How to Send a Marketing Campaign Using WhatsApp API?

Sending a marketing campaign is the final and most important step when working with WhatsApp Business API. After uploading contacts and creating an approved template, the next task is to deliver that message to the right audience in a structured and controlled manner. In this article, we will understand how to create and send a marketing campaign using WhatsApp Business API through the Interakt platform.

This guide explains the entire campaign creation process step by step, starting from accessing the campaign section to making the campaign live.


Understanding the Campaign Flow in WhatsApp Business API

Before sending any campaign, three major steps must already be completed:

  1. Contacts must be uploaded into Interakt
  2. A marketing template must be created and approved
  3. The template must be ready to use inside a campaign

Once these steps are done, the third and final step is sending the campaign. This is the stage where your message actually reaches users on WhatsApp.


How to Send a Marketing Campaign Using WhatsApp Business API?

Step 1: Accessing the Campaign Section in Interakt

To begin, log in to your Interakt dashboard, which is connected to your WhatsApp Business API account.

On the left-hand side of the dashboard, move your cursor to the menu and click on the Market option.

Step 3: Opening the Campaign Area

Inside the Market section, you will find the Campaign option. Click on it to proceed.

Here, you will see an option to Create New Campaign. This is where the campaign creation process starts.

Step 4: Starting a New Campaign From Scratch

Once you click on Create New Campaign, select the option Start From Scratch. This means the campaign will be created entirely from the beginning without using any pre-built flow.

Naming the Campaign

Now, enter a campaign name.
For example, the campaign name can be Logo Promotion.

The campaign name is for internal reference and helps you identify campaigns later in reports and dashboards.


Step 5: Choosing the Audience

The first and most critical step in campaign creation is selecting the audience.

Selecting the Audience Type

Click on Choose Your Audience.

Since this campaign is being sent only once, select One Time.
The Ongoing option is not used here and will be explained in a separate session.

Understanding Why Filters Are Required

By default, all contacts may appear in the list. However, sending messages to everyone is usually not desired. WhatsApp Business API requires precise targeting.

At least one audience filter is mandatory.
If no filter is applied, Interakt will not allow the campaign to proceed.

Applying Audience Filters Using Tags

Click on Add Filter.

Choose Tags as the filtering method.
At the top, you will see existing tags that were created earlier.

Select the Students tag.

This tag was applied earlier when contacts were uploaded using an Excel file. Because of this, the campaign will be sent only to those contacts who have the Students tag applied to them.

Applying the Filters

Scroll down and click on Apply Filters.

Now, the selected audience is finalized.
The system will show how many contacts will receive the message.


Step 6: Creating the Message Using a Template

After selecting the audience, scroll down to the Create Your Message section.

Choosing an Approved Template

Under Choose Template, select the template that was created earlier.

In this case, select the Logo Promotion template.

Templates ensure that messages comply with WhatsApp policies and maintain a consistent structure.

Step 7: Defining Template Variables

Once the template is selected, scroll down to the variable section.

Assigning Variable Values

If the template contains variables, they must be defined again at the campaign level.

For Variable 1, select Name.

If the value is already selected by default, no changes are needed.
If not, manually select or type Name.

This ensures that each recipient sees their own name in the message.

Enabling Button Click Tracking

Enable Button Click Tracking.

This allows you to track:

  • Which users clicked the website button
  • Which users clicked the call button
  • Which users clicked the quick reply button

Tracking helps analyze campaign performance and user behavior.

Step 8: Scheduling the Campaign Message

Scroll down to the next step, which is Schedule Your Message.

Understanding Scheduling Options

You have multiple options here:

  • Immediate – Sends the message instantly
  • Custom Date and Time – Sends the message at a fixed future date and time

When to Use Scheduling

Scheduling is commonly used during festivals or special occasions. For example, festival wishes can be scheduled in advance so that messages are sent automatically on the correct date and time.

Sending the Campaign Immediately

In this case, select Immediate because the message needs to be sent right away.

Click on Done to move to the next step.

Step 9: Setting Retry for Failed Messages

Now you will see the option Set Up Retry for Failed Messages.

Understanding Message Delivery Failures

When sending messages to a large number of users, it is possible that some messages may fail due to technical reasons such as:

  • Network issues
  • Device restrictions
  • Temporary WhatsApp delivery issues

How Retry Works

If retries are enabled:

  • The system retries sending failed messages after exactly 24 hours
  • If delivery still fails, another retry happens after the next 24 hours

When to Enable or Disable Retry

Retries are useful for promotional campaigns where timing is flexible.

However, retries are generally not recommended for festival messages.
For example, if a Diwali message is delivered one day late, it loses its relevance.

In this campaign, retries are not enabled.

Click on Done to continue.

Step 10: Making the Campaign Live

This is the final step of the campaign creation process.

Setting the Campaign Live

You will now see the Set Live button.

Click on Set Live.

Sending the Campaign

Click on Send.

Since retries are not enabled, select Set Live Without Retries.

Click on Skip and Set Live.

Campaign Execution and Message Delivery

Once the campaign is set live:

  • The system starts sending messages to the selected audience
  • Messages are delivered using WhatsApp Business API
  • Users receive the message directly on WhatsApp

Within a short time, the message will appear on the recipient’s WhatsApp.


Understanding the Complete Campaign Workflow

The full campaign workflow includes:

  • Audience selection using tags
  • Template-based message creation
  • Variable personalization
  • Scheduling or instant delivery
  • Optional retry handling
  • Final campaign activation

Each step ensures better targeting, compliance, and delivery control.

By using tags and templates, businesses can send relevant messages to the right audience.
