Hey there,

I am trying to integrate PayPal  using a Live account. I am trying to retrieve token using SetExpressCheckout then Its redirecting again on same Checkout page & not getting any error on page.

But I am using another Direct Payment method API, then Its  getting 10002 error. Below are the screenshots . Kindly help.

Please let me know if you need any further Information.

Looking forward  your cooperation and assist me where I am lacking.

Thanks
