Channels - Postbase

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

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.
