Connect your source account
Your source account is the one you keep posting on, as usual. Pick it under "Where do you post first?" when you sign up, or on the Bridge page later, and sign in to that platform to connect it. Post Once can read from Instagram, Facebook Pages, Threads and X.
The source account is where you keep posting, in that platform’s own app. Post Once never posts there. It watches it for new posts and reposts them to your other accounts. New to all this? Start with how Post Once works.
Which accounts can be a source?
| Platform | What Post Once picks up | Notes |
|---|---|---|
| Reels and videos, photos, carousels, Stories | Needs a Business or Creator account. See repost from Instagram. | |
| Videos and Reels, photos and albums, Stories | A Facebook Page, not a personal profile. See repost from Facebook. | |
| Threads | Videos, photos and carousels | See repost from Threads. |
| X | Videos and photos | Replies, reposts and text-only posts are skipped. See repost from X. |

Frequently asked questions
Can YouTube be my source account?
No. YouTube is a destination only. Post Once can read new posts from Instagram, Facebook Pages, Threads and X.
Can I have more than one source account?
Each bridge has one source. To repost from a second account, make a second bridge. Free and Solo include 1 bridge, Studio 3 and Agency as many as you need. See bridges.
Will connecting repost everything I posted before?
No. Only posts published after you connect are reposted on their own. Older ones appear in Your posts, where you can post any of them by hand.
