# JSONP support When sending a call from a server in a different domain, you can use JSONP (JavaScript Object Notation with Padding). Most browsers enforce a same-origin policy for asynchronous data requests, sometimes called AJAX. Under the same-origin policy, a browser serving a page from server.example.com could not normally request a document from api.digitalriver.com. Some exceptions are provided–most browsers make an exception for HTML. --- # 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://docs.digitalriver.com/commerce-api-references/commerce-api-reference-guide/api-structure/jsonp-support.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.
