I'm not clear from the linked issue what it is you're requesting. You can already get the ID of a generated sandbox which you can use to create a redirect, see https://codesandbox.io/docs/importing#define-without-render

I'm running into this too (just noticed it since a few days). This causes a "redirect" link on iframes using a src with a /define URL. Up until a few days / weeks ago, this was just showing the content of the target page of the redirect.

Sandbox: https://codesandbox.io/s/define-api-get-request-00f4f

This causes solutions using things similar to gatsby-remark-embedded-codesandbox to fail. See:

Looking into this now...

It should work as expected now again, I'm sorry for the inconvenience! This was a regression due to a recent CORS change.

Wow so fast Ives! 🚀💯 Looks good, back to normal! :)

@Rustin-Liu is it back to normal for you too? If so, I guess this can be closed. Looks like at least your demo links is working...

@karlhorky @CompuIves @garethx Thank for your supporting, it's working now.
