Callback handler
The callback will be received from Plutu when the transaction is completed or canceled. This gives a Merchant better control of how the transaction is processed on the Merchant's side. This is useful e.g. when you want to mark an order as paid, update your shop's inventory, or add appropriate records to Merchant’s internal accounting system.
Callback response parameters:
The callback is called with HTTP GET and with the same query string parameters as in the redirect

hashed
Hash message authorization code (HMAC) is used to verify both the data integrity and the authorization of a message.
SHA-256 HMAC is calculated as follows:
The SHA-256 HMAC calculation includes all response query string parameters and key-value pairs except the “hashed” parameter.
Create an SHA-256 HMAC of the resultant string using the secret key created in the Plutu account, convert it to uppercase, and compare it with the “hashed” parameter received in the callback.
