Paypal adaptive payment return url is calling twice

Question

I have implemented paypal adaptive payment method and using the web flow. After making a payment, when i explicitly clicks on return button, the return url calls twice but i

Answer 1

@jitendra, I had this same issue and found out that the paypal uses a server side script which redirects the user to the return url after a while and when we explicitly click on return button, then the paypal server script again hits the return url on its own thus we get two responses/hits on our return url.

We can over some this by checking/maintaining the no of responses which we get after the payments are made on paypal.

We can maintain this using cookies on client end or on server using sessions or something else similar.

Hope this helps well.
