# Create Payout
> Starts a payout order from a valid quotation that has not expired. Check the wallet address and blockchain first: crypto sent to a wrong address cannot be recovered.
Add the Zapyd "Create Payout" call (`POST /pos/api/v1/payout/initiate`) to my backend. Starts a payout order from a valid quotation that has not expired. Check the wallet address and blockchain first: crypto sent to a wrong address cannot be recovered.
* Sandbox: `POST https://sandbox.zapyd.com/pos/api/v1/payout/initiate`
* Production: `POST https://api.zapyd.com/pos/api/v1/payout/initiate`
JSON body:
* `quotation_id` (string, uuid, required): The unique identifier of the quotation.
* `customer_id` (string, uuid, required): The unique identifier of the customer.
* `client_reference_id` (string, optional): Your reference for this payout. Optional, but must be unique if sent. Example: `testUser123`.
* `transaction_hash` (string, required): Hash of your on-chain transfer of sending\_amount to the quotation's wallet\_address. Each hash can fund one payout only. Example: `0x9f2c3b…`.
Success: HTTP 201, `{status: true, message, data}`. `data`: `id`, `quotation_id`, `customer_id`, `bank_id`, `asset`, `network`, `fiat`, `rate`, `sending_amount`, `receiving_amount` (Fiat amount the beneficiary receives), `client_reference_id`, `fees`, `status`, `wallet_address` (Deposit address from the quotation), `transaction_hash`, `created_at`.
Errors (`{status: false, message, err_code, errors}`):
* 400 `Client Reference ID already exists`
* 400 `Quotation is not found`: Quotation does not exist or does not belong to this organization
* 400 `Customer ID does not match with the quotation`: Customer ID mismatch between payin order and quotation
* 400 `Quotation has expired`
* 400 `Quotation is already linked to another payout`
* 400 `Transaction hash already linked to a payout that is either processing or successful`: The hash already funded another payout
* 500 `Internal Server Error`
Every endpoint can also return 401 `AUTH_*` (signature, timestamp or key: fix, don't retry), and 429 or 5xx (retry with backoff).
Rules:
* Call it after your on-chain transfer of the quotation's `sending_amount` to its `wallet_address`. Zapyd verifies the transfer on-chain, then pays out.
* A `transaction_hash` funds one payout only (EVM hashes are compared case-insensitively). Send a unique `client_reference_id` and store the returned `id`.
* The payout starts as `PROCESSING`. Track it with the `PAYOUT` webhook (no webhook for `PROCESSING`): `SUCCESS` with `metadata.utr` (show it as proof of payment), `IN_REVIEW` (send the user to `metadata.rfi_link` when present, otherwise wait), `FAILED` (always the generic `Payout failed`), `REFUNDED`. Every event carries your `client_reference_id`. Most payouts finish in 30 to 60 minutes; bank delays can take up to 24 hours.
* On a timeout or 5xx, look the payout up in `GET /pos/api/v1/payout/history` before retrying. A retry with a hash that already funded a payout is rejected.
* Sandbox: initiate with the Sepolia transaction hash, then set the result with `PATCH /pos/api/v1/payout/mock-payout-status`.
Signing (every request):
* Headers: `X-API-KEY`, `X-TIMESTAMP` (Unix seconds, within 300 s of server time; generate per request) and `X-SIGNATURE`.
* `X-SIGNATURE` = Base64(HMAC-SHA256(key = API secret, message = apiKey + "|" + timestamp + "|" + canonicalBody)). Base64 of the raw digest, not hex.
* canonicalBody: the JSON body with keys sorted at every nesting level, no whitespace (separators `,` and `:`), and every non-ASCII character escaped as lowercase `\uXXXX` (Python `json.dumps(body, sort_keys=True, separators=(",", ":"))`). Requests with no body (GET, DELETE) sign `{}`. Query parameters are not signed.
* Send the exact canonicalBody string you signed as the request body, with `Content-Type: application/json`.
* Test vector: key `3f1b2c4d-5e6f-4a7b-8c9d-0e1f2a3b4c5d`, secret `test-secret-do-not-use`, timestamp `1735689600`. Signing `{}` gives `6sCtVSRQjU9+2/af8gdwUAvY1l6Ii6ENcbRfanPkhY0=`. Body `{"customer_id":"78c99d71-f28f-47a9-8302-93b286efbe0e","amount":100.5,"currency":"INR","meta":{"note":"Café","b":2,"a":1}}` gives `l+DvQrzlKbsOSxSYOdWoWHEehcFRZfDJPKlLDkm2cSI=`.
Deliver:
1. A typed `createPayout` function in this codebase's language and HTTP client. Reuse an existing Zapyd client and signer, or write one small shared client.
2. Config from `ZAPYD_API_KEY`, `ZAPYD_API_SECRET` and `ZAPYD_BASE_URL`. The secret stays on the server, never in a browser or app.
3. Return `data`. When `status` is false, throw an error with the HTTP status, `err_code`, `message` and `errors`. Don't show raw errors to end users.
4. Retry only 429 and 5xx: exponential backoff from 1 s, capped at 30 s, at most 5 attempts.
5. Amounts as strings. Types for every field above.
6. Tests: the signer against the test vector, and this call against sandbox.

Before initiating a payout, please review our [Payout Best Practices](/guides/development-and-testing/go-live) guide to ensure successful transaction processing.
**Critical Warning:**
* Deposits to unsupported asset/blockchain pairs will be lost
* Deposits to incorrect addresses will be lost
* These losses are **permanent** and **non-recoverable**
