# Answer MFA Questions

`PATCH /v3/{customerId}/BankingServices/AnswerMFAQuestions`

The `AnswerMFAQuestions` endpoint allows you to submit responses to multi-factor authentication questions in order to complete the authentication process and refresh the associated financial card.

**Availability:**
This endpoint is supported only in Canada and only for institutions using simple security questions as their MFA method.

**Note:** This endpoint is specific to the Enhanced MFA flow, which preemptively collects simple security question answers to improve Nightly Refresh success. It does not handle advanced MFA types such as two-step verification, push notifications, or other specialized authentication mechanisms. Those are fully supported through Flinks' standard authentication flow via the [/Authorize](/api/authorize/endpoints/authorize) endpoint and Flinks Connect.
