A shortcut for wallets that hold **both** the approver and release-signer roles. {% hint style="info" %} The reference below is generated from the **live API spec** ā€” if anything on this page disagrees with it, the reference wins. {% endhint %} ## Endpoint ## Approve milestones AND release their funds in a single atomic tx > Shortcut for wallets that hold both the approver and release-signer roles.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.trustlesswork.com/trustless-work/v2-en/api-rest/deploy-1/approve-and-release-milestones.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
