I have been using the sandbox account and the aim of our project is to charge our customer when they subscribe to any of our services like $9.99 per month etc. My question here is when I use the Class AuthorizeCreditCard to charge the account for a certain amount then how is that amount charged to the customer? Is it a direct charge or will there be any OTP type to be received by the card holder for that particular amount?
And How that amount will be submitted to my account later?
Also tell me please which class is best for my requirement from the below list which I got from github:
