# Testing with Sandbox If you are using the API for creating and modifying product specifications, on behalf of a *manufacturer*, it is recommended that you test your integration using our Sandbox system. The Sandbox provides a replica of the Erudus system for the purposes of testing API integrations. If you are updating product data using the API, it is essential that you test your applications before using them with the live system. Contact our support team to obtain access to the Sandbox system. --- # 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://developer.erudus.com/getting-started/testing-with-sandbox.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.
