I am having trouble getting a transaction to complete using the PayPal Express Checkout IPN. Right now I am testing everything in Sandbox mode.
Using SetExpressCheckout, I am able to generate a token and am being redirected to the first payment page:
When I enter my login information, I am prompted to click the button to continue towards confirming the payment:
When I click Continue on that page, I am then redirected back to the first page. It is just an endless loop of these two pages.
My login information is correct and the sandbox account has enough funds in it to complete the sale. All of the buyer and purchase information is being sent correctly. I just can't figure out why I can't get past this step.
Any ideas?
