How does the checkout widget work?
After a successful checkout, the widget shows on the thank-you page with a "Join our WhatsApp community" prompt and a phone-number field. The buyer enters their number and confirms with Save Number; it's captured in Keaz and linked to their customer profile. The widget is shown only to buyers with no phone number in their order data, which prevents duplicates.
When exactly is it shown?
It's checked after every completed purchase and appears only when both are true: the purchase is complete and no phone number exists in the order data. Once a number is entered, the contact is created in Keaz and can be used immediately in flows, segments and newsletters.
What does Safe mode do?
Safe mode is a toggle, off by default. When on, the widget shows only under stricter conditions — e.g. clear opt-in intent — protecting you from non-compliant or unwanted capture. For privacy-sensitive markets or a strict GDPR reading, turn Safe mode on so you only collect numbers with clear consent.
