What is the process for enabling users of my WIX website to upload files to my Google storage buckets?

edit

The process for enabling users of your WIX website to upload files to your Google storage buckets involves several steps:

1. Create a Google Cloud Storage bucket for your website files.
2. Set the appropriate permissions and access control to the bucket to allow external uploads.
3. Generate the necessary credentials (such as a service account key) to access the bucket programmatically.
4. Create an HTML form that allows users to upload files to the bucket, and specify the necessary credentials and endpoint url in the form action.
5. Use a backend language (such as Node.js or Python) to write a server-side endpoint that handles the file uploads and sends them to your storage bucket.
6. Secure the server-side endpoint to prevent unauthorized access or misuse of the uploading functionality.

If you're unfamiliar with any of these steps, it's recommended to consult the relevant documentation or seek the assistance of a specialist or developer to ensure proper implementation.
