Best way to deal with JSON payloads.

Hello All:

I have to call a REST web service which returns data in JSON format, and I have to look for some fields and display them in the web page.

I tried JSONExecute( ) but I got "send error"... I tried with RESTSend() and it worked fine.
Now, my question is; what is the best way to deal with the JSON payload? Should I convert it to Variant or a structure? Should I use Deserialization?

Thanks for sharing your experiences.

Regards;
Gus
