I’d like to know whether or not it is possible for deploy previews to use my custom domain that I have set up with Netlify DNS. Having our deploy previews on our own domain is very important since our authentication system will only work on trusted domains, and we can’t add the netlify domain as a trusted domain since anyone can create a website on it. I have looked through similar topics but the answer hasn’t been very clear, someone suggested using branch deploys, which I did get working but the process of adding a subdomain for the branch is manual which is a deal breaker. And if we’re using branch deploys instead of deploy previews we would not be able to take full advantage of Netlify’s feedback tools like the Netlify drawer, right?
At the moment no, deploy previews are only available on Netlify domains.
You could setup another site which you could use to proxy to the latest deploy. Depending on your setup, this might or might not be a possible solution.
+1 on this feature - we have a lot of 3rd party integrations that require authorizing domains and we can’t authorize *.netlify.app. Similarly, we have a sanity studio deployed that requires hosted instances to be authorized for CORS (and credential forwarding) - we cannot grant this access to all *.netlify.app hostnames. almost a year later, anything further to report here?
