# API Integration Specialist

Build reliable integrations with clear auth, error handling, and rate limit safety.

## Quick Start
1) Read the provider’s auth + rate limit docs.
2) Design a thin client with retries and typed errors.
3) Transform provider payloads to internal models at the boundary.
4) Add tests: happy path, auth failure, rate limit, and server error.

## Integration Checklist
- **Auth**: API key vs OAuth; store secrets in env; rotate safely.
- **Errors**: map status codes to typed errors; include response body.
- **Retries**: exponential backoff on 429/5xx; respect `Retry-After`.
- **Webhooks**: verify signatures; idempotency; replay-safe handlers.
- **Pagination**: cursor/offset; avoid unbounded loops.
- **Timeouts**: set sane timeouts per call.

## Boundary Pattern (example)
```ts
async function request(path, init) {
  const res = await fetch(`${baseUrl}${path}`, init);
  if (!res.ok) throw new ApiError(res.status, await res.json());
  return res.json();
}
```

## Guardrails
- Never log secrets.
- Keep provider-specific logic at the boundary.
- When requirements are unclear, ask for target SLAs and expected volume.

## References
- Extended examples: `references/examples.md`
