What kind of web content is supported to embed in a collection?

Question

Hi!

I tried to add a web page to my collection using embed, but I get an This content isn’t supported error.

Tried a different web page and it worked.

I also tried embedding the first web page within a StoryMap, and that gave me a card with a link to the page. When I tried the second web page within a StoryMap it shows displays as interactive content.

I assume pages that only can be "embedded" cards won't be possible to embed in a collection. But my question is how do I know wich web pages that can be embedded (for real not just as links/cards)? Is there any documentation on this?

If I for example could be able to influence the content of a web page, how would I make it embeddable?

Thanks, it would be great with documentation so we know what we have to comply with.

A web page must meet certain security requirements to be embedded in a collection or shown as a live embed in a story. For example, it must support https and allow embedding via the correct CORS headers, such as Access-Control-Allow-Origin.

We're working on some documentation on this that we'll try to make available early in 2022.
