> For the complete documentation index, see [llms.txt](https://docs.limio.com/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.limio.com/product/settings/security/content-security-policy-csp.md). # Content Security Policy (CSP) To allow use of external APIs inside custom components in Limio, in General Settings, or in Inject Code, you need to add trusted host to your shop's Content Security Policy (CSP). To do so, go to **Settings** > **Allowed Hosts** and **add the New Host**. Use a wildcard to set the domain more broadly (e.g. ). You should only add hosts that you trust and review this list periodically to remove any unused services.
--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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, and the optional `goal` query parameter: ``` GET https://docs.limio.com/product/settings/security/content-security-policy-csp.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.
