eloomi can integrate and embed only secure websites (https://)
However, some websites cannot be embedded or integrated due to their IT policy or security settings, so the system is unable to pull the data and showcase it within eloomi.
Here is an article that might help you understand the type of x-frame options to use on your website in order to embed it into a module in eloomi: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options
You may also whitelist the eloomi domain from your web hosting in the Content Security Policy to allow the domain to be integrated through a module in eloomi.
Please note that any websites that require authentication like Sharepoint or Dropbox cannot be embedded.
