Payments and orders

Stripe, Iranian gateways, webhooks, subscriptions, risk, tax, shipping, and vendor payouts.

Skill	What it covers
payment-gateway-integration	Integrate a payment provider with idempotent charges, signature-checked webhooks, and an explicit map from provider states to order states. Use when adding or changing checkout payment, capture, refund, or payment notification handling.
order-and-webhook-reliability	Accept order and payment webhooks with a raw-body signature check, durable deduplication, and reconciliation against the source of truth. Use when handling order events, payment notifications, or outbound webhook delivery.
subscription-billing	Model subscription state, renewal charges, proration, and dunning without treating a renewal as a new one-time checkout. Use when adding or changing recurring billing, plan changes, cancellation, or failed renewal recovery.
fraud-and-risk-basics	Hold or review risky payments using provider signals, velocity, and 3-D Secure without storing card numbers. Use when adding payment risk checks, a manual review queue, or decline handling for card abuse.
tax-and-shipping	Calculate tax and shipping from the destination and the store's configured rules, and store the breakdown on the order. Use when changing tax classes, shipping zones, rates, or the amount shown before payment.
multi-vendor-payouts	Split a marketplace order by vendor, record commission as ledger entries, and pay vendors only settled amounts. Use when adding vendor catalogs, commissions, refunds that cross vendors, or payout batches.
stripe-payments	Take card and wallet payments with Stripe PaymentIntents or Checkout Sessions, idempotency keys, and signed webhooks that move the order to paid. Use when adding Stripe to a store, handling Stripe webhooks, or refunding through the Stripe API.
iranian-payment-gateways	Integrate Zarinpal and other Shaparak redirect gateways with a server-side verify call, Rial and Toman amounts, and one paid transition per authority. Use when adding an Iranian payment gateway or fixing callback, verify, or amount handling for IRR or IRT stores.
