About X on ShortSync

X moves fast, and posts that go out at the right moment get seen.

Post to X through its official API from the same upload as everything else, with its own 280-character caption. Share long videos, post to X Communities, add polls and the paid partnership label, and get warned before a video is over your limit.

The short version

Get your X posts out on time, with the right caption, community and labels, from one upload.

Frequently asked questions

Yes. ShortSync schedules video, image and text posts to X through its official API, on their own or from the same upload as your other platforms.
Videos can be up to 20 minutes and 8 GB, or 125 minutes and 16 GB with X Premium, in MP4 or MOV. Captions can be up to 280 characters.
Yes. Open the advanced settings and search for the community. You need to be a member first; if a community doesn't show up, join it on X and try again.
Yes, on text posts. Add 2 to 4 options of up to 25 characters each and choose a duration from 5 minutes to 7 days. Posts with an image or video can't have a poll, and X doesn't allow editing a poll after it's posted.
X charges for reading posts through its API, so ShortSync uses your own X developer app's Bearer Token for analytics, and X bills your developer account directly, about $0.005 per post. Add the key under Settings, Integrations, X analytics.
