With WhatsApp API you can send unlimited messages to saved and unsaved contacts and track real-time analytics of those sent messages to streamline your WhatsApp marketing strategy, leverage WhatsApp chatbot to automate your customer support, use team inbox to answer 1000s of customer queries at once, do product marketing, send business reminders, drive lead generation and do a lot more. The possibilities are endless.

So, in this article, we’ll walk you through the process of using DoubleTick WhatsApp API to send messages and offer some insights into real-world use cases.

Let’s dive in.

What is WhatsApp API?

The WhatsApp Business API is an application program interface that enables businesses to efficiently send and receive bulk WhatsApp messages in real-time. It helps businesses enhance their communication with customers by offering features like bulk WhatsApp messaging, interactive automated messages, quick replies, WhatsApp chatbots and a lot more. 

WhatsApp API allows businesses to send and receive unlimited messages, track message delivery, integrate a WhatsApp chatbot, and manage customer interactions all in one place. It also enables businesses to set up a product/service catalog for customers to browse and make purchases directly within WhatsApp. 

The WhatsApp Business API can be integrated with any third-party tools like Google Sheets, Shopify, Zoho, Zapier, WooCommerce and so on.

Step 2: Create a Channel

To proceed, click on “New List” >> Type list name >> click on “CREATE LIST”.

Step 3: Create a Contact List

Now add contacts to the broadcast list created.  You can do it manually or import bulk contacts from the Excel sheet.

Then, choose the approved message template you want to use.

When you’re done, you have two options:

​How to Send Messages to Individual Customers via DoubleTick

Step 1: Open DoubleTick

First, launch DoubleTick by clicking this link:

Once it loads, click the “Home” tab.

Step 2: Start or Find a Chat

If you’re messaging a customer who has already interacted with your business through WhatsApp, you can simply open the chat from the list or search for the customer’s name from the search box. 

If you want to start a new conversation, click on the “New Chat” button in the bottom-left corner and enter the customer's phone number. Then click “Start Chat” to open up the chat window.

Step 3: Choose a Template or Draft Your Message

WhatsApp prevents businesses from reaching out to customers with non-approved messages unless the customer initiates the conversation first. 

So, for the first message, you’ll have to choose an approved template by clicking “Send template”. You can personalize these templates by editing the dynamic fields.

Once a customer responds, asks a question, or initiates the conversation, you can reply freely and use all messaging formats available on WhatsApp, including:

  • Photos and videos

  • Audio

  • Documents

  • Products

  • Catalogue

…and more.

How Can Sending Messages via the WhatsApp API Benefit You?

Here are a few of the key benefits to send messages to your customer via WhatsApp API:

Bulk Messaging

WhatsApp and WhatsApp Business both limit the number of messages one can send, but with the WhatsApp API, you can send WhatsApp messages to unlimited saved and unsaved contacts.

Real-Time In-Depth Analytics

With WhatsApp Business API, you can track your broadcast campaign metrics like read, delivered, failed, unread and more in real-time.

Chat Automation

Automation means more time for the important stuff!

The WhatsApp API takes the hassle out of customer outreach, allowing businesses to connect with their audience faster and easier. Automated responses to FAQs and common inquiries give customers the answers they need without having to wait while giving you more time to focus on other projects.

For example, DoubleTick's Bot Studio lets businesses create complex bots using an intuitive visual builder. You can even link other tools and services like Shopify and WooCommerce to act as triggers in your automated customer journeys.

Team Inbox

WhatsApp and WhatsApp Business are not designed for large teams. They don’t offer access controls, user management, or analytics. For example, DoubleTick makes team management simpler by offering an intuitive team inbox for all WhatsApp conversations. There, admins can create team hierarchies, assign conversations to the right agents and track performance.

WhatsApp API Message Limitations & Rules

In order to leverage the potential of bulk messaging on WhatsApp API one must be aware of the limitations associated with it, as these are outside our (and any other provider's) control.

  • Message Templates: For business-initiated conversations, you can send only approved message templates. These templates need to be reviewed and approved by WhatsApp before they can be used. This process usually takes around 24 hours.

  • Message Sending Limits: Businesses have to stick within certain message limits as per their messaging tier.  There are 4 messaging tiers:

    • Tier 1: You can send messages to 1K unique numbers in a rolling 24-hour period

    • Tier 2: You can send messages to 10K unique numbers in a rolling 24-hour period

    • Tier 3: You can send messages to 100K unique numbers in a rolling 24-hour period

    • Tier 4: You can send messages to unlimited unique numbers in a rolling 24-hour period, but your sending volume is limited by the SLAs (service-level agreements) and the speed at which messages can be sent out.

  • Message Costs: WhatsApp charges an additional fee for each message sent through the API, with costs varying by country. This is on top of any platform fees charged by your chosen WhatsApp Business API provider.

How to Access the WhatsApp API

To get WhatsApp API, you can:

1. Get It Directly Through Meta

2. Get It via a Solution Provider

Let's explore the pros and cons of each of them in detail.

Access It Through Meta

Businesses have the option to access the WhatsApp Business API directly via Meta, but this means opting for a more DIY approach to WhatsApp API integration.

Here are the pros and cons:


  • Flexibility: With direct access to the WhatsApp API through Meta, businesses can create custom integrations and have more control over their messaging flow.

  • Cost-effective: Businesses only pay for what they use with this option, making it a more budget-friendly choice for companies.

  • Self-service: Businesses can manage their WhatsApp Business API account and integrations on their own, without relying on a third-party provider.


  • Highly technical: This option requires businesses to have technical expertise and knowledge to set up the integration and troubleshoot any issues.

  • Time-consuming: Direct access to the WhatsApp API through Meta means that businesses will need time and resources to set up and maintain the platform.

  • Limited support: While businesses have more control over this option, there is limited support available from Meta in case any issues arise.

  • No Support for Indian Credit Cards: Businesses need to add their own credit card to avail the WhatsApp API services directly from Meta. However, Meta does not currently support Indian credit cards for payment, making it inaccessible to many businesses in India.

Access It Through a Solution Provider

You can also access the WhatsApp API through a solution provider like DoubleTick for a completely managed integration. This means that DoubleTick takes care of the technical aspects, and you get a fully functional WhatsApp API solution right out of the box.


  • Easy setup: With DoubleTick, you can have a fully functional WhatsApp API solution in a matter of minutes—no technical expertise is required.

  • Payment Flexibility: DoubleTick can manage billing with Meta on your behalf. We can pay your bills to Meta and you can pay us via a wide range of payment gateways such as Razorpay, Stripe, Worldpay, and more.

  • Advanced features: DoubleTick offers all kinds of features that you’d need to build yourself in a DIY integration—things like team inbox, analytics, WhatsApp Chatbots, Order Booking bot and more.
