Retries

Idempotency key required, with expectedRevision

MCP

Not offered over MCP: Choosing and sharing a personal subscription is the signed-in person's explicit choice in Settings or the CLI, never an agent's delegation.

Fields

choiceobjectRequired
expectedRevisionintegerRequired
The record's current revision, from the last time you read it. If someone changed the record since, the request is refused with a conflict so you can reload and check before trying again.
0 to 9007199254740991
idempotencyKeystringRequired
Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match.
