Checkout Blocks lets Shopify Plus merchants add and manage content blocks in checkout without editing theme code. Merchants can use the app to show key messages, trust badges, guarantees, gift message fields, savings notices, and customer testimonials in the checkout experience. This helps keep important buyer information visible at the point of purchase while giving merchants a simple place to update checkout content.

• Add announcement, guarantee, and savings messages to checkout
• Show trust badges with icons, titles, and short descriptions
• Let customers add a gift message during checkout
• Display customer testimonials with ratings and verified labels
