Shopify Checkout Booster
Enhance and extend your Unzer payment integration with the Shopify Checkout Booster app
Shopify Checkout Booster is a Shopify application designed to enhance and extend Unzer payment integrations within your store. It enables you to display dynamic messaging widgets on product and cart pages, helping promote available Unzer payment methods and provide customers with clear, up-to-date information about their payment options.
Beyond storefront messaging, the app extends the capabilities of standard Unzer payment apps by monitoring external transaction updates and ensuring reliable two-way synchronization between your Shopify store and Unzer Insights. This helps maintain consistency and accuracy across both systems throughout the payment lifecycle.
Additionally, the app allows you to configure advanced rules for each active Unzer payment method. These include customizing display names and ordering at checkout, as well as defining availability conditions based on factors such as customer location, currency, and other contextual criteria.
