Api Integration Builder

This is a solid reference for building production-ready API integrations. It covers the practical stuff you actually hit: OAuth flows with token refresh, rate limiting strategies (both client-side and handling 429s), exponential backoff with jitter, and webhook handling. The code examples show real patterns like encrypting stored tokens, validating CSRF state, and distinguishing retryable from non-retryable errors. What I like is it assumes things will break and designs around that rather than just showing happy-path requests. Use this when you're connecting to Stripe, Slack, or any third-party API and want to avoid the common pitfalls around auth, retries, and rate limits that always seem obvious in retrospect.

API Integration Builder

Build reliable, maintainable integrations with third-party APIs.

Core Principles

Assume failure: APIs will go down, rate limits will hit, data will be inconsistent
Idempotency matters: Retries shouldn't cause duplicate actions
User experience first: Never show users "API Error 429"
Security always: Tokens are secrets, validate all data, assume malicious input
