What you are doing looks correct.
The error is perhaps indicating that the PAYMENTREQUEST_0_AMT isn’t present. Try moving that element up from the end, or add something after it just to make sure that the last element isn’t being lost or corrupted. Also, verify that you aren’t missing any required elements (eg. PAYMENTREQUEST_0_CURRENCYCODE, PAYMENTREQUEST_0_ITEMAMT) There is nothing special needed in the header. The production code I have uses @URL with NVP. This was written before Web Call was implemented and Web Call is the preferred method going forward. If you can’t get it to work, email me the TAF that you have to support@. You can strip any sensitive data, I’m not going to POST to PayPal, but a utility I have that will show me the content of the post body.

I was able to execute successfully by submitting the NVP request via a browser and did receive a token from PayPal. Was Ben able to get NVP to work with the Web Call action? Do you know if anything is needed in the header tab? Or do I need to use @URL? Or do I need to use XML instead of NVP?

You use @URL or Webcall to begin the transaction with PayPal. They return a URL to you, which you redirect the user to by setting the httpheader and using a 302 redirect. You don’t need to include the @USERREFERENCE as long as the return url you provide to PayPal is at the same domain, this is because the cookie should still be active in the browser session. Including the @USERREFERENCEARGUMENT in the url won’t hurt, however. The most complex part of the process is building up the name value pairs and parsing the returns from paypal. Since some values are URLs, they need to be properly @URLENCODEd. PayPal offers a good sandbox environment to test the complete cycle, which is helpful. I know Ben Johansen is knowledgeable about this process if you are considering hiring a consultant. Robert From: Fogelson, Steve [mailto:[email protected]] Sent: Thursday, September 18, 2014 11:25 PM To: [email protected] <mailto:[email protected]> Subject: TeraScript-Talk: PayPal Express Checkout Has anyone put together a TeraScript app for PayPal Express Checkout? It appears that PayPal requires a direct url to their site with customer info including total purchase amount. The customer logs in to PayPal and approves purchase and payment. Then PayPal redirects back to the originating site. Wondering about the logic to accomplish this in TeraScript. Assuming I would use the Web Call action to start the transaction with PayPal, but not sure about the redirect back from PayPal. It may take the customer a while to do their business on PayPal. Should the PayPal redirect url include the <@USERREFERENCE>? Thanks for any insight you can provide to accomplish this.
