HTTP Method: DELETE

Environment


Test	https://test.payu.in/storecard/card/v1
Production	https://info.payu.in/storecard/card/v1

Request parameters

Authentication 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 table below.

authorization fields description

Parameter	Description
username	Represents the username or identifier for the client or merchant, in this case, it's "smsplus".
algorithm	Use SHA512 algorithm for hashing and send this as header value.
headers	Specifies which headers have been used in generating the hash. In this case, only the "date" header is used.
signature	The actual HMAC signature generated using the specified algorithm (sha512) and includes the hashed data. For more information, refer to hashing algorithm.

hashing algorithm

You must hash the request parameters using the following hash logic:

sha512(<Body data> + '|' + date + '|' + merchant_secret}

Where, <Body data> contains the request Body posted with the request.

Sample authorization header code

var merchant_key = 'smsplus';
var merchant_secret = 'izF09TlpX4ZOwmf9MvXijwYsBPUmxYHD';

// date
var date = new Date();
// var date = "Wed, 28 Jun 2023 11:25:19 GMT";
date = date.toUTCString();

// authorization
var authorization = getAuthHeader(date);
console.log(authorization);

function getAuthHeader(date) {
var AUTH_TYPE = 'sha512';
var data = isEmpty(request['data'])?"":request['data'];
var hash_string = data + '|' + date + '|' + merchant_secret;
console.log("Hash String is ", hash_string);
var hash = CryptoJS.SHA512(hash_string).toString(CryptoJS.enc.Hex);
var authHeader = 'hmac username="' + merchant_key + '", ' + 'algorithm="' + AUTH_TYPE + '", headers="date", signature="' + hash + '"'
return authHeader;
}

pm.environment.set('date', date);
pm.environment.set('authorization', authorization);
pm.environment.set('merchant_key',merchant_key);
pm.environment.set('merchant_secret',merchant_secret);

function isEmpty(obj) {
for(var key in obj) {
if(obj.hasOwnProperty(key))
return false;
}
return true;
}
