Third-Party API Integration

Stripe, Shopify, SendGrid, Twilio, OpenAI, Gemini. Webhooks, OAuth, API security.

SERVICE DETAILS

I integrate popular services and APIs with proper OAuth flows, API key rotation, webhook validation, and edge-case error handling. I build proper abstractions so you can switch providers later without refactoring code.

Key Benefits

Secure integration with proper error handling and retry logic.

Webhook setup with verification, rate limiting, and idempotency keys.

OAuth/JWT authentication flows for delegated access.

Provider abstraction—switch providers without breaking client code.

Monitoring & alerting on API failures.

The Process

1

API Documentation Review

Study API docs, auth flows, and rate limits.

2

Integration Implementation

Code SDK wrapper with proper error handling.

3

Webhook Setup

Configure webhooks with verification and event processing.

4

Testing & Monitoring

End-to-end testing and monitoring setup for API health.

FAQ

Do you build custom SDKs?

Sometimes I recommend using official SDKs. Custom wrappers are for custom logic or error handling needs.

What if the third party has an outage?

I implement circuit breaker patterns, fallback logic, and proper monitoring.

How do you handle rate limiting?

I use exponential backoff, request queuing, and caching to avoid hitting rate limits.

Initiate protocol. Establish connection. Let's build something loud.
