Smart COD Control v1.3.1 supports Vonage (formerly Nexmo) as an SMS provider for OTP verification. Vonage offers competitive rates across South Asia, the Middle East, and Southeast Asia — regions where Cash on Delivery is most popular. This guide walks you through the full setup.

Vonage OTP verification for WooCommerce COD

What You Will Need

Step 1: Create a Vonage Account

  1. Go to vonage.com and click Sign Up Free.
  2. Verify your email. Vonage provides free trial credit so you can test SMS immediately.
  3. Once logged in, go to the Vonage API Dashboard.

Step 2: Get Your API Credentials

  1. On the dashboard, find the API key and API secret at the top.
  2. Copy both values — you will paste them into Smart COD Control.

Tip: Never share your API secret publicly. Treat it like a password.

Step 3: Set Your Sender Name

With Vonage you can use an alphanumeric sender ID (e.g., MyStore) in most countries. Go to Account → API settings in the Vonage dashboard to configure your default sender name. Note that some countries (like India) require a registered DLT sender ID — check Vonage documentation for your region.

Step 4: Configure Smart COD Control

  1. Go to WooCommerce → Smart COD Control → OTP Settings.
  2. Toggle Enable OTP Verification to ON.
  3. Under SMS Provider, select Vonage.
  4. Enter your API Key and API Secret.
  5. Set the From Name (your brand name or phone number).
  6. Click Save Settings.

Step 5: Customise the OTP Message

Use the {otp} placeholder in your message. Keep it under 160 characters. Example:

Your MyStore COD verification code is {otp}. Do not share this code.

Step 6: Test It

  1. Open an incognito window and go through checkout.
  2. Select Cash on Delivery.
  3. Enter your own phone number and click Send Code.
  4. You should receive an SMS from Vonage within seconds.
  5. Enter the code and complete the order.
