How to Use WhatsApp Business API: The Guide Need-to-Know to Getting Started

In the fast-paced digital age, businesses need to connect with customers in real time. That's when the WhatsApp Business API proved valuable. It's not only about texting anymore—it's about trust, instant care, and a smooth customer journey.

Whether you are a new startup or an established brand, if you are considering leveraging WhatsApp to reach customers through your website or Facebook page, then this guide is for you.

‍What is WhatsApp Business API?

The WhatsApp Business API is for medium to large-sized businesses that want to manage thousands of customer conversations daily—automatically, at scale, and securely. Unlike the free WhatsApp Business app, the API has far more robust features and flexibility.

With it, they can:

• Send order confirmations, delivery notifications, and reminders
• Provide 24/7 customer support through automation
• Reach more customers at a lower cost with bulk messages
• Establish trust with verified business profiles

How Do You Put WhatsApp on Your Website?

Having WhatsApp on your website allows visitors to initiate a conversation with your team in one click—no waiting, no forms.

1. Place a WhatsApp Chat Button or Link

This is the easiest way to begin. Include a 'Chat with us on WhatsApp' button on your site. When clicked, they're brought directly into a chat with your business in WhatsApp.

It is accessible on both mobile and desktop. Visitors can message you immediately without having to manually add your number.

2. Utilize a Floating WhatsApp Widget

Most companies now employ a floating chat icon on all pages of their website. It remains visible in a corner, enabling users to contact you at any point during their visit.

This is an excellent method to:

• Boost inquiries
• Assist customers while browsing
• Demonstrate you're available and approachable

Widgets are usually personalized with business hours, a welcome message, and even agent names.

‍Can You Link WhatsApp to Your Facebook Page?

Yes—and in 2025, it's simpler than ever.

Because WhatsApp is owned by Meta (also the owner of Facebook and Instagram), the platforms are built to cooperate.

Here's How You Can Do It:

1. Add WhatsApp to Your Facebook Page

Pair your WhatsApp Business number with your Facebook business page. This allows visitors to message you on WhatsApp by clicking a "Send Message" button.

This quick, simple solution gives your business a modern, professional image.

2. Use Facebook or Instagram Ads With a WhatsApp Button

Want to attract new consumers? Create ads that drive customers straight to a WhatsApp conversation with your business. When your ad appears and a person taps the button, they can ask questions, receive product information, or purchase—all via WhatsApp.

This form of advertising is particularly beneficial for:

• Increasing leads
• Responding to questions in real-time
• Encouraging more conversions from social media

‍What Should You Know Before Getting Started

Here are a few things to remember before you apply for the WhatsApp Business API:

It's for businesses, not individuals or personal use

• You'll have a verified Facebook Business Manager account
• You have a dedicated phone number that is not already being used on a regular WhatsApp account
• To make use of the API, you need to collaborate with an official WhatsApp Business Solution Provider (BSP)—such as GreenAds Global
