X caption splitting
X has a 280-character limit. Most long-form captions exceed that. We now split the posting workflow: write your full caption for Instagram, TikTok, etc., then write (or auto-truncate) a separate version for X.
What changed
- New "X Caption" field in the Configure step
- Auto-truncation if you leave it blank
- Character counter with real-time validation
- Backend splits the API call — one for X, one for everything else
Technical detail
Under the hood, posts that target X alongside other platforms now generate two Postproxy API calls. We store both IDs and reconcile analytics from both sources automatically.
