OrderProof – OTP Order Verification for WooCommerce

Fake Cash on Delivery orders cost you shipping, return-to-origin (RTO) fees and stock that sits in a courier van. OrderProof adds COD verification to WooCommerce: every COD customer verifies their phone number before you ship. They receive a one-time code (OTP) on WhatsApp and type it to confirm the order.

No SMS gateway, no per-SMS bills: codes are sent from your own WhatsApp Business number through Meta’s official WhatsApp Cloud API. It works for customers in any country.

How WhatsApp OTP verification works

1. A customer places a Cash on Delivery order.
2. The order waits in “Awaiting WhatsApp verification”. It holds no stock and no “New order” email is sent yet.
3. The customer gets a 6-digit code on WhatsApp and types it on the verification page (with a copy-code button in WhatsApp).
4. The order becomes a real order: stock is reserved and your usual emails go out.
5. Orders that are never verified are cancelled automatically after a few hours.

Test mode lets you try the whole flow before you connect WhatsApp: the code is shown on the verification page instead of being sent.

External services

This plugin connects to the WhatsApp Business Platform (Cloud API), operated by Meta Platforms, Inc., to deliver one-time verification codes.

• When: only if you turn on WhatsApp OTP, turn Test mode off and enter your own Cloud API credentials; then each time a Cash on Delivery order needs verification or the customer asks for a new code.
• What is sent: the customer’s phone number, the one-time code, and the name and language of your message template, to https://graph.facebook.com/ with your access token.
• Terms: https://www.whatsapp.com/legal/business-terms
• Privacy policy: https://www.whatsapp.com/legal/privacy-policy

No other data leaves your site, and nothing is sent while WhatsApp OTP is off or in Test mode.
