You can add parameters to each REST Service Datasource connection. The types are:
  • URL
  • Path
  • Post

You can specify as many of these parameters on a connection in no particular order. Each requires a name and should have a default value.

Note: The following examples use the test URL https://qknpo561c0.execute-api.us-east-2.amazonaws.com/prod/ReimbursementRate/.

URL type

A URL parameter can specify the procedure code in the REST URL: 
https://TestURL?procedureCode=B5120ZZ
with the results: 
{"results":[{"procedureCode":"B5120ZZ","rates":
           [{"startDate":"2017-1-1","endDate":"2017-6-1","rate":0.85},
            {"startDate":"2017-6-2","endDate":"2017-12-31","rate":0.83}]}]}
The API Gateway entry point is: ReimbursementRate-API You can manually add more URL types.

Path type

A path parameter can specify the procedure code in the REST URL: 
https://TestURL/0313090
with the results: 
{"results":[{"procedureCode":"0313090","rates":
					You can manually add more Path types.        
					[{"startDate":"2017-1-1","endDate":"2017-12-31","rate":0.82
Note: Parameters that have default values are in the Ruleflow. Parameters that do not have default values are taken to be static parameter options that are not intended to take values; therefore, you cannot override their values.

Post type

A Post request does not include parameters as part of the URL, instead the parameters are data in the request document. Selecting Post parameter type changes how the REST connector makes its requests to the endpoint, so it is possible that any specified URL parameters will be ignored.
