To know the status of the payment, you need to integrate the** Verify Payment** API as below. You need post the txnId sent by the v2/payments API in the txnId parameter.
HTTP Method: POST
Environment
| Test Environment | https://test.payu.in/v3/transaction |
| Production Environment | https://info.payu.in/v3/transaction |
Request parameters
Request header
| Parameter | Description |
|---|---|
| date | The current date and time. For example, format of the date is Wed, 28 Jun 2023 11:25:19 GMT. |
| authorization | The actual HMAC signature generated using the specified algorithm (sha512) and includes the hashed data. For more information, refer to authorization fields description. |
authorization fields description
| Field | Description |
|---|---|
| username | Represents the username or identifier for the client or merchant, for example smsplus. |
| algorithm | Use SHA512 algorithm for hashing and send this as header value. |
| headers | Specifies which headers have been used in generating the hash, for example date. |
| signature | The HMAC signature generated using the specified algorithm. For more information, refer to hashing algorithm. |
hashing algorithm
You must hash the request parameters using the following hash logic:
Hash logic: sha512(<Body data> + '|' + date + '|' + merchant_secret)
Where <Body data> contains the request body posted with the request.
Sample header code
var merchant_key = 'smsplus';
var merchant_secret = 'izF09TlpX4ZOwmf9MvXijwYsBPUmxYHD';
// date
var date = new Date();
date = date.toUTCString();
// authorization
var authorization = getAuthHeader(date);
function getAuthHeader(date) {
var AUTH_TYPE = 'sha512';
var data = isEmpty(request['data']) ? "" : request['data'];
var hash_string = data + '|' + date + '|' + merchant_secret;
var hash = CryptoJS.SHA512(hash_string).toString(CryptoJS.enc.Hex);
return `hmac username="${merchant_key}", algorithm="${AUTH_TYPE}", headers="date", signature="${hash}"`;
}Body parameters
| Parameter | Description | Example |
