authorization fields description

Field	Description
username	Represents the username or identifier for the client or merchant, in this case, it's "smsplus".
algorithm	Indicates the hashing algorithm used for the HMAC signature. Here, it is set to "sha512".
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 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;
}
