Field reference

Field	Type	Notes
`id`	string ULID	Unique event id, prefixed `evt_`. Use for idempotent processing.
`type`	string	Always `payment.succeeded` for this event.
`created_at`	ISO 8601 timestamp	Server-side emission time.
`api_version`	string	Webhook API contract version.
`project_id`	string UUID	Project this event belongs to.
`data.subscription_id`	string UUID	Subscription identifier.
`data.plan_id`	string UUID	Plan the subscription is on.
`data.subscriber_id`	string UUID	Subscriber's project-scoped user id.
`data.provider`	string	Provider slug.
`data.external_payment_id`	string \| null	Provider charge / invoice / transaction id. `null` when the provider's success payload carried none.
`data.amount`	string	Charged amount in major units of `currency`, formatted as a string.
`data.currency`	string	ISO 4217 currency code.
`data.billing_reason`	string	Always present. Subscriby derives `subscription_create` (first successful payment) or `subscription_cycle` (renewal) from the subscription's payment history; for Stripe, the invoice's own `billing_reason` is passed through when present, so values such as `subscription_update` or `manual` can also appear.

Caveats

For first-time paid checkouts, subscription.activated is the matching subscription-level event — not subscription.created, which never fires for paid purchases.
Renewals pair payment.succeeded with subscription.renewed.
Card numbers, PAN, and CVV are never included in payloads.

subscription.activated (first payment), subscription.renewed (renewals) — paired subscription events.
payment.failed — alternative outcome.
