# Purchase Orders In the talque ticket shop users can buy tickets, or order free tickets. Each order contains one or more tickets and potentially voucher use. With the API you can list all orders, or read a particular order. Access to order data always requires a valid API client id & secret, and is never granted anonymously. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://talque.gitbook.io/public/json-api/purchase-orders.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
