Fix Social Media Publishing Errors

Job ID: 40247132

Budget: $10 – $30 USD

I have a custom platform that already publishes to X.com, yet every attempt to push the same content to Instagram, Facebook, and LinkedIn fails with publishing-permissions errors. All required developer apps are set up and linked, but something in the workflow likely tied to token scopes, app review settings, or endpoint requirements is blocking the final post action.

I need someone who knows these APIs inside out to:
• Trace the exact permission or scope failure for each network
• Implement the code or settings changes that clear the error
• Prove the fix by successfully posting test content from the platform to all three accounts

Please bring recent experience with Meta Graph API, LinkedIn v2 API, OAuth flow debugging, and webhook logging. Once everything is live and verified, a brief summary of what was changed will wrap the job.
