Connected destinations are the foundation of everything else in Postly. If the right channels, pages, and targets are not connected cleanly, scheduling and analytics will never feel dependable.
What Postly connects
Depending on the platform and plan, a workspace can connect:
- social accounts
- child pages or channels under a parent account
Audience groups organize connected destinations for selection; they are not separate provider connections.
Use the connection flow for each supported platform. Available actions depend on the account type, permissions, and provider restrictions.
Recommended setup pattern
- Decide which workspace should own the destination.
- Connect the parent account through the official authorization flow.
- Select the specific pages, channels, or downstream targets that matter.
- Confirm the right operator or team can see them.
- Test with a simple draft before scheduling a full campaign.
Connect multiple accounts
Browser sign-in can determine which identity a platform offers to Postly. If the same account keeps appearing, check the signed-in identity before starting another connection.
- Keep Postly open in your browser.
- In another tab of the same browser, open the social platform and sign out of the account you do not want to connect.
- Sign in to the intended account on that platform.
- Return to Postly, choose the platform, and start the connection again.
- Select the intended identity if an account or channel chooser appears. Review permissions and confirm the destination in Postly before scheduling.
Repeat for each additional account. A separate browser profile can help keep client sign-ins separate; open Postly and the provider in that same profile.
Which platforms can be affected?
This can affect browser-based authorization for Facebook, Instagram, Threads, LinkedIn, Google Business Profile, YouTube, Pinterest, TikTok, X, and WhatsApp Business. The provider may offer an account chooser or reuse the browser session; behavior varies. An account chooser does not grant permission to every Page, channel, or location under that account.
Password, app-password, API-key, QR, and bot-based connections have their own instructions. Switching a browser sign-in does not replace those credentials.
My main YouTube channel is missing
Sign in with the Google account that owns the intended channel and select that channel when Google offers the choice. Invited YouTube Studio access does not include YouTube API access. For a Brand Account, check ownership and channel selection separately.
Read YouTube channel ownership and missing channels for the checklist and Google references.
Reconnect an account
If Postly asks you to reconnect, use Platform connections and authorize the intended account again. A provider can revoke access before a displayed expiry date. Check the page or channel selection after reconnecting, then review affected posts; reconnecting is not confirmation that a failed post has published.
You need the appropriate access to the actual destination, such as the Facebook Page, LinkedIn organization, YouTube channel, or Google Business Profile location. If a client owns the account, use Share Connection Link rather than requesting their password.
Common structure mistakes
Connecting everything into one workspace
This creates avoidable clutter and approval confusion. Keep clients, brands, or business units separated where possible.
Forgetting child pages
Some platforms expose additional pages or channels after the parent account is connected. Make sure the actual publishing target is connected, not just the parent identity.
A new Facebook Page is missing
Facebook permissions are tied to the Pages that were selected when Postly was authorized. A Page created or assigned later may not be added to that existing authorization automatically.
If you manage the Page in Facebook but cannot see it in Postly:
- Open Facebook Business integrations.
- Find Postly and select View and edit.
- Make sure Show a list of the Pages you manage is enabled.
- Under Pages, select every Page you want to use with Postly.
- Save the changes.
- Return to Connections in Postly, reconnect Facebook if necessary, and refresh the page list.
Postly can display and publish only to Pages for which Meta returns the required Page permissions and access token. See Facebook Pages Missing After Connection for the complete troubleshooting guide.
Assuming every channel behaves the same
Even when the connection is healthy, platform rules still differ. Use Postly validation and previews before a large campaign.
For developers and automations
In API and MCP flows, you should resolve the workspace first, then fetch connected targets before creating a post. That is the safest way to avoid publishing to the wrong destination.
