Hi,
Check out this documentation and the movie: https://docs.mendix.com/refguide/consumed-rest-services
It will explain the basics of REST with Mendix
Hi,
To pass JSON to a REST API via a POST method, you have to use export mapping instead of import mapping for the GET method, since you are 'translating' mendix objects to JSON. Check this documentation on how to do that: https://docs.mendix.com/refguide/export-mappings
Hope this helps
