WhatsApp API: The Ultimate Guide to WhatsApp Business API 2025

Introducing WhatsApp Business API

WhatsApp API Explained

WhatsApp messaging app is available in two versions: WhatsApp Messenger and WhatsApp Business App.

WhatsApp Messenger is for personal communication. However, WhatsApp Business App is specifically for small businesses looking for a free yet effective communication platform to send one-to-one messages to their customers. It offers features like sending broadcast messages, quick replies, branding, etc.

However, due to the limitations of the WhatsApp Business App, the a need for a WhatsApp Business API that comprehensively addresses all these shortcomings. An API integration connects two or more platforms to implement a joint application or function. It allows various machines or sets of functions to work together to perform a set objective.

Also, it is not an application that can be downloaded like WhatsApp Business App, as it doesn’t offer a front-end UI. Instead, you will require a reputed and reliable third-party platform or Business service provider like Route Mobile.

WhatsApp Business App vs WhatsApp Business API

Both WhatsApp API and WhatsApp Business applications are designed for business communication and marketing.

However, they serve on different scales. Let’s evaluate both and how they are different from each other:

WhatsApp Business App

It is a free service ideal for small businesses, allowing customers to interact with customers instantly and easily.

This offers some basic automation features, such as the ability to organise chats, fast responses, and labels to organise chats for categorisation.

Here are some limitations of WhatsApp Business App:

• Send broadcast messages to only 256 users at one time
• No integration to WhatsApp chatbots
• No clickable buttons or quick replies offered
• Only the Recipients added to your contact list can receive your broadcast messages.
• No integration capability with a third-party application or platform

Types of WhatsApp Business API Messages

There are two types of WhatsApp Business API messages :

• Session Messages
• Templates Messages

Depending upon who is initiating the conversation and whether it is within the messaging window, companies can determine the type.

WhatsApp API Session Messages

Session messaging is a messaging limitation for API users imposed by WhatsApp. WhatsApp expects companies to reply to contacts’ incoming messages within 24 hours. Enterprises can only respond to their customers through session messages and are not allowed to message their contacts first.

WhatsApp Template Messages

Template messages are business-initiated conversations that follow WhatsApp guidelines, such as permission for opt-in and other security compliances.

These WhatsApp Business API messages feature pre-defined texts with pre-formatted content that can be utilised and customised multiple times to send messages.

Companies can also use message templates to respond to their contact’s last incoming message. Utilising message templates is not as simple as sending session messages.

The best an enterprise can do is connect with a BSP that can help with template approval, compliance, and regulations.

Here are some widely used WhatsApp message templates:

• Catalog Template: This is used to showcase the products or services in a visually appealing format, providing relevant information in detail, such as product name, features, pricing, description, and image.
  • Example: A luxury stationery brand shares its best-selling journals or diaries with high-quality product images and all other necessary information with its contacts. All they have to do is click on the CTA catalog button to reach the product page or, better yet, the checkout page.
• Coupon Code Template: As the name suggests, this template features coupon code details, making it easy and quick to apply. It attracts and retains customers and encourages them to make purchases.
  • Example: A flower gifting company sends exclusive coupon codes through WhatsApp coupon code template messages, allowing them to copy the code with one click and another CTA to redirect them to the shopping page where they can apply the copied coupon code.
• Multi-Product Message Template (MPM): This template allows businesses to highlight upto 30 items arranged into 10 different categories within just one message. This increases the chance of engagement and conversion as buyers get quick access to a whole catalog of products to explore.
  • An online grocery app, known to have hundreds of categories, can easily pick the top 30 items across 10 categories for listing featuring their best offers to attract customers to their app or website.
• Limited-Time Offer Template (LTO): Leverage customers’ sense of urgency by offering them time-sensitive offers or discounts. The template allows you to show the expiring date of the offer with active countdown timers to convey the urgency level and boost customer engagement dramatically.
  • Food ordering apps extensively use this feature on their selected menu items, especially around a festival or special event, aiming to boost sales quickly.
• Carousel Template: With the Carousel template, businesses can utilise multiple cards with horizontal swiping to easily communication, educate, or entertain their audience with storytelling. This establishes authority and boosts engagement.
  • An ed-tech company uses carousel template messages to educate students or learners about their courses or subject matter with CTA to buy them.
