What is the WhatsApp Business API?
The WhatsApp Business API is the professional version of WhatsApp for businesses. Unlike the regular WhatsApp Business app, the API supports multiple agents, automation, and integrations with other systems.
The standard WhatsApp Business app works fine if you work solo and handle a handful of messages per day. But as soon as your team grows or you manage more than a few conversations at once, you hit limitations. The API solves those problems.
With the WhatsApp Business API, you can connect an AI chatbot that automatically responds to incoming messages. Ideal for frequently asked questions, first-touch interactions, and service outside business hours.
Why SMBs need the API
Customers increasingly expect to reach you via WhatsApp. With the standard app, only one person can respond at a time. The API allows multiple team members and a chatbot to be active simultaneously.
On top of that, the API offers automation capabilities. Think automatic greetings, quick answers to common questions, and seamless handoff to a human agent when needed.
The difference between template and session messages
The WhatsApp Business API has two types of messages. Session messages are replies within an active conversation started by the customer. These messages are free and flexible in content.
Template messages are pre-approved messages you can send outside an active conversation. Think appointment confirmations or shipping notifications. Heyloha's WhatsApp agent responds only to incoming messages. It does not send proactive or bulk messages.
Setting up with Heyloha: step by step
Setting up the WhatsApp Business API with Heyloha takes four steps. First, you connect your WhatsApp Business account. Next, you configure the tone of voice and knowledge bank. The chatbot learns from your website automatically.
Then you set escalation rules: when should the conversation be handed off to a human agent? Finally, you go live. The entire process takes about 30 minutes and requires no technical expertise.
You can keep using your existing phone number. There is no need to get a separate one.
Frequently asked questions
Do I need a separate phone number? No, you can use your existing business number. Can the chatbot use my website as a source? Yes, it learns from your website content automatically and adapts to your tone of voice.
Does the chatbot proactively message customers? No. Heyloha's WhatsApp agent only responds to incoming messages. It does not send proactive or bulk messages. When the chatbot cannot handle a conversation, it is handed off to a human agent.
