API ReferenceBilling & Webhooks

Stripe webhook receiver (auth-exempt; the signature IS the auth).

POST
/v1/billing/webhook/stripe
curl --request POST \
  --url https://data.predictefy.com/v1/billing/webhook/stripe \
  --header 'Content-Type: application/json' \
  --header 'stripe-signature: example' \
  --data '{}'

Verifies the stripe-signature header against the RAW request bytes.

Credit grants. A signed, PAID (payment_status=paid, mode=payment) checkout.session.completed credits the SERVER-RECORDED checkout session EXACTLY ONCE — the grant amount and account come from the checkout_sessions row written at session creation, never from Stripe-supplied metadata. Idempotent through the stripe_events primary key and the session's consumed_at flag; replays and unknown, consumed or unpaid sessions answer 200 without crediting.

Wave C subscription lifecycle.

  • A subscription-mode checkout.session.completed consumes and binds the server-side subscribe intent.
  • customer.subscription.created mirrors into the subscriptions table ONLY when it traces back to such an intent. Metadata alone never mints a mirror, and a duplicate open subscription for an account is acknowledged without a mirror and flagged for manual cancel and refund.
  • updated and deleted events only ever UPDATE an existing mirror, never create one.

invoice.paid grants the plan's monthly credits from OUR plans row ONLY for billing_reason subscription_create or subscription_cycle — prorations and manual invoices never grant. At most once per billing period (period_start-keyed), never for a canceled mirror, idempotent through the stripe_events primary key. An ANNUAL subscription is granted twelve months at once, and only when the mirror (resolved from the Stripe price id) and the invoice's own line price both say annual AND the invoice's amount_paid is above zero; otherwise one month is granted. When the event's embedded line list is truncated (lines.has_more) the remaining lines are read from Stripe first; if they cannot be, the webhook answers 503 and records nothing, so Stripe retries. A switch between monthly and annual billing never grants or claws back by itself, and an upgrade grants its delta only when the funded period and the subscription bill on the same interval (for annual: the monthly difference x the whole months remaining in the prepaid year). An invoice.paid for a not-yet-mirrored subscription answers 503 so Stripe retries until the lifecycle event lands, bounded by Stripe's ~72h retry window.

All grants stay DARK until ops seed plans rows. Other event types are recorded and acknowledged. Processing errors answer 500 so Stripe retries.
