With **FastAPI**, using OpenAPI, you can define the names of these webhooks, the types of HTTP operations that your app can send (e.g. `POST`, `PUT`, etc.) and the request **bodies** that your app would send.

This can make it a lot easier for your users to **implement their APIs** to receive your **webhook** requests, they might even be able to autogenerate some of their own API code.

	Progress rebalPoolProgress `json:"progress"` // is empty when rebalance is not running
}

// rebalanceAdminStatus holds rebalance status related information exported to mc, console, etc.
type rebalanceAdminStatus struct {
	ID        string                // identifies the ongoing rebalance operation by a uuid
	Pools     []rebalancePoolStatus `json:"pools"` // contains all pools, including inactive

Using it in your editor is what really shows you the benefits of FastAPI, seeing how little code you have to write, all the type checks, autocompletion, etc.

## Install FastAPI { #install-fastapi }

The first step is to install FastAPI.

Si vous avez besoin de réaliser des traitements lourds en tâche d'arrière-plan et que vous n'avez pas besoin que ces traitements aient lieu dans le même process (par exemple, pas besoin de partager la mémoire, les variables, etc.), il peut s'avérer profitable d'utiliser des outils plus importants tels que <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>.

Ici, `item_id` est déclaré comme `int`.

/// check | vérifier

Ceci vous permettra d'obtenir des fonctionnalités de l'éditeur dans votre fonction, telles
que des vérifications d'erreur, de l'auto-complétion, etc.

These users have [created the most Pull Requests](help-fastapi.md#create-a-pull-request){.internal-link target=_blank} that have been *merged*.

They have contributed source code, documentation, etc. 📦

<div class="user-list user-list-center">

{% for user in (contributors.values() | list)[:50] %}

{% if user.login not in skip_users %}

It's relatively tightly coupled with relational databases (like MySQL or PostgreSQL), so, having a NoSQL database (like Couchbase, MongoDB, Cassandra, etc) as the main store engine is not very easy.

## Contents properties

All properties except the file size are tied to the zip file. This means that modification date, headers, tags, etc. can only be set for the zip file as a whole. In similar fashion, replication will replicate the zip file as a whole and not individual files.

## Code Examples

/// note | Nota

Solo puedes usar `await` dentro de funciones creadas con `async def`.

Si estás usando un paquete de terceros que se comunica con algo (una base de datos, una API, el sistema de archivos, etc.) y no tiene soporte para usar `await` (este es actualmente el caso para la mayoría de los paquetes de base de datos), entonces declara tus *path operation functions* como normalmente, usando simplemente `def`, así:

```Python hl_lines="2"

```

Puedes pensar en `APIRouter` como una clase "mini `FastAPI`".

Se soportan todas las mismas opciones.

Todos los mismos `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip | Consejo

En este ejemplo, la variable se llama `router`, pero puedes nombrarla como quieras.
