So, you could add additional data to the automatically generated schema.

For example, you could decide to read and validate the request with your own code, without using the automatic features of FastAPI with Pydantic, but you could still want to define the request in the OpenAPI schema.

You could do that with `openapi_extra`:

import java.util.Map;

import jcifs.CIFSException;
import jcifs.util.Hexdump;

/**
 * There are hundreds of error codes that may be returned by a CIFS
 * server. Rather than represent each with it's own <code>Exception</code>
 * class, this class represents all of them. For many of the popular
 * error codes, constants and text messages like "The device is not ready"
 * are provided.
 * <p>

      return true
    }
  }

            assertEquals(100, response1.getCount());

            assertEquals(200, response2.getCount());
            assertEquals(100, response2.getRemaining());

## Documenting the callback { #documenting-the-callback }

The actual callback code will depend heavily on your own API app.

And it will probably vary a lot from one app to the next.

It could be just one or two lines of code, like:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
