F. How senangPay send the parameters to merchant’s shopping cart

1. The parameters will be send using GET method.

2. The parameters are sent to URL as configured in the return URL. Refer to Info required section.

 

G. How to generate the secure hash

1. The secure hash is generated by using HMAC hashing algorithm with SHA256 or md5 on a string consisting of (according to sequence):

  •  Secret Key
  • Detail
  • Amount
  • Order ID

2. For example if the values for the parameters are as below:

ItemDetail
Secret Key53-784
DetailShopping_cart_id_30
Amount24.50
Order ID56

3. So the string to be hash is $str = 53-784Shopping_cart_id_3024.5056 which will generate hash value as :

  • md5($str) => 0bde51ff340f110ab7331a902aa969e7
  • hash_hmac(‘SHA256′, $str, ’53-784’) => 74422328b44d30bf150fffbae89bbb42b885f9ac0960e2a3ddccc0cf9aa48e39

 

H. How to verify if the secure hash is correct

1. Merchant will need to generate the secure hash and compare the secure hash that was received from senangPay.

2. For example if the parameters received from senangPay are as below:

ItemDetail
status_id1
order_id56
transaction_id14363538840
msgPayment_was_successful

3. So the string to be hash is $str = 53-78415614363538840Payment_was_successful which will generate hash value as :

  • md5($str) => 69686562c29ad3f7955b1843a5c275ca
  • hash_hmac(‘SHA256′, $str, ’53-784’) => 4ca7837c6c4ddb5f6ba573ea701235b2d04bc6400d32787539e07aaf319eb70f

4. Now you need to compare the hash value that you have generated with the hash value sent from senangPay. If the value does not match then the data may have been tampered.
