Transient retry

Technical Preview

The Go SDK is a technical preview. Its API surface may still evolve and changes may not follow semantic versioning. Pin an exact version if you need stability.

Retries are layered below backpressure in the http.RoundTripper chain, so a retried request is still subject to the concurrency limiter and cannot amplify a load spike:

// Transient failures (429, 502, 503, 504 and network errors) are retried with
// exponential backoff and full jitter. Non-transient 4xx are never retried.
client, err := camunda.New(
	camunda.WithRetry(camunda.RetryConfig{
		MaxAttempts: 5,
		BaseDelay:   100 * time.Millisecond,
		MaxDelay:    5 * time.Second,
	}),
)

Only transient failures are retried. A 400, 403, or 404 is returned to you immediately — retrying a request the server has definitively rejected wastes time and hides the real error.
