Supply `externalReference` only when your system already has a stable recipient identifier; otherwise Wayex generates one. ## Before you call Use a secret API key with `treasury:write`. Supply the required recipient and destination data. If a fresh end-client Sumsub share token is available or required by policy, send it in the input-only, single-use `sumsub.shareToken` field on this request. ## Money and balance effect This changes a resource or configuration but does not directly reserve, debit, credit, or settle wallet money. ## States and completion Creation does not guarantee a payout will pass current policy. Evidence, screening, limits, and balance are checked when the payout is submitted. ## 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 [Beneficiaries and payouts](/treasury/beneficiaries-and-payouts) for the complete workflow. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/treasury/beneficiaries openapi: 3.0.0 info: title: Wayex API description: >- Wayex APIs for direct customer payment routes and isolated, prefunded Treasury accounts.
