Edit on Github Send Feedback develop

FIDO2 REST API enables integration of WebAuthN standard into PowerAuth for FIDO2 authenticators. Registration and authentication ceremonies are supported by this REST API.

Possible Error Codes

The API may return one of the following error codes:

HTTP Error Code Description
400 ERROR_FIDO2_AUTH Error related failed FIDO2 assertions.
400 ERROR_FIDO2_REQUEST Error related failed FIDO2 request processing.
400 ERROR_HTTP_REQUEST Request did not pass validation (mandatory property missing, null/invalid value).
401 ERROR_UNAUTHORIZED Returned in the case authentication fails (invalid application credentials).
404 ERROR_NOT_FOUND Returned in the case URL is not present (calling wrong API).
