You could create an API with a *path operation* that could trigger a request to an *external API* created by someone else (probably the same developer that would be *using* your API).

The process that happens when your API app calls the *external API* is named a "callback". Because the software that the external developer wrote sends a request to your API and then your API *calls back*, sending a request to an *external API* (that was probably created by the same developer).

That command created a file `docs/ht/mkdocs.yml` with a simple config that inherits everything from the `en` version:

```yaml
INHERIT: ../en/mkdocs.yml
```

!!! tip
    You could also simply create that file with those contents manually.

That command also created a dummy file `docs/ht/index.md` for the main page, you can start by translating that one.

That extra info will be added as-is to the output **JSON Schema** for that model, and it will be used in the API docs.

Routes are declared in a single place, using functions declared in other places (instead of using decorators that can be placed right on top of the function that handles the endpoint). This is closer to how Django does it than to how Flask (and Starlette) does it. It separates in the code things that are relatively tightly coupled.
