# Delete an agent session

`DELETE /agents/sessions/{session_id}`

## Request

- Base URL: `https://api.openai.com/v1`
- URL: `https://api.openai.com/v1/agents/sessions/{session_id}`
- Auth: HTTP bearer

Removes a managed agent session from the public API and returns a deletion confirmation. If backend execution has ended, deletion can cancel a still-open public turn and abandon unpublished outputs. Running execution must be cancelled first. Physical cleanup may continue asynchronously. See [managing sessions](https://developers.openai.com/api/docs/guides/agents-api/sessions/manage).

## Response `200`

- DeletedSessionResource: A Managed Agents session removed from the public API. Physical cleanup may continue asynchronously.
  - `id` string, required: The ID of the deleted session.
  - `object` 'agent.session.deleted', required: The object type. Always `agent.session.deleted`.
  - `deleted` boolean, required: Whether the session has been removed from the public API. Always `true`. Physical cleanup may still be in progress.
