If it can be done without API then even better. I need 2 separate scripts from you and i'll add it to myself to my site.
1)will have a link or a button when clicked user is taking to paypal to pay. He enters his payment info but paypal doesnt charge it only authorize the transaction. And he is taking back to my site.
2)second script i will run about 5-10 days later to charge the person the amount he agreed to pay before.
No design, just simple 2 scripts that i will insert into my own scripts.
