I am new to authorize.net, I have integrate authorize.net with my project it was great experience to use authorize.net for better performance and great documentation at all. But at last have necessary to get one thing.
While already registered user come to site and purchase something than how to get his credit-card information from authorize.net, Because user want to change his credit card information.
- I wan to know how to get credit - card information about already registered user in site ?
- How to update the credit card information from there ?
Thankful to all
