title: Can't register callback url - Watson Speech to text API
body: <p>I have been working with the Watson speech to text API without an issue for 2 months, but today a problem came while trying to register a callback url, the curl request is as follows:</p>
  
  <p>curl -X POST -u "{my-usernanem}":"{my-password}" "<a href="https://stream.watsonplatform.net/speech-to-text/api/v1/register_callback?callback_url=https://www.google.com" rel="nofollow noreferrer">https://stream.watsonplatform.net/speech-to-text/api/v1/register_callback?callback_url=https://www.google.com</a>"</p>
  
  <p>and the traceback:</p>
  
  <p>{"code":400,"code_description":"Bad Request","error":"unable to register callback url '<a href="https://www.google.com" rel="nofollow noreferrer">https://www.google.com</a>', callback server responded with status code 400"}</p>
  
  <p>I am using google.com to ilustrate that it isn't making the get request, in my app I use another URL and when I check the logs there isn't a request to the specified URL, i.e. it is not trying to whitelist it.</p>
  
  <p>Can anyone help me?</p>
