How to use express checkout using PayPal API in ASP.NET
+1
A:
Hi,
at first, you have to set account in the sandbox to do your tests :
https://developer.paypal.com/
The doc of aPI is here : https://cms.paypal.com/us/cgi-bin/?&cmd=_render-content&content_ID=developer/howto_api_reference
A possible way is to use :
SetExpressCheckout
GetExpressCheckoutDetails
DoExpressCheckoutPayment
You can store the TransactionId received and process : DoReferenceTransaction and DoCapture in order to set a recurring payment.
So, please set up your question explicitely and I can send you sample of code. The API is realy big.
