# OpenAPI Webhooks { #openapi-webhooks }

There are cases where you want to tell your API **users** that your app could call *their* app (sending a request) with some data, normally to **notify** of some type of **event**.

This means that instead of the normal process of your users sending requests to your API, it's **your API** (or your app) that could **send requests to their system** (to their API, their app).

This is normally called a **webhook**.

使用 `async` 和 `await` 的風格在語言中相對較新。

但它使處理異步程式碼變得更加容易。

相同的語法（或幾乎相同的語法）最近也被包含在現代 JavaScript（無論是瀏覽器還是 NodeJS）中。

但在此之前，處理異步程式碼要更加複雜和困難。

在較舊的 Python 版本中，你可能會使用多執行緒或 <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>。但這些程式碼要更難以理解、調試和思考。

在較舊的 NodeJS / 瀏覽器 JavaScript 中，你會使用「回呼」，這可能會導致“回呼地獄”。

## 協程

**協程** 只是 `async def` 函式所回傳的非常特殊的事物名稱。Python 知道它是一個類似函式的東西，可以啟動它，並且在某個時刻它會結束，但它也可能在內部暫停 ⏸，只要遇到 `await`。

这种使用 `async` 和 `await` 的风格在语言中相对较新。

但它使处理异步代码变得容易很多。

这种相同的语法（或几乎相同）最近也包含在现代版本的 JavaScript 中（在浏览器和 NodeJS 中）。

但在此之前，处理异步代码非常复杂和困难。

在以前版本的 Python，你可以使用多线程或者 <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>。但代码的理解、调试和思考都要复杂许多。

在以前版本的 NodeJS / 浏览器 JavaScript 中，你会使用"回调"，因此也可能导致“回调地狱”。

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.
