# Stripe Webhook Auth Policy

The Stripe Webhook policy secures your incoming webhooks by validating that the
request was sent by Stripe.

## Configuration

The configuration shows how to configure the policy in the 'policies.json' document.

```json title="config/policies.json"
{
  "name": "my-stripe-webhook-verification-inbound-policy",
  "policyType": "stripe-webhook-verification-inbound",
  "handler": {
    "export": "StripeWebhookVerificationInboundPolicy",
    "module": "$import(@zuplo/runtime)",
    "options": {
      "tolerance": 300
    }
  }
}
```
