Afterpay On-Site Messaging is a free Shopify app from Afterpay, the buy-now-pay-later provider owned by Block. It adds \u201cpay in 4\u201d installment messaging to your product and cart pages, so shoppers see the Afterpay option before they reach checkout. On the Shopify App Store it holds a 3.0\/5 rating from 56 reviews, and in our live detection data it runs on 1.8% of Shopify stores, which makes it one of the more widely installed payment-related apps we track.<\/p>\n

The verdict upfront: this app only displays Afterpay messaging, it does not turn Afterpay on as a payment method. You have to enable Afterpay at your Shopify checkout first, and the app simply surfaces the installment option on your storefront. Used that way it is a small, free conversion nudge for stores that already offer Afterpay. Installed expecting it to add Afterpay payments, it does nothing, which is exactly what most of its one-star reviews describe.<\/p>\n

What Is the Afterpay On-Site Messaging App?<\/h2>\n

Afterpay On-Site Messaging is a widget app, not a payment gateway. Its single job is to place Afterpay\u2019s \u201c4 interest-free payments\u201d message where shoppers decide to buy: under the price on a product page, on the cart page, and as a footer badge. The app is built and supported by Afterpay itself, it launched in February 2021, and it is free to install.<\/p>\n

The distinction that trips people up is the setup order. Afterpay works as a payment option through your Shopify checkout, and this app assumes that is already in place. If Afterpay is not yet active at your checkout, the messaging has nothing to point at and will not display, no matter how the app is configured. That one requirement explains a large share of the negative reviews, where merchants installed the app expecting to add Afterpay and found it did nothing on its own.<\/p>\n
