Trustly offers a complete solution to handle legacy ACH ABA Routing Number and Account Number data that exists in your database to meet the new NACHA requirements for account tokenization and verification.

Summary

Account tokenization and verification can be done using Trustly’s Tokenize an Account to validate and or tokenize the existing merchant’s database. The primary steps of this tutorial are:

1. Collect the customers Account and Routing Number in your user interface. Pass this information to Trustly's Tokenize API endpoint.
2. Trustly tokenizes the account information. Account Tokens are unique per merchant per account.
3. If you pass the optional verifyAccount flag with a value of true, Trustly will also verify the account using our own database or a third party service provided by TeleCheck.
4. Trustly returns the token and optional verification data to you via API response or batch file.
5. Update your records with the token and continue processing the transaction.

Tokenize API Endpoint

To initiate the request, pass in the following inputs:

• merchantId: A unique Trustly merchant identifier.
• account.accountNumber: This is the account number entered by the sender.
• account.routingNumber: This is the routing number entered by the sender.

You can optionally pass in more information to the request. For a full list of fields, consult the tokenize API reference.

Example Request

In this example, we use an account number of 123456576 and a routing number of 124003116. We are also requesting optional account verification and passing in optional customer information.
