Read the provider's sign-in in flight
The state of the sign-in startProviderAuth last began for this provider: still pending with the URL to open, complete, or failed with the reason. This is how a client learns the outcome of a browser or device-code flow the host is driving on its behalf — the provider’s own authState says whether a credential exists, this says what happened to the last attempt to get one. 404 when this host has no attempt on record for the provider.

128^[a-z0-9][a-z0-9-]*$Response
The last sign-in attempt for this provider.
A sign-in flow, in flight or finished. When browserUrl is present the client opens it; completion is reflected in the provider's authState.
pending means the host is still driving the flow — poll getProviderAuth. complete means a credential was probed and stored. failed means this attempt is over and message says why; nothing was stored.
pending, complete, failed URL the user opens to complete a browser-based flow.
Human-readable instruction, for example a device code to enter — and, on a failed status, why the sign-in failed. It never carries the key or token itself.
1024When the pending flow expires.
