Retries and asynchronous work

This operation reads or validates without applying a resource mutation. Respect rate limits and credential lifetime.

HTTP 202 means the background job was accepted. Use the returned job ID to check its status. Download results when the job is complete, or inspect its error or cancellation status.

Request examples

Replace demo IDs, timestamps and placeholders with your own values. For a retry, keep the same IDs, time and content. These examples do not run requests on this page.

Keep login links, codes, cookies and keys private. Do not print them in logs or share them in support requests.
