Sofenx Confirm & Upsell

The app adds an OTP verification block to the Thank you page for cash-on-delivery orders. It uses the phone number already provided through Shopify checkout and sends a code through the merchant's own Twilio or Infobip account. The buyer confirms the code, and the app records the result, adds merchant-defined order tags, and can tag or cancel unverified orders after a chosen timeout. Merchants can also display a configurable product link after checkout.
