Documented steps
Read rate headers on every response: X-Sentry-Rate-Limit-Limit, X-Sentry-Rate-Limit-Remaining, X-Sentry-Rate-Limit-Reset (epoch seconds) — docs: https://docs.sentry.io/api/ratelimits/
On HTTP 429: wait until the Reset timestamp (or Retry-After if present), then retry with exponential backoff + jitter, capped at ~3-5 attempts.
Watch the separate concurrency headers X-Sentry-Rate-Limit-ConcurrentLimit / ConcurrentRemaining — cap your parallel in-flight requests (a small pool, e.g. 5-10) so ConcurrentRemaining never hits 0.
Limits are fixed-window and PER ENDPOINT — a 429 on one endpoint doesn't mean all endpoints are throttled.
For change-detection use webhooks instead of polling — Sentry explicitly recommends this over API polling loops.
Known gotchas
Throttling is by caller identity, not token — rotating tokens does NOT raise your limit.
Concurrent-request limiting is independent of request-rate limiting: low RPS with high parallelism still 429s.
If Retry-After is absent, compute the wait from X-Sentry-Rate-Limit-Reset; if that's already past, retry immediately.
