I am wondering if anyone has some suggestions on the best way to go about credit card processing/validation on a form. Here is what I have thought about so far...
I want to be able to authorize the transaction before it's converted to a sale; so if the user inputs the wrong CC information, the form will be displayed with everything filled out still and they can make the correction.
Currently, I thought about putting a callback rule on it and setting a session variable to the transaction ID I get from an AUTH_ONLY. However, that causes problems if there is any false validation returns. It will show up on the users CC statement and temporarily take the funds from their account; essentially leaving 5 transactions if they submit the form 5 times with errors.
My next thought would be to just validate the form with the validation class and then validate the card after. (on the TRUE side of form validation) However, I am not really sure how to repopulate the form, etc if their CC is declined for any reason. Can anyone shed some light on this and give some input? Thank you!
