What data is sent and when
When you generate alt text (individually, in bulk, or via the “Test Connection” button), the plugin sends the public URL of each image to the Filestack Caption API.
The API endpoint used is https://cdn.filestackcontent.com. Your configured API Key, Policy, and Signature are included in the request URL for authentication.
No other user data or site data is transmitted.
