Aggregate events

The aggregation API lets you compute aggregated results on events, such as getting the count of all Events in a project, checking different descriptions of events in your project, etc.

Aggregate filtering

Filter (filter & advancedFilter) data for aggregates

Filters behave the same way as for the Filter events endpoint. In text properties, the values are aggregated in a case-insensitive manner.

aggregateFilter to filter aggregate results

aggregateFilter works similarly to advancedFilter but always applies to aggregate properties. For instance, in an aggregation for the source property, only the values (aka buckets) of the source property can be filtered out.

Request throttling

This endpoint is meant for data analytics/exploration usage and is not suitable for high load data retrieval usage.
The Aggregates endpoint, as with all endpoints in the Events API, is subject to a request budget that applies limits to both request rate and concurrency. Please check Events resource description for more information.
