Common Issues general

Third-Party Integration Not Working (APIs, Webhooks, OAuth)

Your app integrates with a third-party service (Google, Stripe, Twilio, OpenAI, etc.) and the integration stopped working or never worked properly. API calls fail, webhooks don't fire, or OAuth login redirects go nowhere.

Common Causes

  • API keys expired, revoked, or not set in production
  • Webhook URL points to localhost or an old deployment URL
  • OAuth redirect URIs don't match the actual app URL
  • Rate limits hit — the API is blocking requests because you're making too many
  • API version changed and the integration code uses an outdated version

How to Fix It

  1. Check the third-party service's dashboard for error logs or failed requests
  2. Verify all API keys are current and set in your production environment
  3. Update webhook URLs to point to your production domain
  4. Check OAuth redirect URIs in the third-party service's settings
  5. Test the API calls directly (using Postman or curl) to isolate the issue

Luca Liberati Luca Liberati I work on monoliths and microservices, backends and frontends, manage K8s clusters and love to design apps architecture Matthew Jordan Matthew Jordan I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job. Mehdi Ben Haddou Mehdi Ben Haddou - Founder of Chessigma (1M+ users) & many small projects - ex Founding Engineer @Uplane (YC F25) - ex Software Engineer @Amazon and @Booking.com Caio Rodrigues Caio Rodrigues I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures. I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations. Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization. I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems. My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.** Franck Plazanet Franck Plazanet I am a Strategic Engineering Leader with over 8 years of experience building high-availability enterprise systems and scaling high-performing technical teams.

While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing. My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.

Frequently Asked Questions

The integration worked before. Why did it stop?

API keys might have expired, the service might have updated their API version, or your webhook URL might have changed after a redeployment.

Can a developer set up the integration properly?

Yes. A developer can debug the failing integration, update API configurations, and ensure everything is properly connected.
