Omit `paymentDetailId` to use the recipient’s default. Like every destination, the result expires after 24 hours and can be spent once. This is the short path for a recipient you have already saved: no routing fields, no re-verification of what you sent last time. A recipient with no payment details at all cannot produce a destination — `409 recipient_payment_detail_required`. Add a detail first. ## Legacy details A payment detail whose routing values live at the provider rather than with Sakawave is marked `providerLocked`. Sakawave will try to resolve it; when it cannot, you get `409 payment_detail_provider_locked` and the fix is to delete that detail and add it again with its routing fields. ## Error codes | Status | `code` | Cause | | - | - | - | | `400` | `validation_failed` | An identifier is not a ULID. | | `404` | `payment_detail_not_found` | The named detail does not belong to this recipient. | | `409` | `recipient_payment_detail_required` | The recipient has no payment detail to use. | | `409` | `payment_detail_provider_locked` | A legacy detail that must be re-entered before it can be used. | | `409` | `payment_detail_incomplete` | The stored detail is missing routing data the route needs. | | `409` | `currency_capability_unavailable` | The destination currency is closed for external transfers. | | `409` | `transfer_provider_unavailable` | No provider is currently bound to the route. | | `422` | `recipient_profile_incomplete` | The saved recipient is missing `relationship`, `email`, `address.line1`, `address.city`, or `address.country`. Every missing field is listed in `errors`. | | `503` | `provider_unavailable` | The provider could not be reached. Retry shortly. | | `401` | `INVALID_API_KEY` | The key is missing, invalid, inactive, expired, from the other environment, or blocked by its IP allowlist. | | `404` | `recipient_not_found` | No such recipient for this business, or it has been deleted. | | `429` | `api_key_rate_limit_exceeded` | The per-minute limit for this key was exceeded. All of these operations share a 120-per-minute allowance. | ## OpenAPI ````yaml /openapi.json post /v1/transfer-destinations/recipients/{recipientId} openapi: 3.1.0 info: title: Sakawave Business API version: 1.0.0-draft summary: >- Accounts, transfers, FX quotes, and transaction reconciliation for Sakawave businesses. description: >- Generated from the public NestJS controllers and their Zod request schemas.
