Parameters and headers
| Field | Location | Type and limits | Required | Meaning |
|---|---|---|---|---|
| Origin | Header | string; {"format":"uri"} | Yes | The same HTTPS origin as the public browser site. Required for browser login and provider-start requests. |
Request body
| Field | Type and limits | Required | Meaning |
|---|---|---|---|
| $ | object; {"additionalProperties":false} | Yes | — |
| $.token | string | Yes | One-time token or access token for the purpose documented by the operation. Treat it as a secret. |
Responses
| Header | Type and limits | Meaning |
|---|---|---|
| Cache-Control | string; {"pattern":"(?:^|,\\s*)no-store(?:,|$)"} | Private API responses prohibit storage. Public OAuth metadata is cached for 300 seconds; live streams additionally prohibit transformation. |
| Content-Language | string; {"enum":["en","de"]} | Language of human-readable response text, resolved from Accept-Language or the documented browser preference. Technical codes and identifiers remain stable. |
| Referrer-Policy | JSON; {"enum":["strict-origin-when-cross-origin","no-referrer"]} | The default referrer policy is strict-origin-when-cross-origin. Provider-login responses use no-referrer to protect login parameters. |
| Vary | string | Responses vary by Accept-Language; browser-rendered responses can also vary by the preference cookie. |
| X-Content-Type-Options | JSON; {"const":"nosniff"} | The browser must use the declared content type. |
| X-Frame-Options | JSON; {"const":"DENY"} | The response must not be embedded in a frame. |
| X-Request-ID | string | Server-generated request identifier. Include this when reporting an error; inbound values are not trusted. |

}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.

- POST Request a code for one sensitive action
Request a six-digit confirmation code for a sensitive account or workspace change. It lasts five minutes and allows five incorrect attempts. Use the same signed-in browser, action, target and parameters when confirming. A replacement requested after 60 seconds invalidates the previous code for that action. For your own account use link_identity, unlink_identity, add_passkey, remove_passkey or delete_self; workspace membership actions require owner permission. Do not use sign-in codes to confirm changes.
- DELETE Cancel your pending action confirmation
Only an outstanding confirmation belonging to the current account and session can be cancelled.
- DELETE Cancel the browser entry flow
Cancels outstanding email challenges and the browser-bound entry flow, then clears its pre-authentication cookie. It does not revoke an existing application session. Requires the allowed browser origin.
