the Last Transaction of an Account

Navigate to Integration > Internal Services > Call Internal Decisions Service, and drag the step into the Flow. Select OAuthTokenService as the Service, and select RefreshAccessToken as the Method. Enter the Token ID from the previously created Token.

Add the Get All Transactions step to the end of the RefreshAccessToken step. 

The configuration below will retrieve a maximum of 20 transactions that occurred between 07/01/2026 and 07/06/2026 for the specified Account ID at the designated financial institution.

Lastly, add the Get Transaction step to the Get All Transactions step. Set Flow Data as the input type for Transaction ID. In the Pick Data For transactionId window, select GetAllTransactions1_Output > From Transactions > From All Ids > Last. This will retrieve the last Transaction ID from the output list.

Connect the Get Transaction output to the End step. Save the Flow and run the Debugger to ensure it is working properly.
