# Configure Webhooks and Triggers

The best way to check if your users are having an active subscription and activate the premium features accordingly is to **keep a copy of their current subscription state on your database**.

To do that you will need to configure webhooks that will be called when a subscription is created or updated on Stripe.

Those are **required** to support **shared subscriptions** and **subscription transfers**

[Customer Webhook](/getting-started/configure-webhooks-and-triggers/customer-webhook.md)
{% endcontent-ref %}

### The new user trigger

To handle new user already having a subscription, either because they were added to a shared subscription or because you added their subscription manually from the Stripe Dashboard

{% content-ref url="/pages/ymFeN4Leei5ShzA1u26k" %}
