How to create a Joomla API to work with an application?

Question

Joomla

What component can do this? To give the programmer making, a mobile application, full-featured access for development.
On the Internet, oddly enough, I did not find anything in the form of a component, or am I not looking correctly?
I was looking for a "Joomla API component" option and other options.

Answer 1

Most likely it means REST API. Here it depends on the component that is used. For example, for an online store on JoomShopping, you can use a native addon from developers. If for Joomla in general - see https://extensions.joomla.org/extension/rest-api/ Also here https://extensions.joomla.org/category/core-enhanc...

Answer 2

What do you want to give access to? The fact is that ALL Joomla consists of components, and the core itself is only queries to the database and similar elementary things, everything else consists of components, even what comes with the system by default, for example, "Materials" or a blog, is also a separate component, for example .
And so the API is here: https://api.joomla.org/
