Stripe fixture

`customer.subscription.created`

Fires when a new subscription is created on a customer. Note: this fires regardless of whether the subscription has started billing — check status carefully before granting access.

When does it fire?

A subscription is created via the Stripe API, Checkout, or the Dashboard. Includes trials (status: trialing) and immediate bills (status: active or incomplete).
