Resilience

Every outbound call needs a timeout

The default HttpClient timeout is 100 seconds, far longer than anyone waiting on you. Set timeouts deliberately, layer them so they make sense together, and pass cancellation through.

Circuit breakers stop you hammering a failing service

Retries help with brief failures. When a dependency is down for minutes, retries just pile on. A circuit breaker notices and fails fast until it recovers.

Handling 429 Too Many Requests

When an API says you're sending too much, it usually tells you how long to wait. Respect that, slow yourself down, and your integration stops getting throttled.

Retries with exponential backoff and jitter

Retrying a failed call is easy. Retrying it without making the outage worse takes backoff, jitter and some care about which requests are safe to repeat.
