First things first, log in to your Xano account. Once you're in, head over to the Xano dashboard where you can see all your API configurations.

In the dashboard, find the "API" section and click on it. Then, pick the API endpoint you want to tweak the CORS settings for.

Now that you're in the API's configuration area, go to the "Docs" tab. This is where you'll find all the documentation and settings for your API endpoints.

Within the API documentation, hunt down the "CORS" settings. You'll usually find this under sections related to security or headers.

Flip the switch to enable CORS. It's typically a toggle or checkbox that you can turn on or off.

Enter the domains that are allowed to access your API in the "Allowed origins" section. You can list multiple domains separated by commas or use a wildcard (*) to allow all domains.

Specify the HTTP methods that are allowed for cross-origin requests. Common methods include GET, POST, PUT, DELETE, etc. Make sure you list all the methods you plan to support.

Define the HTTP headers that the client can use when making the actual request. Headers like Content-Type, Authorization, etc., can be specified based on your API needs.

For preflight requests, you can set configurations like how long the results can be cached by the client by setting the "Access-Control-Max-Age" header.

After you've configured all the CORS settings, don't forget to save the changes to apply them to your API endpoint.

Finally, test the API endpoint from a different origin to make sure the CORS settings are working as expected. Use tools like Postman or a frontend app hosted on a different domain to validate the settings.

This step-by-step guide ensures the correct configuration of CORS settings in Xano.
