Watchdog checks your store every 5 minutes, and you can press Check now any time. It compares sales with a normal hour for your store, once it has about 4 weeks of history.
It also checks that Zyro still sees visits, and how fast pages load on real phones. It looks for $0 orders, leaked codes, and problems with checkout or add to cart. It checks stock, deliveries, customs, and the tools Zyro sends events to. Checkout, stock, delivery and customs checks are for Shopify stores.
Zyro flags a discount code when shoppers from coupon sites use it. It also flags a code used 3 times more than in a normal week.
When something breaks, it emails you. It can also post to Slack, Discord, Telegram, Microsoft Teams or Google Chat.
If a problem was expected, mark it "This is expected". Do that 3 times in 30 days for the same check and Zyro stops emailing you about it. Urgent problems always email.
