Razorpay webhooks

Recurring subscriptions are driven by Razorpay webhooks at POST /api/subscription/webhook.

  • The endpoint verifies the x-razorpay-signature against your RAZORPAY_WEBHOOK_SECRET using a constant-time comparison.
  • Deliveries are idempotent — a duplicate event id is ignored.
  • Handled events: subscription.charged (renew + record an invoice), subscription.activated, subscription.cancelled, subscription.halted, subscription.completed, and payment.failed.

Configure the webhook URL and secret in the Razorpay Dashboard. See Subscriptions & auto-pay.
