# invalid_target

> OAuth (Sign in with Tickwire): the resource parameter is not the Tickwire MCP server.

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

HTTP 400.

**Likely causes:**

- resource names another server, or several resources were requested.
- At the token endpoint, resource differs from the one the grant was issued for.

**What to do:** Send resource set to the Tickwire MCP server URL: the same address you gave the app, shown on the AI agents page.

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