Connect X, LinkedIn, Instagram, Threads, and YouTube to any brand. Platform accounts are managed at the brand level — one brand can hold multiple accounts on the same platform.

LinkedIn uses separate OAuth credentials for personal profiles vs company pages. Both can be connected to the same brand simultaneously.

​
Connect a Platform Account

1

Initiate OAuth

Click a platform tile in Brand Settings → Connected Accounts. Autoposting generates a PKCE code verifier and redirects to the platform’s authorization page.
2

Grant permissions

Approve the requested scopes on the platform’s login page. You are redirected back to Autoposting with an authorization code.
3

Token stored securely

Autoposting exchanges the code for access and refresh tokens, fetches your profile info, and encrypts all credentials at rest. Tokens are never stored in plaintext.
Instagram requires a Business or Creator account linked to a Facebook Page. Personal Instagram accounts cannot be connected.

​
Token Refresh

Tokens are refreshed automatically 10 minutes before expiry — no manual action needed.

When a refresh fails (revoked access, password change), connected posts fail at validating. Reconnect the account from Brand Settings → Connected Accounts to clear the error.
