Does there exist any specifications for HTTP 202 status monitors? : <p>The <a href="https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.2.3" rel="nofollow noreferrer">HTTP 202 Accepted</a> response is used to accept a task for background processing, and optionally providing a separate URL for monitoring the progress of the task. All <a href="https://stackoverflow.com/questions/14832983/http-status-202-how-to-provide-information-about-async-request-completion">answers</a> and <a href="https://restfulapi.net/http-status-202-accepted/" rel="nofollow noreferrer">posts</a> I've read about it basically suggest everyone to invent their own response types for the submission and monitoring endpoints.</p>

<p>Does there exist any specifications / proposals / conventions (followed by multiple companies) as to how the monitoring URL is returned (an HTTP header or response payload) or what the structure of the monitoring API response is?</p>

<p>Failing that, does any big names (Google, Twitter, etc) implement this pattern in their public APIs, from which to gain insight?</p>
