When a Ramp transaction is created or changes state, Payward sends a POST request to the partner's configured webhook URL with transaction details and status information. #### Security All webhook requests include an `X-Signature` header containing an HMAC-SHA256 signature of the request body. Partners should verify this signature to ensure integrity of the request. Contact your Payward integration point of contact to securely exchange the HMAC secret key for signature verification. ##### Signature Verification 1. Extract the `X-Signature` header value 2. Compute HMAC-SHA256 of the raw request body using your webhook secret 3. Compare the computed signature with the `X-Signature` header value (hex-encoded) ```typescript import crypto from 'crypto'; // This function will return true/false if the signature matches const verifySignature = (signature: string, secret: string, body: string) => { const hash = crypto.createHmac('sha256', secret).update(body).digest('hex'); return (signature === hash); }; ``` #### Retry Behavior Payward will automatically retry failed webhook deliveries using exponential backoff. Partners should respond with HTTP 2xx status to acknowledge receipt. Non-2xx responses will trigger retries. #### Status Types The `status` field provides a simplified transaction state: - `new` - Transaction has been initiated - `paid` - Payment has been received - `pending` - Transaction is being processed - `completed` - Transaction successfully completed - `failed` - Transaction failed - `canceled` - Transaction was canceled parameters: - in: header name: X-Signature required: true description: HMAC-SHA256 signature of the request body (hex-encoded).
