WhatsApp routing is for the merchant number on the store. Customers still check out on the storefront; the shop gets a chat ping.
- In Portal, open the store messaging or WhatsApp settings.
- Enter the shop WhatsApp number in international format and save.
- Place a test order on the storefront (a low-value item is enough).
- Confirm the WhatsApp thread shows the order, items, and customer notes.
- Reply from WhatsApp as you normally would — status updates still happen in Portal or Cloud POS.
