Expiration and Deletion Behavior of API Responses

Could you please clarify the expiration time of API Responses once they are created. Additionally, confirm whether deleting the last response using its ‘id’ will remove all associated responses or only the specific response ID provided.

Thanks

The expiration time for a “store”: true (the default) is 30 days.

You can confirm with API calls that issuing a DELETE https://api.openai.com/v1/responses/{response_id} against the latest response ID doesn’t traverse a tree of prior response IDs to delete anything else.
