API Integrations Done Right: A Pattern Guide
Most external integration bugs are design-time bugs. Request, retry, rate-limit, and error-handling patterns that make API integrations boring and reliable.

External APIs fail — that's the entire premise of integration engineering. Timeouts, retries, throttling, and idempotency aren't polish; they're the difference between code that works at 2am and a pager that fires at 2am.
The Four Defaults Every Call Needs
Every external request gets: a timeout (kill it before the app hangs), exponential backoff retries on transient failure, respect for the rate limit headers, and idempotency so retries don't double-create. Set these four once, as a library default, and integrations stop being a breeding ground for tickets. The same defaults underpin the prompts in the beginner API guide.
Treat the Response Shape as a Contract
Validate the payload structure on arrival — retries can't survive a schema change on the vendor side. Type the response early, log a friendly error otherwise, and keep the vendor docs link in the code comment. Solid contracts are the invisible half of API work.
Automate the Workflow You Keep Repeating
Integrations that grow into pipelines — move data, transform, notify — belong in an automation layer like n8n, where retries and error paths are visual and tested rather than reinvented per script. That's the connection the n8n guide draws between code-level and workflow-level automation.

Final Thoughts
API integrations are dependable when contracts and defaults do the heavy lifting: timeouts, backoff, rate limits, idempotency, and validation. Build the defaults once and integrations become boring — which is the goal.
