POST/digitalwallets/postTokenizationAuthenticationDecision

Use this endpoint to submit a post-tokenization authentication decision from the customer to Marqeta in a secure card on file scenario. Marqeta validates the request, stores it, and forwards the authentication decision to Mastercard Digital Enablement Service (MDES) in real time. Marqeta then returns the MDES response back to the customer synchronously. This enables issuers to notify MDES of the cardholder's authentication outcome following tokenization, ensuring that the token requestor receives timely and accurate decisioning.
