Why RESTful?

1 Rest ful reaponse is json object

2 restful  controller input data could be formdata or json object

3 restful methods get put post delete

Thanks your Feedback,

Current, In Controller, I use template from FuntionHelper to reaponse json object with my format json, apply all controllers. 

My format json same as: 

Code:

{"Status":200,"Msg":"Connected","Data":{"List":[],"Type":"Export"}}

I don't understant, different between my way vs RESTful (ci4 supports).

To return json results for Mobile App, Which solution should I apply?
