Idempotency

initiate

Idempotent by reference scoped to your API key. Replaying the same body returns the existing escrow / checkout when a funding account is already provisioned.

deliver / release

Both endpoints are safe to retry. Deliver returns already_delivered; release returns already_released when the work is done.

Idempotency-Key header

A general-purpose Idempotency-Key store exists in the platform for selected routes. For merchant escrow create, prefer a stable reference as your business idempotency key — it is already enforced.
