I am using Retrofit to make api calls in my android application. I have to submit a @Body of JSON
@GET(\"api/\")
void getData(@Body UserPostRequestBody request)
If the request body you need to send is not to complex you can also specify the query parametters as https://myserverdomain.com?somebody[property1]=value specifically on retrofit you define it like this:
Observable> someMethod(@Query("somebody[property1]") int property1);
that will work at least if you are requesting to a rails server hope this answer helps somebody
