I would like to propose a feature enhancement for Lago that involves the introduction of webhooks to handle subscription renewal events. Use Cases: Allow applications to notify users via email before their subscription renews. Example: "Your subscription will renew soon. If you wish to change or cancel your plan, you can do so now." For long-term plans (e.g., annual subscriptions), there is often a need to adjust usage metrics before the renewal period begins. Example Scenario: A user has prepaid for 100 seats but plans to reduce usage to 80 for the next billing cycle. Refunds or adjustments aren't applicable during the current billing period since they’ve already paid for 100 seats. Before renewal, we would like to update the usage metrics to reflect the reduced seat count for the upcoming cycle. In some cases, we may want to perform specific actions immediately after the renewal event, such as updating internal records or triggering follow-up workflows.
