public GetAssertionCallbacks(Action<string, object> qrcodeCallback, Action<PubkeyCredAssertion, WauthnError, object> responseCallback, Action<HybridLinkedData, WauthnError, object> linkedDataCallback, object userData)
Parameters
Type Name Description
System.Action<T1, T2><string, object> qrcodeCallback

Callback function for displaying QR code. The qr_contents are encoded as you can see in the encodeQRContents() function of the FIDO specification: https://fidoalliance.org/specs/fido-v2.2-rd-20230321/fido-client-to-authenticator-protocol-v2.2-rd-20230321.html#hybrid-qr-initiated. The qr_contents is encoded like "FIDO:/0254318383..........7406596245". The image to be displayed shall be created from qr_contents with media vision API (). If the request does not need to display a QR code then this callback function won't be invoked.
System.Action<T1, T2, T3><PubkeyCredAssertion, WauthnError, object> responseCallback

Callback function for getting the final response. Invoked when the response for the GetAssertion request need to be returned. The result of the GetAssertion request may be one of the following:

  • None if the request is completed well,
  • Canceled if the request is cancelled by a Cancel() request.
  • InvalidState if the server entered invalid state. Known causes:
  • proxy issues,
  • reached the limit of credentials stored by the authenticator.
  • TimedOut if the request times out. Known causes:
  • authenticator does not respond during state assisted transactions due to lack of push notifications support (e.g. missing Google Account).
System.Action<T1, T2, T3><HybridLinkedData, WauthnError, object> linkedDataCallback
