We enforce a rate limit on our API to ensure the integrity of our system as well as prevent a single project from monopolizing the available resources for other projects. These rate limits are scope per project.

Getting a 429 response code from our API means that you have reached our rate-limit.

The rate limits are as follows:

Ingestion API

2GB of uncompressed JSON/minute or ~30k events per second, measured on a rolling 1 minute basis. Please click here for more details.

Query API

A maximum of 5 concurrent queries and 60 queries per hour.

Raw Data Export API

A maximum of 100 concurrent queries, 60 queries per hour, and 3 queries per second.

Lexicon Schemas API

A maximum of 5 requests per minute, under 4000 events and properties updated in each minute, and less than 3000 total truncations/deletions per request.

You can reduce rate-limiting errors using one of the two approaches:

Spread your queries out over a longer period of time.
Consolidate multiple queries into a single query (for example, multiple queries filtering on a single property may be combined into a single segmentation query).
