We need to consume a REST API to get a list of Ref data codes and description from an external system. The system is returning the code and description as JSON key and value respectively. In Pega, we need to map both the JSON key and value to Pega properties. Is there any OOTB rule which can be used to map the JSON keys in the response to Pega properties?

Sample response :

{     "values": {         "10": "Some description",         "11": "Some description2",         "01": "Some description3",         "02": "Some description4"     } }
