Developer guides
Classify a product, quote the duty and tax owed at its destination, and keep your live secret key on your server. The API reference carries the complete request and response contract for every call.
Integration path
sk_live_* in your server environment. Never expose it in browser
code, source control, logs, or recordings.
POST /v1/classifications to get the HS tariff code the quote
request needs.
POST /v1/tax_quotes with integer minor-unit
amounts and the destination country.
Walkthrough
Watch Claude Code read the live Scalar docs, use a disposable sandbox key in a real terminal, and complete one checkout-configuration request. The recorded key was revoked; no credential value is shown.
Classify a product and request a tax and duty quote with Scalar and curl, without creating a payment or moving any money.
Follow the public sample store from a test checkout through local setup with a Test secret key and publishable key.
The public production store runs the current 0.9.5 tax-quote contract with durable order persistence and signed-webhook reconciliation ready. Its daily transaction cap is 50.
Checkout admissions are enabled, and public Sandbox evidence shows succeeded Custom API transactions. Exact durable-order and signed-webhook reconciliation remains pending before the lifecycle is accepted.

Go from package setup through the quote-to-payment flow. The package's webhook handling remains unsupported, so merchants use polling fallback rather than treating any protected demo receiver as package callback support.
The capped public production-Sandbox store runs the current tax contract and has reconciled an accepted payment, cancellation, and signed callbacks. The separate keyless preview remains available for visual exploration only.

Walkthrough
The branded sample store, native product and cart, Blocks success, a completed 3DS challenge, and the classic-checkout decline-to-retry flow. The public store uses fictional products and Open Border sandbox payment rails. Its persisted commerce orders, Test payment intents, signed lifecycle deliveries, and Sandbox dashboard transactions reconcile without moving live money.
The current public download is immutable release 0.2.3. The store's current installed version must be proven from the host and is not inferred from the candidate artifact lock. This 23-second clip is transaction proof, not install or configuration setup proof. Only provider-approved Test payment data is used; no credentials, card data, customer data, or internal identifiers are shown.
The recording documents the maintained Luma product and cart flow. The current installable release and staging runtime are 0.1.12.
The retained exact-one Sandbox order, tax quote, payment intent, and terminal signed webhook reconciled on 0.1.7. Shipment fulfillment later succeeded on the production demo's immutable 0.1.8 runtime without another payment. Production deployment, provenance, and signed-out smoke passed. The public demo remains preview-only until the shared-Sandbox lifecycle and dispute UI evidence-field prefill are recorded.
Written setup guide · Open the public Magento product preview.
The maintained package commands, the immutable Composer artifact check, Magento services and installation, Admin payment configuration, and the running Luma storefront. The video verifies exact release 0.1.8; the written guide installs the current immutable 0.1.12 release.
Read the current 0.1.12 steps in writing. A fresh 0.1.12 setup walkthrough, or explicit product-owner acceptance of this historical preview, remains pending.
Written
Every walkthrough above has a written equivalent: the same setup, step by step, from prerequisites through a test payment to going live. Readable on a slow connection, with a screen reader, or alongside the video.
