Revolutionizing Business Communications with WhatsApp Business API

In today’s fast-paced world, companies are constantly looking for more efficient ways to communicate with their customers. And here is where messengers come into play. WhatsApp, for example, is a potent tool for businesses that has surpassed two billion monthly active users.

There are two solutions for businesses of different sizes — WhatsApp Business App and WhatsApp Business API. This post will dwell on the latter, providing a complete overview of the tool and the best practices for sending WhatsApp API messages.

What is WhatsApp Business API?

WhatsApp Business API is a programmable interface that allows businesses to communicate with their customers on the WhatsApp platform in a more efficient and automated manner. With its help, you can send and receive messages, automate responses, create chatbots, and provide customer support on a larger scale. Ultimately, businesses can ensure a convenient communication channel and higher customer satisfaction.

How is WhatsApp Business API different from WhatsApp Business App?

WhatsApp API and WhatsApp Business App are two products designed for different business needs. While the WhatsApp Business App caters to small businesses, WhatsApp API is specifically built for businesses that require scalability. Unlike the WhatsApp Business App, WhatsApp API is suitable for bulk messages and provides such features as automated message triggers through integrations and APIs, multiple logins, and a support dashboard.

Moreover, WhatsApp for Business API comes with advanced chat automation capabilities and does not have an app or front-end interface. Instead, it needs to be integrated directly into business software. It’s noteworthy that WhatsApp API can only be accessed through WhatsApp Business Solution Providers (BSP).

Top features of WhatsApp Business API

WhatsApp for Business API offers a wide range of features to enhance customer engagement on the platform. With integrations to tools like CRM, analytics, and third-party apps, businesses can streamline their workflows and automate their communication. Additionally, WhatsApp API offers a Green Tick, indicating that the WhatsApp Business profile is verified, immediately looking more trustworthy.

Businesses can send bulk messages to stay in touch with their clients. This feature can be useful for marketing campaigns, promotional offers, or transactional notifications to a large number of customers.

In addition, with WhatsApp Business API, you can use message templates. They are pre-approved messages that businesses can use to send specific types of messages, such as appointment reminders, order confirmations, and shipping updates. These templates can be customized with dynamic variables like customer name, order ID, and date and time.

The platform also supports WhatsApp chatbots and interactive messages, providing businesses with innovative ways to engage with customers. Furthermore, companies can grant multi-agent access for customer support, enabling multiple team members to respond to customer inquiries simultaneously. Overall, WhatsApp Business API is a powerful tool for businesses that want to establish an effective and scalable communication channel with their customers on the WhatsApp platform.

Getting started with WhatsApp Business API

WhatsApp API is not available for direct access, so businesses must rely on external services. This approach helps to combat spammers, which is easier to achieve by controlling the companies with API access. Setting up WhatsApp Business API involves a few important steps:

  1. Choose a BSP. WhatsApp has a list of authorized services that provide businesses with the necessary infrastructure, tools, and support to use the WhatsApp Business API. You can choose a BSP depending on your needs and budget.
  2. Register your phone number. The phone number you want to use for your business must be registered with WhatsApp.
  3. Set up a Facebook Business Manager account. It is a key step to gain access to WhatsApp Business API since the Facebook Business Manager account allows you to manage all your Facebook assets, including WhatsApp.
  4. Verify your Facebook Business Manager account. Verification involves providing Facebook with documentation that proves your company’s identity and location.
  5. Set up your WhatsApp Business API account. Once you have completed the above steps, contact your BSP to configure your settings, such as message templates.
  6. Get your message templates approved. Before you can use template messages, they must be approved by WhatsApp. You’ll need to submit your templates to WhatsApp for review.

After your account is set up and your templates are approved, you can start using the WhatsApp Business API. It is important to note that the above steps may vary depending on your BSP and the specific requirements of your business.

Apart from the setting up and verification processes mentioned earlier, there are some other aspects that you might want to know.

Besides template messages, WhatsApp separates session messages — messages that businesses can send to customers during an active 24-hour session window after a customer or a business has initiated contact. During this session window, companies can send customers unlimited messages without additional charges. Once the session window expires, companies should use approved message templates or pay for message charges for each message sent.
