How to limit the format of django-rest-framework-api uploading(post method)

[Majid Am]

In fact, I need your help to limit the my api to upload

I only need Jason and excel formats(csv,xls,xlsl) on the server-side, but I did not find any code for that.

The second question is, what methods should I use to authenticate the user?

Here's a link that i use it code in my api

I will thank you :)
