Data retention and deletion

Use DELETE /surveys/{surveyId}/sessions/by-reference/{reference} when the source platform deletes a response or when your retention workflow requires removal. The operation removes the matching behavioral events, session summaries, and scores asynchronously.

Poll the deletion result until it is completed or failed. Ramon maintains deletion tombstones for pending, completed, and failed records so delayed events do not recreate removed data. Your source platform remains responsible for retention policy, user requests, and any required audit workflow.
