While OTP Edge provides shared sender numbers for testing and quick starts, scaling your application requires you to bring your own WhatsApp Business Account (WABA). By connecting your own WABA, you gain:
  1. Your Brand Name and Logo as the sender.
  2. The Green Verification Badge (if approved by Meta).
  3. Direct Meta Billing (no markup on Meta’s conversation charges).

​
Prerequisites

Before starting this tutorial, ensure you have:
  1. A Meta Business Manager account.
  2. A Meta Developer account.
  3. Access to the OTP Edge Dashboard.

​
Step 1: Create a Meta App

  1. Go to the Meta for Developers portal and click My Apps.
  2. Click Create App.
  3. Select Other > Next > Business > Next.
  4. Name your app (e.g., MyCompany WhatsApp) and connect it to your Business Portfolio.
  5. Once created, scroll down and add the WhatsApp product to your app.

​
Step 2: Configure WhatsApp API

Inside your Meta App dashboard, navigate to WhatsApp > API Setup. You will see a temporary access token and a Phone Number ID. While this works for testing, you need to generate a System User Permanent Token for production.

​
Generate a Permanent Token

  1. Go to your Business Settings > Users > System Users.
  2. Add a new System User with an Employee role.
  3. Click Add Assets and assign your new App with Full Control.
  4. Click Generate New Token, select your app, and check the whatsapp_business_messaging and whatsapp_business_management permissions.
  5. Copy this Token immediately.
Now, head back to your OTP Edge Dashboard.
  1. Go to the Integrations tab.
  2. Click Connect Custom WABA.
  3. You will be prompted for three values:
    • Phone Number ID: Found in your Meta App > WhatsApp > API Setup.
    • WhatsApp Business Account ID (WABA ID): Found right below the Phone Number ID.
    • Permanent Token: The token you generated in Step 2.
Click Save & Verify. OTP Edge will instantly ping Meta to verify your credentials.

​
Step 4: Configure the Webhook

To ensure OTP Edge can track message delivery statuses (Sent, Delivered, Read, Failed), you must point Meta’s webhook to our servers.
  1. In the OTP Edge Dashboard (under Integrations), copy your unique Webhook URL and Verify Token.
  2. Go back to your Meta App > WhatsApp > Configuration.
  3. Click Edit under the Webhook section.
  4. Paste the URL and Verify Token from OTP Edge and click Verify and Save.
  5. Finally, click Manage on the Webhook fields and subscribe to the messages field.
Congratulations! Your WABA is completely integrated. All API requests made from OTP Edge will now automatically route through your official brand number!
