Configuring Stripe Webhooks

To enable automatic enrollment after payment:

Data Privacy

Course Flow includes an optional plugin telemetry feature.

When explicitly enabled by an administrator, the plugin may transmit limited, non-personal plugin metadata (such as site URL and plugin version) to the plugin author for diagnostic and compatibility purposes.

This feature is: – Disabled by default – Explicitly opt-in – Does not collect personal or user-identifiable data

The plugin functions fully without enabling this option.
