Get JSON Details from the Last REST Operation

See more REST Examples

Demonstrates Rest.GetLastJsonData, which copies operation-specific diagnostic or result information from the most recently completed method into a JsonObject. Many methods produce no JSON, in which case the object is empty.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.

Background. Some Chilkat operations expose additional structured information as JSON. GetLastJsonData provides access to that information after an operation completes.
