I have had this terrible experience with paypal trying doing something simple like doing an API call.
In my opinion Paypal has the worst nightmare for any developer unlike for example stripe which is a peace of cake compared to it.
Anyway after search many websites excluding developers.paypal.com I found this great page
http://coding.smashingmagazine.com/2011/09/05/getting-started-with-the-paypal-api/
In a nutshell the page present a very simple code for calling any paypal api method.
After that you can go to https://developer.paypal.com/webapps/developer/docs/classic/api/ find the call you want (make sure you click on NVP not SOAP) Then you can make a call like this
