Approve Payout

The Approve Payout endpoint is used by the Merchant to explicitly approve a payout request before it is sent for processing. This step is required only when autoMerchantApproval = 0. Once approved, the payout transitions from a pending / queued state to processing, triggering the downstream fiat disbursement.

---

When to Use

Call this endpoint when:

• autoMerchantApproval = 0

• A payout has been created and is in a pending / awaiting approval state

• All required user inputs, KYC (where applicable), and validations are complete

---

Flow Context

1. Merchant creates a payout request

2. End user submits required details and completes KYC (if applicable)

3. Payout enters pending approval state

4. Merchant calls approvePayout (this endpoint)

5. Payout moves to processing

6. EUR is disbursed to beneficiary via Open Banking rails

7. Merchant’s USDC balance is debited accordingly

Flow outcome:

• The merchant initiates a transfer of USDC to the end user

• The end user completes the off-ramp flow via the hosted widget

• The corresponding fiat amount is made available to the end user via SEPA instant

• The merchant’s USDC balance is debited for the corresponding amount (including applicable fees, if any)

const axios = require('axios');
const crypto = require('crypto');

// Replace with your API Key and Secret
const apiKey = 'your-api-key';
const apiSecret = 'your-api-secret';

// Request body
const requestBody = {
    merchantOrderId: 'b73b73b-87wtbc-q36gbc-331n3' // please use a unique order id per request
}
// Convert request body to JSON
const raw = JSON.stringify(requestBody);

// Function to create HMAC SHA-256 signature
const createSignature = (secret, data) => {
    return crypto.createHmac('sha256', secret)
                 .update(data)
                 .digest('hex');
};

// Generate signature
const signature = createSignature(apiSecret, raw);

// Define headers
const headers = {
