I will fix your ai app apis and webhooks
Ankit K
About this gig
Is your AI-built or vibe-coded app working except for the important parts?
Did you build an app with Lovable, Replit, Bolt, Cursor, Claude Code or another AI coding tool, but an API, webhook, authentication flow or third-party integration is failing?
I specialize in troubleshooting and fixing these issues without unnecessarily rebuilding your application.
I can help with:
- REST API integrations
- Webhook errors and failed event flows
- OAuth and authentication issues
- 401, 403, 404 and API errors
- CORS and environment configuration
- Frontend-to-backend integration
- Third-party API connections
- Database/API connectivity
- Data sync and automation issues
- AI-generated code bugs
My process is simple:
Reproduce -> Diagnose -> Fix Test
I focus on finding the actual root cause instead of applying temporary patches.
I work with APIs, webhooks, OAuth, backend systems and third-party integrations, so your AI-generated code gets an engineering-focused solution.
Please message me before ordering if the issue is complex, unclear, or involves multiple systems.
