## Documentation Tags - OpenAPI { #documentation-tags-openapi }

To add tags to your *path operations*, and group them in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Tags](../tutorial/path-operation-configuration.md#tags).

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

///

## Write the callback documentation code { #write-the-callback-documentation-code }

This code won't be executed in your app, we only need it to *document* how that *external API* should look like.

But, you already know how to easily create automatic documentation for an API with **FastAPI**.

## Мітки документації - OpenAPI { #documentation-tags-openapi }

Щоб додати мітки до ваших *операцій шляху* та згрупувати їх в інтерфейсі документації, прочитайте документацію [Навчальний посібник - Налаштування операції шляху - Мітки](../tutorial/path-operation-configuration.md#tags).

## Resumo e Descrição da documentação - OpenAPI { #documentation-summary-and-description-openapi }

Et bien sûr, cela prend en charge la même chose :

* validation des données
* sérialisation des données
* documentation des données, etc.

Cela fonctionne de la même manière qu'avec les modèles Pydantic. Et, en réalité, c'est mis en œuvre de la même façon en interne, en utilisant Pydantic.

Ensuite, ouvrez la documentation de la sous‑application à [http://127.0.0.1:8000/subapi/docs](http://127.0.0.1:8000/subapi/docs).
