# Unbind Binding

> <Note>This content applies to WaaS 1.0 only. We highly recommend that you upgrade to [WaaS 2.0](https://www.cobo.com/developers/v2/guides/overview/introduction).</Note> This endpoint allows users to unbind their broker account from their MPC Wallet account. It requires a POST request with a 'user_id' field in the request body. The response is a JSON object containing a 'statement_id' field which can be used to query the status of the unbinding process.
