May 2024

16 days ago by Christina Sherby

In May 2024, we added the ability to send payment remittance details, added for Mastercard’s merchant advice codes, clarified URI format and dispute IDs, added ICC data fields, moved some endpoints to a new location and added information about user-defined account fields. Click May 2024 to see the details.

Payment remittance information

We have added the ability to send payment remittance information for ACH debit or credit payments.

Merchant advice codes

We have added support for Mastercard’s merchant advice codes (MAC) 03, 40, and 41 to help reduce the number of declined recurring transactions for you or your issuer. Contact Galileo if you are interested in receiving MAC decisioning and overrides via the Auth API.

URI format

We have added an alert to the Authentication reference page to emphasize the standard URI format for endpoint calls.

New ICC data fields

There are new ICC data fields available for advanced_auth_api_fields in the Auth API:

  • DE048 SE33 — PAN Mapping File Information
  • Tag 9F10 — Issuer Application Data (IAD)
  • Tag 9F34 — Cardholder Verification Method (CVM) results

Dispute tracking

We added a Tracking disputes section to Disputes at Galileo to show how to correlate the identifiers in the dispute-related event messages with the RDFs.

Transaction Simulation endpoint relocation

We moved incoming ACH and card transaction simulation endpoints to a new location in the Reference section.

User-defined account field details

To the About Accounts guide we added the User-defined account fields section to explain how to use these fields to append custom information to your accounts.
