Does Frappe create REST APIs for doctype created in the custom Frappe app?

Hi @mayank_gupta:

Yes, Frappe creates automatically a REST API for every doctype, without any additional configuration.

Note that is case sensitive, so if your doctype is called “Article”, API call should be
library.localhost:8000/api/resource/Article

Edited: is your docype named “article” or “articles”?
