REST service is not receiving input data

I have a REST service that implements GET and PUT. The PUT function works fine; it takes a page property of data in the Message Parameters area, inserts the data into a data type and returns “Data added successfully”. The GET does NOT work - it takes one property in the Query string area; I have confirmed by writing a log message from the service activity that no value is being received. I am using Map to Clipboard to process the input on the service and the service activity relies on the primary page to access the property. The service and connector are on the same cloud instance, except that they are built in different parent class structures (service is in MyCo-xx and connector is in ABC-xx).

@SalS0919 I created v2 of the service to parameterize the URI; I am able to use the parameter in the GET and it works as expected. So now I pass a parameter in the URI for the GET method, and I use a page property in the Message Data area to pass the values for the POST. I would like to call this service in a consistent fashion, using a scalar for the GET in in the Query String area along with the page in the message data area for the POST.
