In plain words
Cross-Origin Resource Sharing is the browser rule that decides which websites may call your API. On your system it is an explicit list — your own site and your dashboard — rather than the wide-open default.
CORS policy
A named list of the sites allowed to talk to your API. Anything else is refused by the browser before a single request is answered.
What it does for you
It stops another website from quietly using your API inside a visitor’s browser: reading your data, or acting as your logged-in customer on a page you do not control.
It is a small setting that is very often left open. On your system it is not.
What it gives your system
- Only your own sites can call your API from a browser
- Blocks other sites from acting as your logged-in customer
- Credentials sent only to origins on the list
- Reviewed whenever a new site or app is added
