Customers

Send a unique key, 1 to 255 characters, on every POST. A retry with the same key and the same body returns the first answer instead of acting twice (with Idempotent-Replayed: true); the same key with another body is refused. Keys are kept 7 days, except on POST /v1/checkout/sessions, POST /v1/checkout/sessions/{session} and POST /v1/webhook_endpoints, where a key holds 24 hours; webhook endpoint keys are also capped at the newest 32 per store and mode. Do not rely on a replay after that window. GET and DELETE ignore it.

Optional. The only version Fluveo serves is 2026-05-27.dahlia; any other value is refused with a 400. Every answer names that version in its own Fluveo-Version header, except the refusals Fluveo gives before it reads the request (no key, an unknown key, an unknown URL, a body that is not a form) and a file's bytes, which name no version and no Request-Id.
