The question:
I wan to use REST API for saving and fetch setting of my plugin in wp-admin. Is it a good practice? Or is it better to use admin-ajax for this?
The Solutions:
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
Method 1
You can and should totally do this in my opinion. Especially if you have a RESTful case. I personally only use admin-ajax for very simple things to almost no more.
