Der Benutzer Ihrer API (ein externer Entwickler) erstellt mit einem POST-Request eine Rechnung in Ihrer API.

Dann wird Ihre API (beispielsweise):

* die Rechnung an einen Kunden des externen Entwicklers senden.
* das Geld einsammeln.
* eine Benachrichtigung an den API-Benutzer (den externen Entwickler) zurücksenden.

**FastAPI**를 사용하여 OpenAPI와 함께 웹훅의 이름, 앱이 보낼 수 있는 HTTP 작업 유형(예: `POST`, `PUT` 등), 그리고 보낼 요청의 **바디**를 정의할 수 있습니다.

이를 통해 사용자가 **웹훅** 요청을 수신할 **API 구현**을 훨씬 쉽게 할 수 있으며, 경우에 따라 사용자 API 코드의 일부를 자동 생성할 수도 있습니다.

/// info

웹훅은 OpenAPI 3.1.0 이상에서 지원되며, FastAPI `0.99.0` 이상 버전에서 사용할 수 있습니다.

## 웹훅이 포함된 앱 만들기

**FastAPI** 애플리케이션을 만들 때, `webhooks` 속성을 사용하여 *웹훅*을 정의할 수 있습니다. 이는 `@app.webhooks.post()`와 같은 방식으로 *경로(path) 작업*을 정의하는 것과 비슷합니다.

    DnsOverHttps
      .Builder()
      .client(bootstrapClient)
      .url("https://dns.google/dns-query".toHttpUrl())
      .bootstrapDnsHosts(getByIp("8.8.4.4"), getByIp("8.8.8.8"))
      .post(true)
      .build()

  private fun buildCloudflareIp(bootstrapClient: OkHttpClient): DnsOverHttps =
    DnsOverHttps
      .Builder()
      .client(bootstrapClient)
      .url("https://1.1.1.1/dns-query".toHttpUrl())

   prevent flakiness from multiple threads concurrently accessing a stream.

## Version 1.5.3

_2014-03-29_

 * Fix bug where the Content-Length header was not always dropped when
   following a redirect from a POST to a GET.
 * Implement basic support for `Thread.interrupt()`. OkHttp now checks
   for an interruption before doing a blocking call. If it is interrupted,
   it throws an `InterruptedIOException`.

## Version 1.5.2

## Webhooks mit **FastAPI** und OpenAPI dokumentieren

Mit **FastAPI** können Sie mithilfe von OpenAPI die Namen dieser Webhooks, die Arten von HTTP-Operationen, die Ihre Anwendung senden kann (z. B. `POST`, `PUT`, usw.) und die Request**bodys** definieren, die Ihre Anwendung senden würde.

        // Parse each extension.
        var pos = 0
        while (pos < header.length) {
          val extensionEnd = header.delimiterOffset(',', pos)
          val extensionTokenEnd = header.delimiterOffset(';', pos, extensionEnd)
          val extensionToken = header.trimSubstring(pos, extensionTokenEnd)
          pos = extensionTokenEnd + 1
