Depending on how you've setup your app, you may encounter a CORS error. It will look like this in your browser console:
In this case, you need to configure the right CORS headers to allow the domain app.forestadmin.com
to trigger an API call on your Application URL, which is a different domain name (e.g. localhost:3000 on development).
We use the Rack CORS Gem for this purpose.
