The destination, asset/network, limits, screening, and available balance must all be eligible. ## Money and balance effect On acceptance, the source debit is reserved. It is captured after confirmed execution or released only when non-execution is proven. ## States and completion `accepted` means funds are reserved, not sent. Follow submission, blockchain confirmations, finality, failure, hold, and reconciliation state. ## Safe retries Send a unique `Idempotency-Key` for the logical action. If the response is lost, retry the same payload with the same key; never create a new key merely because the first response timed out. Read [Conversions and withdrawals](/treasury/conversions-and-withdrawals) for the complete workflow. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/treasury/withdrawals openapi: 3.0.0 info: title: Wayex API description: >- Wayex APIs for direct customer payment routes and isolated, prefunded Treasury accounts.
