FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

# Exceptions - `HTTPException` and `WebSocketException`

These are the exceptions that you can raise to show errors to the client.

When you raise an exception, as would happen with normal Python, the rest of the execution is aborted. This way you can raise these exceptions from anywhere in the code to abort a request and show the error to the client.

You can use:

* `HTTPException`
* `WebSocketException`

## Documentation Summary and Description - OpenAPI { #documentation-summary-and-description-openapi }

To add a summary and description to your *path operations*, and show them in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Summary and Description](../tutorial/path-operation-configuration.md#summary-and-description){.internal-link target=_blank}.
