Making it official! SleekFlow is a WhatsApp Business Solution Provider.

Here’s the essential guide to the WhatsApp Business API you’ve all been waiting for! “What is an API?” you might ask. API stands for Application Programming Interface. It refers to a software intermediary that allows two applications to communicate with each other.

For example, you’re at a restaurant and you are deciding what to eat by looking at the menu. The kitchen at the back is in charge of preparing all food orders. The critical missing link here is the waiter – also known as the API –  who will communicate your order to the kitchen and deliver the food back to you.

Similarly, that’s what the WhatsApp Business API does! In order to use the WhatsApp Business 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, and interactive messages like WhatsApp buttons.

There are many other things you can do with the WhatsApp Business API, such as utilizing WhatsApp links that make it easier for customers to contact your business and also incorporating a WhatsApp Manager to better manage the surge in conversations!

What is WhatsApp Business API?

So, what exactly 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.

Great things come with a price, and indeed, WhatsApp Business API is a paid solution; however, the value is way over its worth. Other than the security and reliability it brings to both businesses and customers, WhatsApp Business API offers a wide range of additional features including quick replies, chatbots, multiple logins, mass broadcasting, personalized messages, 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 needs.

WhatsApp Business App vs WhatsApp Business API

*Third-party WhatsApp Business API providers are no longer available since June 2022 in accordance to Meta's policy change.

The differences, at one glance, can be summarized as shown in the table above. To understand each of the distinct features in-depth, read on.

7 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 7 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 an Official WhatsApp Business account, showing the business name instead of the business phone number, displayed even if the customer has not saved the business’s phone number yet.

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 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 template messages

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

WhatsApp Template Messages are pre-approved message templates for outbound notifications like delivery alerts and appointment reminders.

Template Messages cannot be used for marketing. You must use a WhatsApp Template Message if more than 24 hours have elapsed since the user’s last response to you. Any other types of messages sent outside the 24-hour window will fail to reach the user.

Creating template messages

When using official WhatsApp Business API providers such as 360dialog or Twilio, each template will need to be approved before it can be sent out. The approval process usually takes around 1 to 2 days for each template.

When creating a message template, you must add the following:

  • Name: A message template name can only contain lowercase alphanumeric characters and underscores. No other characters or spaces are allowed.

  • Type: Select the appropriate template type from the drop-down list. The template type must fall under one of the template type options, e.g. appointment update, issue resolution, payment update, etc.

  • Translations: All message template translations must be provided by you in the format below. The element name will be the same for all translations. When sending a message template from the WhatsApp Business API, you will specify the language you would like the message template to be displayed in by using the language field.

  • Variables: The correct format for variables is this string: {{#}}, where # represents the variable index. Note: variables must begin at {{1}}.

Formatting template messages

WhatsApp allows for basic formatting in message templates. Here are the formatting rules:

FormattingDescriptionSymbol Example
Italic textItalicize your message with an underscore on both sides of the text_text_Welcome to _SleekFlow_
Bold textPlace an asterisk on both sides of the text*text*Your total is USD *19.90*
Struck through textTo strikethrough your message, place a tilde on both sides of the text~text~This is ~better~ best!
Monospace text / codePlace three backticks on both sides of the text“`text“`Welcome to “`SleekFlow“`

Template message variables

When submitting a text-based template message for approval, you can add unique variables to personalize messages to your customers. Do note that each template message needs to contain at least one variable.

The variables are represented by numbered placeholders such as ‘{{x}}’. Each variable can be replaced with text that contains letters, digits, special characters, or spaces. 

However, variables cannot contain the following:

  • New lines

  • Tabulators

  • More than four consecutive spaces

For example, if you want your customer to receive this message:

Templatetext.png?w=791&ssl=1

You would need to submit the following template:

templateexample.png?w=791&ssl=1

Do note that WhatsApp will not approve templates with floating variables. Floating variables are lines with just variables and do not contain texts. Please surround the variables with information so it is clear what kind of data is inserted. 

WhatsApp session messages

As mentioned above, there are two types of WhatsApp Business Messages: Template Messages and Session Messages. 

WhatsApp Session Messages are any messages sent and received in response to a user-initiated message. A messaging session starts when a user sends you a message and lasts for 24 hours from the most recently received message. After that 24-hour window, the messaging session ends. You can then wait for users to message you, or instead, send a Template Message to invite the user to respond. 

WhatsApp Business API Conversation-based Pricing 2022

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 if the message is business-initiated or user-initiated.

Firstly, the starting 1000 conversations are free of charge!

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

MarketBusiness-initiated rate (USD)User-initiated rate (USD)

Interactive messages

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

Remember how back in the 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

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

Reply 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 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.
