I'm looking for a skilled developer or Meta/Facebook API expert to help me complete and launch a Facebook App integration for my referral-based web platform, It's Buzzing.
What’s Built So Far:
Facebook App created and configured
Flask-based web app (hosted on Replit + Render)
OAuth flow partially implemented (login & redirect in place)
Instagram and Page posting routes drafted
Environment variables and permissions partially configured
What I Need Help With:
Debugging redirect URI errors and scope issues (instagram_business_basic, etc.)
Completing and testing OAuth flow with Facebook and Instagram
Handling access token storage and refresh logic
Enabling automatic post scheduling to FB and IG Pages
Preparing the app for Facebook App Review (usage documentation, test flow, permissions request)
Optimizing security (e.g., callback allowlists, cross-domain settings)
Ideal Skills:
Strong experience with Facebook Graph API + OAuth2
Familiar with Flask / Python (or can work alongside existing code)
Experience submitting apps for Meta App Review
Bonus: Instagram Business API and Meta Marketing integrations
