[RESOLVED] XMLHTTP GET, passing API parameters

Hi

When accessing a Web API using http(s) you can do it a couple of ways i gather, the simplest way is to just put a URL with all the parameters and send it.

The other way im trying to achieve it is to put all the parameters into the header and Body!??

so im looking at 'RocketReach.com' API, it says in the documentation that you can place the KEY into the 'Header' and the search criteria into the 'Body'

i cant find a 'Body' (a request one) in the xmlhttp object, am I getting this terribly wrong and by 'Body' it just wants me to put it into the URL?
