X has introduced a new API update that allows third-party apps to create posts up to 4,000 characters. This update aligns with the expanded posting limits announced in February last year and is available only to X Premium subscribers. These longer posts will appear with a "Show more" prompt in the X feed, allowing users to expand them beyond the original 280-character limit.

Key Points

• API Update: The new API v2 update enables external apps to facilitate long-form post creation.
• Post Length: Posts can now be up to 4,000 characters, a significant increase from the previous 280-character limit.
• Availability: This feature is exclusive to X Premium subscribers.
• Display: Expanded posts will show a "Show more" prompt to reveal the full content.
• X Articles: There is a distinction between the 4k posts and X Articles, which allow up to 100k characters but are not yet available via the API.
• Content Strategy: X is reducing the reach of link posts to encourage more direct content posting on the platform.

Future Implications

• User Engagement: The update might increase long-form post sharing, although its popularity remains uncertain.
• Platform Integration: Expect the expanded posting functionality to be integrated into various X management platforms soon.

This update is a step towards making X a more versatile platform, aligning with its broader vision of expanded functionalities.
