I'd like to deply the My Domain feature. It's currently in testing mode--admins can see it, redirects are happening, etc but it's not deployed to users.
The biggest concern I have is API endpoints that we currently provide to partners. If they're using our APIs, will this affect the endpoint URLs, or would they just follow the redirect safely?
Is there an easy way to see if we have anything internally hardcoded with an na1 (custom buttons, vf pages, links, email templates, etc)?
