+You don't need to explicitely pass `WORKING_KEY`, `ACCESS_CODE`, `MERCHANT_CODE`, `REDIRECT_URL`, `CANCEL_URL` in the form data for any of the method i.e. `Iframe` or `seemless`.

 ## To encrypt the data
 
 `form_data` is the post request body which is a dictionary of the related data for the payment. You don't need to pass the Merchant ID though. Since we have already intiated the package with the correct `MERCHANT_CODE`. `encrypt()` method return the encrypted string that can be ussed directly in the Iframe rendering.
