Bing Speech API using REST

Hey guys,
I want to use the Bing Speech API in my Project, but I don’t know how to implement it.
The examples they are showing are in C#, curl or Powershell. I don’ know anything about HTTP requests and how to send
the Authentification token and the audio file.
Here are the examples they are showing: Migrieren von der Bing-Spracheingabe zum Speech-Dienst - Azure Cognitive Services | Microsoft Docs

Can you guys help me? I searched for days and can’t seem to get it…
