Question
When using the Segment Profile API Events endpoint with a start parameter, why are events with timestamps earlier than the specified start date included in the results?
Product
Segment
Environment
Segment Console
Answer
The Profile API filters events based on the received_at field, which is when Segment ingested the event, not the timestamp field that indicates when the event occurred. Events with earlier timestamps but later ingestion dates will be included if their received_at value is after the specified start date.
