Json Mapper
The Json Mapper action is one of the actions at your disposal to work with Json data. JSON Mapper enables you to extract a value from a JSON or a JSON array.
The action will be able to query/extract data from a JSON input using a JSONPath expression and save it to a variable.
You can use this website to test your JPath queries.
The action is used to filter the Json data that we will import in our process for future use.
Input Field 1: βInput JSONβ - Input your JSON object / Array or a data model.
Input Field 2: βQueryβ - The Input Jquery expression for obtaining the desired key value of your Json input.
Output Field1: βResultβ ( JSON Object value corresponding to the query)
