Checkout Canary tests your checkout around the clock. It builds test carts for the places you ship to, confirms shipping options appear, and checks that your discount codes still apply. It's ready for shipping settings moving into Markets: it flags markets with shipping turned off or no active rates, and carrier services that aren't connected. You get one clear email when something breaks and one when it's fixed. No orders are placed and no customer data is read.

• Test carts confirm shipping options appear for every address you sell to
• Discount code checks catch expired, deleted or used-up codes
• Markets ready: flags markets with shipping off or no active rates
• Finds carrier services that aren't connected to any zone or market
• One alert when a problem starts, one when it's fixed. Never hourly spam
