How can I use Adyen to make a 0$ transaction to save the users information, a recurring contract so to speak. I can only do transactions that aren't 0$.
Whenever I do a transaction of 0$, go to the page, click a payment option. I get the error: Error: Invalid Amount Specified
.
What I need is: Save users payment information i.e creditcard info in Adyen. Use these payment details to send a payment on a different time.
