I want to ask how many the rate limiter for remote evaluation in Mix Panel? I can’t see the documentation. We got many error when hit Mix Panel with Code 429 (Too Many Request). The service have traffic 1000 RPM.
Based on the knowledge sources available, here are the relevant rate limits for Mixpanel APIs that could be causing your 429 errors:
Mixpanel Rate Limits
API | Rate Limit |
Ingestion API (/track or /import) | 2GB uncompressed JSON/min or ~30k events/second |
Query API | 60 queries/hour, max 5 concurrent queries |
Raw Data Export API | 60 queries/hour, 100 concurrent, 3 queries/second |
Lexicon Schemas API | 5 requests/minute |
GDPR API | 1 request/second |
Regarding "remote evaluation" specifically — the knowledge sources do not contain explicit documentation on a "remote evaluation" rate limit as a standalone feature. However, if you are referring to Feature Flags with remote evaluation, the docs mention it exists but do not specify a dedicated rate limit for it. [Feature Flags]
Recommendations to Handle 429 Errors
If you're hitting the Ingestion API at 1000 RPM, you are likely well within limits, but if you're hitting the Query API, 1000 RPM would far exceed the limit of 60 queries/hour. Here's what Mixpanel recommends:
Spread queries over a longer period to stay within hourly limits.
Consolidate multiple queries into a single query where possible.
Use exponential backoff with jitter — start with a 2s backoff, doubling up to 60s, with 1–5s of jitter. [Import Events]
Batch events — up to 2000 events per request to reduce total request count.
Use gzip compression (Content-Encoding: gzip) to reduce data size.
Next Steps
If you need a higher rate limit (e.g., for a one-time backfill or enterprise use case), Mixpanel recommends contacting your CSM or sales representative with your project_id and use case. [Import Events] Could you clarify which specific Mixpanel API endpoint you're calling? That would help pinpoint which rate limit applies to your situation.
