WhatsApp Business API introduction: features, fees, and application methods

The WhatsApp Business API is a high-end service designed specifically for businesses, providing a set of programming interfaces (APIs) rather than a directly operable user interface. Unlike the free WhatsApp Business app, the WhatsApp Business API cannot be directly downloaded from app stores like the App Store or Google Play. Businesses must obtain these APIs through certified third-party service providers or engage technical personnel for custom development based on their needs.


To get a WhatsApp Business API number, businesses must undergo official WhatsApp review and authorization, then integrate the API into their own systems, such as Customer Relationship Management (CRM) systems, to automate messaging, receive messages, and manage customer conversations. Additionally, the WhatsApp Business API allows businesses to send a large volume of customized notifications, such as order status updates and travel reminders, while also providing real-time customer support.

Exclusive Features of the WhatsApp Business API

WhatsApp Broadcast Messages

The WhatsApp Business API supports broadcasting on a much larger scale than personal and regular business accounts, meeting the needs for mass messaging to numerous customers. Businesses can integrate the API with their own systems to automate the sending of bulk messages, such as notifications and reminders. However, WhatsApp has strict rules for these proactive customer messages, requiring official WhatsApp review before sending template messages.


For more advanced use, businesses can customize mass messages using preset customer names in the WhatsApp system. Personalized mass messages can improve open and response rates, as they don't feel like mass advertisements or notifications, making customers feel valued and thus enhancing loyalty.


Multi-Device Login

With the WhatsApp Business API, merchants can log in from multiple devices, which is a great convenience for customer service teams. Unlike the WhatsApp Business account, which only supports four devices, multi-device login allows multiple employees to handle conversations together, meeting the needs for collaborative work. In the face of numerous inquiries, conversations can be assigned or transferred to the appropriate staff for more effective handling.


Green Tick Verification

The green tick verification is unique to the WhatsApp Business API. This green checkmark is a symbol of WhatsApp's official brand verification and appears next to the contact name in the chat interface, enhancing brand credibility. Additionally, the WhatsApp Business API provides customizable business profile pages where companies can showcase their name, brand introduction, address, website link, and email address, among other things.

Setting Up Interactive Messages

Interactive messages come in two main forms: list messages and reply buttons.


List Messages: When customers respond with a number, the system automatically sends the preset information behind each number. Up to ten options are available for customers to choose from according to their needs.

Reply Buttons: After customers press a related button, the system sends the preset information. A maximum of three button options are provided, and each button's text is limited to 20 characters, so clarity is key.


Using interactive messages can shorten the time to understand customer needs and speed up the information retrieval process, automating the workflow.


Cloud Storage

In May 2022, Meta officially announced the launch of a new cloud system, "WhatsApp Cloud API," also known as "Cloud-based WhatsApp Business Accounts." Now, businesses have two different ways to use WhatsApp API features: the original method of purchasing API services from "WhatsApp Business Solution Providers" or the latest direct use of WhatsApp Cloud API.


Storing WhatsApp data in the enterprise's cloud ensures the security and privacy of conversation information, giving customers peace of mind.


WhatsApp Business API Charges

Utilities: Directly related to transactions, including post-purchase notifications and regular billing.
Marketing: Related to your business, products, or services.
Verification: Providing users with one-time passwords for authentication purposes.
Service: Initiated by the user; typically to resolve customer inquiries. Businesses can respond within a 24-hour customer service window.
