## REST API call to plugin

To verify the custom token presented in the `AssumeRoleWithCustomToken` API, MinIO makes a POST request to the configured identity management plugin endpoint and expects a response with some details as shown below:

### Request `POST` to plugin endpoint

/// warning

You can declare multiple `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `application/x-www-form-urlencoded` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.
