API v1 · OAuth
invalid_redirect_uri
| HTTP | When |
|---|---|
| 400 | The redirect URI is not registered for this client or is malformed. |
Every redirect_uri used at /authorize and /oauth/token must be
byte-identical to one registered via DCR. Registration also refuses a
URI whose scheme is not allowed — see the redirect_uris field notes in
OAuth §2.1.
Re-register with the correct URI list if yours has changed.
