Question

RESTful API

The point is this. I am a student and doing my internship. We were given the task of creating a prototype of an online store. Specifically, he screwed up on the basket. I came across some information on this topic, but the implementation is described there only on pure Django . I would like to ask for help from more experienced developers. Could you show the implementation on DRF . Those. how to use the functions indicated in the article below through the Rest API.
