Retries and asynchronous work
This change does not have a general retry guarantee. If the response is unclear, read the affected resource before trying again. Follow Retry-After waiting times and request new sign-in or action codes when they expire.
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.
