What is magento-checkout?

A guide to changing the Magento 2 checkout, the part of an online store where customers provide delivery details, choose shipping and payment, review totals, and place an order.

Use it to add payment methods, shipping carriers, totals calculations, and checkout interface changes.

It explains how Magento represents the cart and connects payment, shipping, totals, and checkout screens. This helps avoid breaking the order process when adding or changing checkout behavior.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.00878
Opus 5.5	$0.00015	$0.00351
Sonnet 5.5	$0.00008	$0.00176
Haiku 4.5	$0.00004	$0.00088

Security

Grade A, and why

magento-checkout scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Magento 2 Checkout Customization

Conceptual Architecture

Checkout Flow

Two-step checkout built with UI Components + KnockoutJS:

Shipping Step — address, shipping method selection
Payment & Review Step — payment method selection, order review, place order

Quote Model

The central data structure during checkout:

Magento\Quote\Model\Quote — the cart/checkout session
Contains items, addresses (billing + shipping), payment, totals
Converted to an Order on successful placement

Payment Methods

Three Categories

Type	Description
Gateway	Data passes through Magento to processor (Stripe, Braintree)
Offline	No external provider (Check/Money Order, Bank Transfer, COD)
Hosted	Redirects to external payment page (PayPal Redirect)

Implementation Components

Payment Model — uses Payment Gateway Command pattern with Magento\Payment\Model\Method\Adapter as a virtual type (recommended). Note: Magento\Payment\Model\Method\AbstractMethod is deprecated; avoid for new payment methods.
Config Provider — implements ConfigProviderInterface, returns JS config for checkout
JS Renderer — KnockoutJS component rendering the payment form in checkout
di.xml — register config provider into composite config provider
system.xml/config.xml — admin configuration fields for enabling/configuring the method

Payment Gateway Command Pattern

Modern approach (since 2.1) with configurable command chain:

Command objects for each operation (authorize, capture, refund, void)
Request builders construct gateway-specific payloads
Response handlers process gateway responses
Validators verify responses
Transfer factory creates HTTP transfer objects

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
