Many of the field properties have Text / Formula Builders (hammer icon). The “Insert a Function" selection has a section called, “Data Interchange”. The function that will allow you to best render your JSON is, “JSONVAL”.

{( JSONVAL({{json}}, 'jsonpath') )}

Returns the value from the given JSON for the given JSONPath query.
Note: The JSONPath '$.' prefix is not required.
e.g. JSONVAL({{myjson}}, 'resp.token’)

Attached is a screenshot of the list in the “Insert a Function” area for the Text/Formula Builder. 


When selecting a function you can hoover over it to show a description, explanation and some provide examples and reference links. Below is the information and reference links for each Data Interchange type.
