title: Making calls to Azure Devops API endpoints from a 3rd party server
body: <p>I have a project where:</p>
  
  <ol>
  <li>I create/add a label on an issue at a Github Repo.</li>
  <li>Github initiates a call to my server via webhooks.</li>
  <li>I do some stuff backend, and if ok decide to make a call to Azure Devops to open a card.</li>
  </ol>
  
  <p>My question is the 3rd step. I looked through the <a href="https://docs.microsoft.com/en-us/rest/api/azure/devops/?view=azure-devops-rest-5.1&amp;viewFallbackFrom=azure-devops" rel="nofollow noreferrer">REST API documentation</a> / <a href="https://docs.microsoft.com/en-us/azure/devops/integrate/get-started/authentication/authentication-guidance?view=azure-devops" rel="nofollow noreferrer">authorization</a>, but I cannot find anything related to authenticating from a 3rd party server.</p>
  
  <p>Any idea/documentation or even using a third party app solution to bypass (Github -> My server -> Some other 3rd party app -> Azure) is appreciated.</p>
