Introducing OTP Verification via WhatsApp for Cash on Delivery Orders

With the new WhatsApp OTP verification, merchants can ensure that every order is placed by a real, verified customer — improving confirmation rates and reducing fraud.

What’s New

Here are the key improvements included in this new integration:

• OTP Verification via WhatsApp

Customers will receive a one-time password directly through WhatsApp to confirm their intent to purchase.

• Pre-Purchase Verification

Merchants can request verification before checkout.

• Balance Management and Top-Up

Easily manage your OTP message balance and top it up through the Shopify Billing API, directly from the app dashboard.

• Language Customization

Send OTP messages in the language that best suits your customers.

• Mobile-Optimized Experience

The OTP entry form is fully responsive, easy to use, and styled to match your brand.

How to activate the feature in your store

Step 1: Make sure the Release Cash On Delivery app is active in your store.

Step 2: Next, go to the OTP Verification section within the app.

• Here you'll see the new WhatsApp Verification option.
• Activate it using the button on the right.

• Once activated, you'll be able to customize the style of the checkout modal to match your store's theme and colors.

Step 3: Configure your OTP verification via WhatsApp as you like

1. First, you'll see your account balance, where you can top up your balance at any time. We're also giving you $1.00 in free credits to try out the feature right now.

Note: It's important to keep in mind that if your balance runs out and you have no available credits, verification will automatically stop working.

2. If you'd like to receive a notification when your balance is low, you can add your phone number.
3. You can also activate the Persistent Verification option. With this feature, once a customer verifies their number, they won't need to do so again for 7 days. This improves the shopping experience for returning customers, and for security reasons, verification will be required after that period.

And that's it!

It's that easy to activate and use OTP verification via WhatsApp with Release Cash On Delivery. An update designed to give you more security, confidence, and better results for your COD orders.
