Will this script that shows the total amount of CMS items in a specific Webflow collection and renders it to a specified text element with class ".users" work on Webflow despite the CORS error I am receiving?

Unfortunately, the CORS (Cross-Origin Resource Sharing) error you are experiencing is not specific to Webflow but rather a security measure implemented by web browsers. It restricts resource sharing between different domains to protect users' privacy and security.

When making requests from a script, the web browser enforces the same-origin policy, allowing requests only from the same origin. If the domain of the script you are executing and the domain of the requested resource (in this case, the Webflow CMS API) are different, the browser will block the request and display a CORS error.

To resolve this issue, you have a couple of options:

1. Use a server-side script: Instead of making the API request directly from the client-side script, you can set up a server-side script that acts as a proxy. The client-side script can make a request to your server-side script, which then forwards the request to the Webflow CMS API. Since the server-side script is executed on the same domain/server, it will bypass the CORS restrictions.

2. Enable CORS on the server: If you have control over the server serving the Webflow CMS API, you can configure it to include the necessary CORS headers in the API responses. By allowing cross-origin requests explicitly on the server, the browser will no longer block the requests.

3. Use Webflow's API Embed feature: If you are using the Webflow CMS API within a Webflow project, you can utilize Webflow's built-in API Embed feature. This allows you to bypass the CORS issue by making the API request directly from the Webflow project's server-side environment.

It's essential to consider the security implications of bypassing CORS restrictions and ensure that you implement proper security measures in your server-side script or server configuration to prevent unauthorized access.

Remember, these solutions might require technical expertise and depend on your specific use case and access to server-side resources.
