Retries and asynchronous work

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

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.

  • HTTP API, OAuth and MCP

    Find the user API endpoints, their permissions, fields, examples and response formats.

  • POST Complete passkey sign-in

    Checks the signature, user verification, origin, account status and browser-bound single-use challenge before creating a normal session. Errors do not reveal account existence. Limit: forty attempts per network address in fifteen minutes.

  • POST Start passkey sign-in

    Creates a discoverable challenge without an email address or account lookup. Requires the configured Origin and a browser-bound cookie. Limit: twenty starts per network address in fifteen minutes.

  • POST Complete passkey enrollment

    Complete passkey registration using the device's WebAuthn response in the same signed-in browser. Each account can store up to ten passkeys.
