WhatsApp Business API: all you need to know in 2022

Written byPim de Vos

In 2018, the WhatsApp Business app was launched. The app could only be used by one person at the same time and has limited automation options. That’s why the app was only useful for small businesses.

For mid to large-sized businesses, WhatsApp introduced the WhatsApp Business API. With the API, businesses can manage high volumes of WhatsApp messages, work together with a team, and automate time-consuming workflows.

In this article, we’ll discuss the benefits of the WhatsApp Business API, how to use the right WhatsApp Business Solution Provider, which costs you can expect, and how to get started.

Benefits of the WhatsApp Business API

The WhatsApp Business API enables businesses to manage and answer WhatsApp messages with multiple users.

With the API, you are equipped with a wide variety of features that aren’t available in the app, such as:

  • Notifications (order confirmations, payment requests, appointment reminders, etc.)
  • Automation (auto-replies, quick replies, chatbots, rules)
  • Statistics (response time, resolution time, customer satisfaction)
  • Bulk messages
  • E-commerce integrations with Shopify, WooCommerce, Magento, and Lightspeed
  • The possibility to add WhatsApp to your website as a live chat

One of the biggest benefits of the API is that you can work together with your colleague on answering a question. You can simply @tag each other within a thread, without the customer noticing it.

The 24-hour limit of the WhatsApp Business API

To prevent spam and make sure businesses reply fast to customers, WhatsApp came up with a 24-hour window. This means businesses have 24 hours to reply to messages to customers.

After those 24 hours, businesses can only send a message with a WhatsApp Business template message. Template messages can be sent to either start a new conversation or reply to a customer after the 24-hour window. You can write these templates yourself, but they first have to be approved by WhatsApp before you can send them. For this, they have to fit WhatsApp’s policies.

You can personalize template messages with ‘dynamic fields’, as you can see in the image below.

Choosing the right WhatsApp Business Solution Provider

Using the WhatsApp Business API is a bit more complex than using the regular app. That’s because the API doesn’t come with an interface and can only be accessed via a customer engagement platform like Trengo.

Not every platform can connect to the API. For this, they need to be an official WhatsApp Business Solution Provider (BSP). There are few BSPs worldwide and WhatsApp has high standards of platforms that sign up to become one.

When picking a BSP, it’s advised to take a look at the specific features the platform has. Just because a platform is a BSP, does not mean they offer all the features that the API is capable of.

WhatsApp Business API costs: what you can expect

To calculate the WhatsApp Business costs for your situation, you need to take the following costs into consideration:

  • Setup costs
  • Monthly costs
  • Costs per conversation

The costs always differ per platform.

Setup costs

A couple of BSPs ask for a one-time fee to set up your WhatsApp Business API account. With some BSPs, this number can go up to €1000 (!). Even though this process doesn’t take that much effort for either party.

At Trengo, you pay no setup costs.

Monthly costs

The monthly costs can differ a lot per BSP. Many providers don’t communicate their pricing at all. And others are not an official BSP and offer the API via a third party. This way, you may face unexpected costs. That’s why it’s advised to first research the best solution for your business.

Besides just looking at the costs, it’s also important to research the features every platform offers. For instance: at Userlike, you can build a WhatsApp chatbot with a subscription of €720 per month. At Trengo, you can build a chatbot with a subscription starting at €25 a month.

Costs per conversation

All WhatsApp Business API users pay a fixed price per conversation. A conversation initiated by a customer comes with a different price than a conversation started by a business.

The first 1000 conversations per month are free for all WhatsApp Business API users. The costs per conversation differ per country. In The Netherlands, the costs are
