How do I integrate Afterpay with my Magento 2 store?

Afterpay ships an official Magento 2 module via the Magento Marketplace and via Composer (`afterpay/module-afterpay`). Setup is three steps: (1) create an Afterpay merchant account at portal.afterpay.com and grab your Merchant ID + secret key, (2) install the module + configure under Stores → Config → Sales → Payment Methods → Afterpay, (3) test in sandbox before flipping production. The module supports product page messaging (the “4 instalments of A$X” widget), cart messaging, and checkout. Afterpay was founded in Sydney in 2014 — it’s the de-facto BNPL rail for AU consumers, particularly fashion / DTC / lifestyle. We’ve integrated it on 30+ AU stores.
