How does the Opencart 3 API work?

Question

API

Hello. There was such a task, to make a bot for a social network that will be integrated with an online store. Actually, I have a couple of questions, I can’t find any guides or documentation on work anywhere. Interested in the following:
1. How to get a list of categories and links to them using the API?
2. How can I get a list of products and links to them using the API?
It is necessary that, for example, in php or js I could send a GET / POST request to the site, and receive JSON information in response. I've been googling for a couple of days, I can't figure out how it all works. Maybe someone came across? Can you tell me how to implement this, or at least what and where to read the documentation on working with the Opencart 3 API?
