Set connection link name from variable in invokeurl

Set connection link name from variable in invokeurl

Hi, guys.

How to set in parameter "connection" a variable, instead of a string.

  2. connectionLinkName = manager.get('connectionLinkName').toString();
  3. response = invokeurl [
  4.   url :"https://www.googleapis.com/calendar/v3/freeBusy"
  5.   type :POST
  6.   parameters:requestParams.toString()
  7.   connection:connectionLinkName
  8. ];
Returns an error


Thank you in advance
