A Trace ID is an identifier used by issuers and schemes to reference the original transaction that set up a subscription or recurring payment series. This can help them to:
- Identify the original transaction from the cardholder.
- Confirm that the cardholder authenticated the transaction in regions where Strong Customer Authentication (SCA) is required.
You can provide the Trace ID in the previous_payment_id field when you make a call to the Payments endpoint.
In some regions, providing a Trace ID is mandatory. Visa and Mastercard may issue fines for subsequent recurring and subscription payments that do not include the Trace ID.
For more information, see our Recurring payments with stored card details documentation.
