WhatsApp Business API: A definitive guide for your business (2024)

WhatsApp Business API: overview, functions, and pricing

Here’s the essential guide to the WhatsApp Business API you’ve all been waiting for! “What is an API?” you might ask. APIs, short for Application Programming Interfaces, function as software intermediaries that facilitate seamless communication between two applications, much like a skilled waiter in a restaurant.

In order to use the WhatsApp API, businesses will need to choose a provider and integrate it with software to fully unlock its function. With this powerful tool, your business can then streamline communication using functions like automated replies, WhatsApp broadcasting, chatbots, interactive messages like WhatsApp buttons, and more...!

What is WhatsApp Business API?

WhatsApp Business API is a tool specially designed for businesses to power communication with customers all across the globe safely and effectively.

In overly simplified terms, WhatsApp Business API can be explained as an upgraded version of the WhatsApp Business App. While the WhatsApp Business App supports small businesses with basic functions such as business profiles, auto-replies, labels, and more, the options are rather limited, especially for those dealing with a greater number of clients and daily inquiries.

WhatsApp API, other than the security and reliability it brings to both businesses and customers, offers a wide range of additional features, including quick replies, chatbots, multiple logins, mass broadcasting, personalized messages, WhatsApp API integration, and many more to help businesses sell better online.

How is WhatsApp Business API different from WhatsApp Business App?

Considering the differences between WhatsApp Business API and WhatsApp Business App is crucial. If a budget is required for this messaging solution, it will only make sense for business owners, marketers, customer support, or sales to truly weigh the pros and cons of each option, ensuring that the decision caters to the business's needs.

10 Advantages of WhatsApp Business API

What can you do with the WhatsApp Business API?

The possibilities are endless! Businesses can integrate the WhatsApp Business API with platforms like SleekFlow to access more functions and increase workflow efficiency.

As we work through these 10 advantages of WhatsApp Business API, the benefits of WhatsApp Business API will be as clear as day.

Verified WhatsApp Business accounts

When using the WhatsApp Business App to contact customers, only the phone number will be displayed.

In contrast, WhatsApp Business API allows businesses to have a WhatsApp Official Business Account (OBA), showing the business name instead of the business phone number, even if the customer has not saved the business’s phone number.

Official WhatsApp Business API

On top of that, there will also be a tiny green verification tick next to your business name to show authenticity and reliability.

not using the official WhatsApp Business API

With the WhatsApp Business green tick verification applied, you can avoid your WhatsApp Business account from being banned, saving the time and effort to go through all the hassle and suffering the consequences of never being able to use that number on WhatsApp again.

WhatsApp Business Template Messages

There are two types of WhatsApp Business Messages: Template Messages and Session Messages

WhatsApp Template Messages are pre-approved message templates for marketing, one-time password notifications, or outbound messages like delivery alerts and appointment reminders. WhatsApp Template Messages are categorized into:

  • Utility conversations

  • Authentication conversations

  • Marketing conversations

Here's how to determine your message category when you're putting Template Messages for WhatsApp's approval:

TypeUsageCategory of business-initiated conversation
MarketingPromotional offers, product announcements, discount codes, and moreMarketing conversations
One-time passwordsCodes for users to secure their accountsAuthentication conversations
Transactional messagesAccount or order updates, order delivery alerts, meeting reminders etc.Utility conversations

With a template message set up, you can personalize your messages by adding variables such as first name, birthday, and membership points, etc. to send out personalized WhatsApp broadcasts.

WhatsApp Business API conversation-based pricing

From February 2022 onwards, WhatsApp officially introduced a conversation-based model for the official WhatsApp Business API. No matter if it's Template Messages or Session Messages, they are all charged according to the number of conversations, depending on whether the message is business-initiated or user-initiated.

Firstly, the starting 1000 user-initiated conversations are free of charge!

Note: user-initiated conversations are also identified as service conversations. Charges for this type of conversation will not apply if your business does not reply to the users.

The pricing for each type of conversation will also follow the country that your business is in:

MarketBusiness-initiated rate for utility conversations (USD)Business-initiated rate for authentication conversations (USD)Business-initiated rate for marketing conversations (USD)User-initiated rate for service conversations (USD)
Hong Kong$ 0.0472$0.0425$ 0.0732$ 0.0224

WhatsApp Interactive messages

WhatsApp interactive messages encourage customer engagement by providing users with simpler options to communicate the products or services they need from your business.

Remember how back in our school days when we used to prefer multiple-choice questions over long-answer questions for exams? The same goes for this!

This fully explains why interactive messages tend to have significantly higher response rates and conversions compared to informational, text-based messages.

WhatsApp Business API interactive messages

WhatsApp List Messages

WhatsApp enables businesses to engage customers using list messages with up to 10 options, making the message flow simple, consistent, and efficient.

WhatsApp list messages

WhatsApp chat buttons

Up to 3 options can be provided for the users. This means that business users can design 3 buttons for the customers to select. It can even be combined with list messages when customizing an interactive message flow!

An important note when using interactive messages is that they can only be sent within 24 hours after the user-initiated message is sent. Also, the customers will not be able to select more than one option at a time, but they will be able to return to previous text messages.

It all depends on how you set up the buttons to make it fun for your customers!

WhatsApp Broadcast

With the WhatsApp broadcasting function, businesses can send out mass, but personalized messages to their customers to offer details about events or promotions.

Undoubtedly, this saves businesses a lot of time as marketers will no longer have to copy and paste each text individually while ensuring the customer’s name is spelled correctly!

For example, logistic firms can use this function to notify their customers of deliveries, educational firms can also use this to send out seat confirmations for seminars, and supermarkets can use this to send out flash promotions.

SleekFlow has opened up a new channel for us to conduct marketing and broadcasting effectively.

Hence, this not only allows more customer service agents to serve more customers at a time but also allows cross-functional team collaboration.

WhatsApp chatbots

Who should consider using WhatsApp Business API?

The useful functions of the WhatsApp Business API are extremely attractive, but it is still vital for business owners to consider the suitability of its usage based on their working industry.

1. Retail

The sale of goods and services directly to consumers makes the retail industry a rather fast-moving sector in the world of businesses. As digital technology drives customers towards online shopping and inquiries, O2O retail techniques are no longer an unfamiliar option to most retailers.

For retail businesses, a large number of daily incoming messages from customers can be quite overwhelming and time-consuming to manage. This makes WhatsApp Business API the most appropriate solution as it allows for automation, chatbot, and broadcasting, while at the same time making the account appear more trustable and reliable.

Retail selling is all about communication. The messaging data generated by SleekFlow is critical for us to drive lasting sales performance.

Also, WhatsApp Business API will be able to ease the procedures of scheduling and making appointments as they progress, thus improving customer satisfaction.

How to create a WhatsApp Business API account?

Firstly, businesses will need to choose a WhatsApp Business Solution Provider (BSP). These providers will process the business’ WhatsApp Business accounts and Template Messages by sending relevant information to WhatsApp.

To get the most out of WhatsApp Business API/WhatsApp Business Platform, Meta strongly encourages businesses to choose an official WhatsApp BSP or WhatsApp Business Solution Partner. Understandably, with so many BSPs for WhatsApp on the market, it might get a little overwhelming.

Here's why you should choose SleekFlow as the WhatsApp BSP:

  • Best pricing for businesses with a large volume of messages

Other than the conversation fees charged by Meta, businesses will be required to pay a subscription fee or provider fee to the WhatsApp BSP. SleekFlow offers a reasonable price according to your needs.
