  2. Ensure the redirect URI does not have query parameters or fragments unless explicitly allowed.

Dead Ends

Common approaches that don't work:

  1. 50% fail

    The mismatch is often a missing trailing slash or different casing; adding one may not fix if the registered URI lacks it.

  2. 90% fail

    Most OAuth providers do not allow wildcards for security reasons.

  3. 100% fail

    The error is deterministic; retrying without fixing the URI pattern will always fail.
