# subscriber.enrolled

> A customer has been enrolled into a subscription plan. The first invoice has been created and is awaiting payment.

## When it fires

Immediately after a subscriber is enrolled — either via the [Enroll Subscriber API](/api-reference/subscriptions/enroll) or from the merchant dashboard. The subscriber's status is `pending` and a first invoice has already been created.

***

## What to do

* Send the customer a **welcome email** with payment instructions
* Show a "complete your subscription setup" prompt in your UI if they're mid-onboarding
* **Do not provision access yet** — the customer has not paid

<Warning>
  Do not grant product access on `subscriber.enrolled`. Wait for `subscriber.activated`, which fires only after the first payment is confirmed on-chain.
</Warning>

  verifySignature(req); // see Webhook Integration for verification code

  const event = JSON.parse(req.body);

  if (event.event === 'subscriber.enrolled') {
    const { subscriberId, email, planId, gracePeriodEndsAt } = event;
