Load UserLoop Surveys from Your Own Endpoint
UserLoop Surveys can now load a survey document that your page already has, or fetch one from an endpoint you control. This helps custom storefronts, landing pages, and other embeds avoid an extra request or serve localized documents.
Pass config to the UserLoop SDK to use a preloaded document. Or pass config_url and, if needed, language to fetch a document from your endpoint.
config takes priority when you provide both options. These settings apply to the survey ID used when you start the SDK; see the guide for refresh behavior, validation fallbacks, and safety notes.
