»Validate Login MFA Request

This endpoint validates a login request which is subject to MFA validation.

»Parameters

• mfa_request_id (string: <required>) – A unique identification of an MFA restricted login request. This can be found in the MFA requirement included in the auth response of the login request.

• mfa_payload (map<string|[]string>: <required>) - A map of login MFA methodIDs to passcode credentials. MFA methodIDs are UUID strings which are used as keys of the map. The values of the map are string slices. In cases where an MFA method is configured not to use passcodes, the passcode remains an empty string.
