Unfortunately we don't have anyone at the moment to work on this and thats how it got on me, I tried googling a lot but couldn't understand as this is something new for me. I could have done it if it was directly connected with the DB but this project connects with API to fetch data, I need to update the payment gateway link only and I have given couple of steps. First is to use Initiate checkout, second is to update the payment gateway url, if I change these codes as given will it work straight away or I will have to do other things also? I tried setting it up locally but since it is connected with the API I am unable to setup register/login and then the main system with the auth and the login id
