How to Set Up
WhatsApp API Campaigns in Wavixo

Overview

WhatsApp allows businesses to send pre-approved template messages as automated notifications once their WhatsApp Business API goes live.
These notifications may include:
Account updates

Payment confirmations

Shipping or delivery updates

Webinar or event confirmations

With Wavixo, businesses get a simple and reliable way to:
Automate WhatsApp notifications using APIs

Track performance through campaigns

Send WhatsApp Broadcasts in addition to automation

In this guide, you’ll learn how to send automated WhatsApp messages using Wavixo in just three simple steps.

Pre-requisites

Before setting up a WhatsApp API campaign, make sure you have:

1. A verified WhatsApp Business API account

2. At least one pre-approved WhatsApp Template Message

3. A tool to make HTTP/HTTPS requests
(Postman is used as an example in this guide)

Step 1: Create an API Campaign in Wavixo

To create your first API campaign:
Log in to your Wavixo account

Create a new project or open an existing one

Navigate to Campaigns

Click Launch Campaign

Select API Campaign

Create your campaign and set it Live

🎉 That’s it — your first WhatsApp API campaign is now created.

Step 2: Copy Your API Key

Next, you’ll need the API key to authenticate API requests.
How to Copy the API Key
Open your Wavixo Project

Go to the Manage page

Copy the API Key

📌 Important Notes
The API key is a secret authentication key

Store it securely

You can regenerate the key anytime if required

This key will be used while sending automated WhatsApp notifications.

Step 3: Send a Notification to Users

Now, use the campaign name and API key from the previous steps to send messages.
The Wavixo API is designed to:
Accept dynamic parameter values

Automatically fill those values into the selected template

Send the message instantly to the user

This removes the need to manually configure messages on the business side.
You can refer to the Wavixo API Reference Documentation to understand all API fields in detail.

Sending Your First WhatsApp Notification

Once everything is configured:
1. Trigger the API request from your backend

2. The selected template message is sent automatically to the user

3. All dynamic values are populated via parameters

WhatsApp API Campaign vs WhatsApp Broadcast Campaign

It’s important to understand the difference between the two.

Triggered automatically by a user action or event

Messages are sent via APIs

Fully automated

Examples:
Abandoned cart notification for e-commerce stores

Payment confirmation after a successful transaction

WhatsApp Broadcast Campaign

Messages are sent manually

You can choose:
Pre-approved Template Messages

Regular Messages (within the 24-hour window)

You configure:
Dynamic values

Target audience

Campaign timing

Examples:
Event reminder sent to all participants

When to Use API Campaigns

API campaigns are ideal when:
1. Messages need to be sent automatically

2. Notifications are event-based

3. Real-time communication is required

This makes them perfect for transactional and system-driven notifications.
