Snippet preview with an access protected page

Our dev environment is hosted in cloudflare behind an access login wall. That seems to be a problem when testing out snippets, since they are not allowed past the access page and instead get redirected to the login page, which doesn't get shown because it's inside an iframe. Is there a way to allow the snippets thorough the access wall?

Snippets are executed after Access, so you'll have to bypass Access for requests towards iframe that is using Snippets (using headers, different URL, cookie or something else): https://developers.cloudflare.com/ruleset-engine/reference/phases-list/

The problem is in the snippets editor preview iframe. How can I control what headers the cloudflare dashboard is sending?

you can't remove or override our default headers, but you can add custom ones using Add headerAdd header in the preview
