Invalid Checksum #81
Description
I am using this package, and my Laravel version is 10.0.
I have cross-checked all parameters and values, including the MID and Merchant Key, and everything seems correct.
I don’t understand why this error occurs.
When I click the pay button, the Paytm loading screen opens (the URL at this stage is processTransaction), but suddenly the URL changes to callback and shows an "Invalid Checksum" error.
