Comparing X API’s timelines endpoints
The v2 reverse chronological timeline, user Posts timeline, and user mention timeline endpoints replace the v1.1 statuses/home_timeline, v1.1 statuses/user_timeline, and v1.1 statuses/mentions_timeline endpoints respectively. If you have code, apps, or tools that use an older version of this endpoint and are considering migrating to the newer X API v2 endpoint, then this guide is for you. For a more in-depth migration guide see Standard v1.1 migration to X API v2. This page contains three comparison tables:- Reverse chronological home timeline
- User Post timeline
- User mention timeline
