What is WhatsApp API – All Your Queries Answered

Since its launch in late 2009, WhatsApp has emerged as the world’s most powerful messaging app. Between 2009 and 2013, WhatsApp amassed 200 million monthly active users. By July 2021, this number crossed 2 billion+. Every day, over 100 billion messages are sent via WhatsApp. Further, users check the app 23 times a day, and 80% of WhatsApp messages are seen within 5 minutes.

WhatsApp is one of the most powerful communications tools available today. And yet, many brands refuse to see its potential for brand-customer communications!

Through WhatsApp, your brand can stay connected with customers via timely, meaningful, two-way conversations – no matter where they are. With the WhatsApp Business app, small and medium businesses (SMBs) can easily leverage the reach, ubiquity and immediacy of WhatsApp to share useful information with customers on-the-go. But if you are a mid-sized or large business (MLB) looking to cost-effectively and scalably boost sales and enhance global customer support, the WhatsApp Business API is perfect for you.

But what is WhatsApp API?

And how to integrate WhatsApp API with your communication stack?

This detailed guide will answer these two critical and common questions. And if you are an Indian company, keep reading to find answers to other queries like:

1. How is WhatsApp API different from the WhatsApp business app?
2. What are the benefits of WhatsApp API?
3. I want to know about the availability of WhatsApp API in India

5. Tell me about WhatsApp API pricing in India

But let’s start by addressing the first question: What is WhatsApp API?

What is WhatsApp Business API?

For businesses of every type and size, WhatsApp provides two solutions: a business app and an API. For SMBs, the app provides an easy, convenient, low-friction way to interact with customers on-the-go. This explains why in April 2021, the app was downloaded 16 million times worldwide, and why every day, about 175 million people message a business account via WhatsApp.

For MLBs looking to and engage in meaningful, contextual conversations with customers anywhere, at any time and on their preferred channel – the WhatsApp API is ideal. Launched in August 2018, the API is already popular with many MLBs, with top global companies like BMW, Uber, KLM Royal Dutch Airlines, and Netflix using it to communicate seamlessly with their huge global customer base.

These and many other large brands leverage WhatsApp’s reach and popularity to:

1. Share information and answer questions
2. Nurture leads
3. Send automatic updates and alerts
4. Provide support with chatbots
5. Re-engage existing customers with personalised offers and recommendations

The API makes it easy to connect with audiences, offer personalised experiences, increase sales, and even garner customer loyalty – cost-effectively and at scale. WhatsApp API is so versatile that you can even run ads and build shopping experiences directly into WhatsApp conversations.

However, the API cannot be directly downloaded. This is what differentiates it from the business app which can be directly downloaded from here. The API also doesn’t have a front-end interface. Rather, it must be integrated into your customer communications stack.

But how to integrate WhatsApp Business API?

This guide will address this question a little later. For now, what you need to know is that if you are a mid-size or large company looking to integrate WhatsApp into your business, the easiest way to do it is with a seamless, low-code platform like Gupshup. Once you do this, you can immediately start engaging with customers, addressing their questions and concerns, encourage conversions and repeat sales, and even send automatic updates, alerts and notifications.

Benefits of WhatsApp API for Mid-size/Large Businesses

1. Support for Multiple Use Cases

With a WhatsApp API, MLBs can talk to customers anywhere in the world on their preferred channel to:

1. Share important information, e.g. business address, description, website, email address
2. Send timely notifications and alerts
3. Drive incremental sales
4. Offer efficient, seamless customer support through conversations
5. Boost brand equity and recall value

2. Engage in Personalised, On-brand Conversations

WhatsApp is already immensely popular all over the world. By implementing the WhatsApp Business API in India or elsewhere, your MLB can easily access a readymade, powerful communication channel to engage in personalised interactions with any customer, anywhere in the world. Chat with them on their preferred channel, and personalise every conversation by leveraging key attributes like customer name, location, or contextual cues based on purchase or conversation history.

With the WhatsApp API, you can easily add a click-to-chat button to your business website or Facebook page, so customers can directly contact you via WhatsApp’s low-threshold, familiar interface.

3. Run Ads for Marketing and Promotions

Once you implement the API with an intuitive platform like Gupshup, you can easily run ads that click to WhatsApp from Facebook or Instagram to converse with potential customers, and gently guide them towards a sale. You can also re-engage existing customers with enticing personalised offers and tailored recommendations that they have opted-in to receive.

4. Send Timely Notifications and Updates

Did you know that many customers prefer to contact a company over WhatsApp, instead of through their website or social media page? They also prefer to be contacted by companies via WhatsApp, since it is both low-friction and low-disruption. With the WhatsApp API, you can easily send timely alerts, updates, reminders, confirmations, and recommendations. Send product shipping status, appointments reminders, booking or payment confirmations, verification codes, limited-time discount codes, special offers, and more. Utilise inbuilt template messages so you don’t have to design messages from scratch.

5. Build Shopping Experiences into WhatsApp to Drive Incremental Sales

The WhatsApp message API for India is a great way to drive incremental sales by building shopping experiences into WhatsApp conversations. Answer customer questions, provide product options and address pain points to smooth the buyer journey. By engaging on a channel that customers are already comfortable with, you can help them out, while also (gently) moving them towards conversion, checkout, sales, and even repeat sales.

How to Integrate WhatsApp API in Website?

Without a front-end interface, the WhatsApp API cannot be simply downloaded, much less used in a plug-and-play manner. Instead, end-users are required to take the API endpoint and integrate it into their business software.

So, how to integrate WhatsApp business API in the website? There are two ways.

#1: Apply Directly on Facebook

Get started by filling out the form on Facebook for Business here. Facebook will manually review your application. This process can take a few weeks to a few months. To prevent delays, make sure you provide all required information. Also, do:

1. Create a WhatsApp business account via Facebook Business Manager
2. Verify your business client account in Business Manager
3. Set up a line of credit for this account
4. Install the WhatsApp Business API client (a set of Docker containers, database and media volumes)
5. Set up a command-line tool (e.g. Terminal) or an app to perform cURL requests (e.g. Postman)

Once your business is verified, Facebook will review your compliance with the WhatsApp Terms of Service and WhatsApp Commerce Policy before granting you access to the API.

The WhatsApp API client runs on any Internet-connected machine that can run Docker for Linux, either in a virtual machine or on a Linux server. You can either choose the on-premises installation or use AWS or another standalone solution. After successfully installing the API client, your business can start integrating with the WhatsApp Business API like common REST APIs via HTTPS and receiving incoming messages using Webhooks.

Once the client is running, log in as “admin” to complete the setup and update your settings. Then register your business phone number by sending an API call to the account endpoint. You will need to send your WhatsApp business account a message from the test phone number to enable the Customer Service window to send any type of message within a 24-hour window.

If this method sounds too complicated, there is an easier and faster way: use an official WhatsApp Partner or Business Solution Provider (BSP).

#2: Use a WhatsApp Business API Provider in India (or your location)
