Commerce plugins

Official store plugins for USDC on Base via the hosted Autlantic Billing API. They create single-use payment links, redirect buyers to hosted checkout, and mark orders paid from signed webhooks.

Platform	Status	Install	Source
WooCommerce	Available (1.1.3)	GitHub release zip	`integrations/woocommerce` · mirror woocommerce-autlantic
Magento 2	Available (1.1.0)	Packagist `autlantic/module-billing`	`integrations/magento` · mirror magento-autlantic
Shopify	Checkout blocked (external) on Payments Partner; custom wiring available	See Shopify below	`integrations/shopify` · mirror shopify-autlantic

Store currency must be USD or USDC. You need a merchant portal API key (abk_test_… / abk_live_…) and a webhook endpoint secret.

Shared checkout flow

Customer selects Autlantic at checkout (Woo / Magento), or follows a payment link (Shopify custom wiring)
Plugin/app creates POST /v1/payment-links (maxUses: 1)
Customer pays on hosted Autlantic checkout
payment.paid webhook (header x-autlantic-signature) marks the order paid

One-time payment-link refunds are manual (merchant sends USDC back). Invoice refunds via API apply only where an Autlantic invoice id exists (WooCommerce Subscriptions path).

WooCommerce

WordPress plugin zip with the PHP SDK vendored. Download 1.1.3 from GitHub releases and upload under Plugins → Add New.

WooCommerce → Settings → Payments → Autlantic Billing
Paste API key and webhook signing secret
Register in the Autlantic portal → Webhooks:
https://your-store.example/wp-json/autlantic/v1/webhook

Optional soft dependency: WooCommerce Subscriptions (week / month / year, interval 1). Full README: integrations/woocommerce.

Magento 2

Composer module autlantic/module-billing 1.1.0 (Magento module name Autlantic_Magento). Requires Magento Open Source / Adobe Commerce 2.4.6+ (or Mage-OS) and PHP 8.1+. Depends on autlantic/billing (resolved from Packagist automatically).

Production (Packagist)

bash

composer require autlantic/module-billing:^1.1
bin/magento module:enable Autlantic_Magento
bin/magento setup:upgrade
bin/magento cache:flush

Fallback (VCS mirror) if Packagist is unavailable:

bash

composer config repositories.autlantic-magento vcs https://github.com/Autlantic/magento-autlantic.git
composer require autlantic/module-billing:^1.1

Stores → Configuration → Sales → Payment Methods → Autlantic Billing
Enable, paste API key and webhook secret
Portal webhook URL:
https://your-store.example/autlantic/webhook

Full README: integrations/magento.

Shopify

Native checkout payment method

Offsite payments app (Hono) plus a payments extension. Listing Autlantic at Shopify Checkout requires an approved Shopify Payments Partner app. Ordinary Partner status is not enough. Until approval, merchants cannot enable Autlantic as a payment method on production checkouts. Status: blocked (external).

Source and deploy notes: integrations/shopify · mirror shopify-autlantic.

Custom wiring (SDK + payment links)

You can still accept Autlantic USDC for Shopify orders without the payments extension by using any server SDK (or the HTTP API) next to Shopify:

Create a single-use payment link for the order amount (USD/USDC) with your merchant API key
Send the customer to the returned hosted checkout URL (email, draft order note, custom button, wholesale portal, etc.)
Register a webhook endpoint and verify x-autlantic-signature
On payment.paid, mark the Shopify order paid / fulfill via the Shopify Admin API

This is not Autlantic inside Shopify Checkout’s payment selector. It is the same payment-link flow as a custom storefront. Suitable for invoices, wholesale, and “pay outside checkout” flows while Payments Partner is pending.

Minimal shape (Node example; same idea in PHP / Python / etc.):

import { AutlanticBilling } from "@autlantic/payments-recurring";

const billing = AutlanticBilling.fromEnv(); // AUTLANTIC_BILLING_API_KEY + API URL

const { paymentLink, url } = await billing.createPaymentLink({
  amountUsdc: 49,
  maxUses: 1,
  metadata: { shopifyOrderId: "1234567890" },
});
// redirect buyer to url (/checkout/link/:id)
// on payment.paid webhook → Admin API mark order paid using metadata.shopifyOrderId
