An example of an "application/json" formatted body would appear as follows: Now that you have the service's request URI and have created the related request message header and body, you are ready to send the request to the REST service endpoint. In short, this involves. I have created a generic service connection in DevOps without username/password, and assigned that to the Invoke REST API task. Platform- and language-neutral OAuth2 service endpoints, which we use in this article. This functionality is useful, for example, if you wish to let users know the check is waiting on an external action, such as someone needs to approve a ServiceNow ticket. Next, your client needs to redeem the authorization code for an access token. When you call Azure DevOps Services APIs for that user, use that user's access token. You see this property when the results are too large to return in one response. The URI contains the following query-string parameters, which are specific to your client application: client_id: A GUID that was assigned to your client application during registration, also known as an application ID.
