Introduction

List follows lookup

List follows lookup group has two available endpoints. You are able to retrieve details on followers of a specified List and get data on which Lists a user follows. These endpoints can be used to enable people to curate and organize Tweets based on what type of Lists other users are following.

There is a rate limit of 180 requests per 15 minutes when looking up followers of a List and a limit of 15 requests per 15 minutes when looking up what Lists a user follows.

You can use OAuth 1.0a User Context, App only, or OAuth 2.0 Authorization Code with PKCE to authenticate your requests to this endpoint. 
 

Manage List follows

The manage List follows endpoints allow you to follow and unfollow a List on behalf of an authenticated user. For these endpoints, there are two methods available: POST and DELETE. The POST method allows you to follow a List, and the DELETE method allows you to delete a List. There is a user rate limit of 50 requests per 15 minutes for both endpoints.

Since you are making requests on behalf of a user with these endpoints, you must authenticate them with either OAuth 1.0a User Context or OAuth 2.0 Authorization Code with PKCE, and use the user Access Tokens associated with a user that has authorized your App, which can be generated using the 3-legged OAuth flow (OAuth 1.0a) or the Authorization Code with PKCE grant flow (OAuth 2.0).
