CB Auto Action PHP

What is the proper way (configuration) to do a POST or GET using the request method in CB Auto Actions?
I need to send the user first name for example. Something like this:

mywebsite.com/integration.php?&name= [name]

but it doesn't work. Also the return option is "show" but doesn't show anything.

Same way you would if you were using CURL to make an HTTP call. For POST you specify the values in the textarea as instructed by the description. If making an HTTPS call be sure CURL and EXEC is available. If making an HTTP call ensure fopen is available. Set "Debug" to "Show" and it'll vardump the snoopy object to see why the request may have failed (ensure debug mode and maximum error reporting is configured in global configuration). If nothing outputs with debug then your HTTP request is never happening (check that your conditionals and access are valid).
