List members lookup
Members lookup group has two available endpoints. You are able to retrieve details on members of a specified List and see which Lists a user is a member of. These endpoints can be used to enable people to curate and organize new Lists based on the membership information.
There is a rate limit of 900 requests per 15 minutes when looking up member details and a limit of 75 requests per 15 minutes when looking up user memberships.
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 members
The manage List members endpoints allow you to add and remove members to 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 add a member to a List, and the DELETE method allows you to remove a member from a List. There is a user rate limit of 300 requests per 15 minutes for both endpoints.
Note that Lists cannot have more than 5,000 members.
Since you are making requests on behalf of a user with the 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).
To access these endpoints, you will need:
- An approved developer account.
- To authenticate using the keys and tokens from a developer App that is located within a Project.
