For making API calls i used the httpclient opject.
Soon i missed a lot of call types.
So, i copied the fphttpclient, named it the jahttpclient and created the missing methods.
Now i can make the calls i want.
But maybe someone else has the same problem, therefore i attached the unit to this post.
If someone tries/uses it, just let us know if it works for you too,
Or perhaps i was looking totally in the wrong direction.... and can someone correct me.
