# invalid_redirect_uri

> OAuth (Sign in with Tickwire): a registered redirect URI is not allowed.

Source: https://tickwire.io/docs/errors/invalid_redirect_uri/

HTTP 400.

**Likely causes:**

- Not https, not loopback http, and not a reverse-domain app scheme.
- It has a fragment, user info, backslashes or spaces, or is longer than 2000 characters.
- More than 10 redirect URIs.

**What to do:** Use exact https redirect URIs (or http on 127.0.0.1, [::1] or localhost).

**Retry:** No. The same request gets the same answer; change something first.
