What is WhatsApp Business API?
Let’s start simple.
If you are confused or want to know what is WhatsApp Business API then you are right pleace. It is a communication tool made for medium and large businesses. It allows companies to connect with customers on WhatsApp at scale – not from a phone, but through a software interface (API) that links WhatsApp with CRMs, websites, and automation systems.
In short:
“The WhatsApp Business API is like giving your business a verified, automated WhatsApp brain – one that can handle thousands of chats every day without a phone in hand.“
How It’s Different from the WhatsApp Business App
Many small businesses use the WhatsApp Business App, which runs on a single phone.
It’s great for manual chatting — but once messages grow, it can’t scale.
The API version is built for teams and automation.
You can:
- Send bulk notifications or OTPs
- Allow multiple agents to reply to customers
- Integrate chatbots and CRM tools
- Access analytics and delivery reports
Why Companies Use It
Businesses use the WhatsApp Business API to:
- Reach customers instantly on their favorite messaging app
- Send order updates, invoices, reminders, and alerts automatically
- Provide 24/7 support with bots and human agents
- Build customer trust with the green tick verification badge
How WhatsApp Business API Works
After understanding what WhatsApp Business API now, we are explaining how it will work. WhatsApp doesn’t offer the API directly to everyone.
You need to go through a WhatsApp Business API Services Provider – like Siratel Communications — to get access and integrate it safely.
1. Connecting Your Business Number
Your WhatsApp Business number is connected to the API through Facebook Business verification.
Siratel helps you with:
- Business Manager verification
- WhatsApp Business Account setup
- API connection with your CRM or tool
Once connected, your business can send messages directly through dashboards, software, or even code-based systems.
2. Sending and Receiving Messages Automatically
With the API, messages aren’t sent from a mobile app — they’re sent through automated systems.
For example:
- When a customer places an order, the API sends a confirmation instantly.
- When payment is pending, it triggers a reminder message.
- When a lead fills a form, it sends an auto-reply within seconds.
3. Using Templates for Alerts, OTPs, and Offers
WhatsApp requires message templates for business-initiated chats.
You can use approved templates for:
- OTPs and login codes
- Appointment reminders
- Payment and order updates
- Offers and festive greetings
Siratel helps you create, format, and get these templates approved quickly.
