From the ticket

Description

A subscription.updated webhook is being fired multiple times even though it has the same payload (happens during a downgrade/upgrade flow). This leads to duplicate notifications and potentially unintended side effects for webhook consumers.

Current Behavior

When a subscription is upgraded/downgraded (single update action), the subscription.updated webhook triggers multiple times. Consumers of the webhook receive duplicate events for a single change.

Expected Behavior

The subscription.updated webhook should only fire once per product downgrade/upgrade event. Consumers should receive a single webhook notification for each subscription change.
