Delete a visitor ID

Use this API to request the deletion of all data associated with a specific visitor ID.

Upon a request to delete data for a visitor ID,

• The data collected from the corresponding browser (or device) will be deleted asynchronously, typically within a few minutes. This data will no longer be available to identify this browser (or device). When the same browser (or device) revisits, it will receive a new visitor ID.
• The identification events made from this browser (or device) in the past 10 days are typically deleted within 24 hrs.
• The identification events made from this browser (or device) outside of the 10 days will be purged as per your data retention period.

The following timeline illustrates which events are deleted and which remain after a DELETE API request:

Day 1:  First visit from browser A. (Assigned visitor ID: VID1000)
Day 2:  Browser A revisits. (Assigned the same visitor ID: VID1000)
Day 13: Browser A revisits. (Assigned the same visitor ID: VID1000)
Day 14: Delete VID1000
Day 15: Browser A re-visits. (Assigned a different visitor ID: VID9999)
Day 15: GET /events/day-13 (Returns 404. The event is within the 10 days of deleting VID1000 and will have been deleted)
Day 16: GET /events/day-2 (Returns 200. The event is outside of the 10 days of deleting VID1000 and is still available)
