Yes, there is a rate limit when updating user profiles via Mixpanel, including when using methods like mixpanel.people.set(...).
- The User Profile API allows you to send up to 2000 profile updates per request, and each individual update in the request can be up to 1 MB in size. If you need to update more profiles, you should break your requests into smaller batches to stay within these limits. These limits are typically encountered during bulk create or update operations [User Profile API Limits].
- Additionally, Mixpanel enforces a broader ingestion API rate limit of approximately 2GB of uncompressed JSON per minute or ~30,000 events per second, measured on a rolling 1-minute basis [Mixpanel API Rate Limits].
If you approach these limits, you may receive rate-limiting errors (HTTP 429). To avoid this, spread your updates over a longer period or batch them appropriately.
