E1:ORCH Pass entire JSON as Body of Connector Service request

Hi,

in the Orchestrator studio I have setup a connection to an external REST api which logs the recieved body of the call. When I create a service request using the connection and test it, I can hard code a JSON message in the "Body" section of the service request and I can add parameters to populate the body. But I cannot find a way of passing an entire JSOn structure into the body, when I try to send in e.g.

{

"my field" : "my value 1",

"my second field" : "my second value",

"some iterations" : [

{"iteration field" : "iteration value 1"},

{"iteration field" : "iteration value 2"}
