Channels - Postbase

A channel is one connected social account. Postbase publishes to the channels you select in the composer.

Supported platforms

Platform	Notes
X	Posts and threads. Bring-your-own app keys on every plan.
LinkedIn	Posts to your profile. Extra posts publish as a first comment.
Instagram	Business or Creator accounts (linked to a Facebook Page). Media required. On Postbase Cloud: coming soon, once Meta approves our app (use Notify me on the Channels page). Self-hosted: works with your own Meta app.
TikTok	Video or photo carousels only — no text-only posts. On Postbase Cloud, posts go out as private (only you can see them) until TikTok approves public posting.
YouTube	Video uploads.
Bluesky	Posts and threads (handle + app password).
Mastodon	Any instance — approve on your own server.

Connecting an account

Open Channels.
Pick a platform and choose Connect.
Authorize Postbase on the provider. Postbase only requests permission to publish — nothing else.

When you connect an account, Postbase captures its display name, avatar, and verified status so previews look like the real thing.

Managing channels

Connected accounts show under Connected, with the account’s avatar, handle, and status. Use Add another to connect a second account on the same platform, or Disconnect to remove one. Your plan sets how many channels you can connect — see Plans.
