send a custom argument to url link

[platonic1]

Using the link https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=G27KSP4QVCQ48&custom=UI... Am I supposed to get the custom argument on IPN? If no. Is it possible to send a custom argument that would be sent to IPN and if so, how is it done?

Thanks

Hello,

Yes, using the "custom" variable you can pass a unique value and have that returned within IPN data. For a "hosted" or "saved button", edit the code for the button and go to "step 3" and in the section "advanced variables" add the following "custom=12345" (without quotes)

Save the button, copy the code and add to a webpage and test. You can check IPN history within your account to view the IPN data contained within the IPN message, by clicking on the "message id" value.

So there is no way to add that custom argument, a dynamic value?

Thanks
