Follow these steps to connect your WhatsApp Business API and start sending messages through Otpiq.

​
Prerequisites

Before starting the integration, ensure you have:
  • A Facebook account with admin access to your Meta Business Account.
  • A phone number ready for verification.
The phone number cannot be currently registered on the regular WhatsApp or WhatsApp Business mobile apps. If it is, you must delete the account from the app first.

​
Step 1: Connect via Otpiq Dashboard

1

Navigate to WhatsApp Settings

Log in to app.otpiq.com and go to WhatsApp → Account.
2

Start Integration

Click “Connect WhatsApp Account” to launch the embedded signup process.
3

Complete Facebook Signup

Follow the prompts to sign in to Facebook, connect your Meta Business Account, and grant Otpiq the necessary permissions. Once finished, your account will be automatically linked.

​
Step 2: Create WhatsApp Templates

To send business-initiated messages, you need approved templates.
1

Go to Templates

Navigate to the Templates section in your Otpiq dashboard and click Create New Template.
2

Design Your Template

Select a category (Marketing, Utility, or Authentication), set the language, and fill in the content (header, body, buttons).
3

Submit for Approval

Submit the template to WhatsApp. Approval usually takes less than 24 hours.

​
Step 3: Send Messages

Once your templates are approved, you can send messages using the Otpiq dashboard or API.
Test easily: Go to Dashboard → Messaging → Send SMS to build and test your WhatsApp template messages without writing any code.
Here is an example of sending a template via the API: 
{
  "phoneNumber": "9647501580221",
  "smsType": "whatsapp-template",
  "provider": "whatsapp",
  "templateName": "auth_temp_new_no_exp",
  "whatsappAccountId": "68c46fecc504cdcec8fb3ef2",
  "whatsappPhoneId": "68c46ff3c504cdcec8fb3f5e",
  "templateParameters": {
    "body": {
      "1": "123456"
    }
  }
}
Check the API Reference for complete endpoint details.
