# 5. Test Embed Configuration Before integrating Embed you might want to check that all the settings are correct and the iframe looks as expected for an end user. ### Local testing In order to open an Embed in a local html page (i.e. where the URL is a file path), you need to specify `file://*` in the **allowed domains**. ### Testing on Google Sites One can also test embedding the iframe in Google Sites. In order to allow it to open there the **allowed domains** need to be set to: ``` sites.google.com www.gstatic.com *.googleusercontent.com ``` {% hint style="danger" %} The **allowed domains** settings above should be used solely during the testing phase, where it's absolutely needed. Remove it from the allowed domains once you're going to your staging or production environment as it adds a potential security risk. {% endhint %} --- # 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.locoia.com/embed-white-label-portal/embed-admin-setup/5.-testing.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.
