What is WhatsApp business API?

The WhatsApp Business API emerges as a standout player when navigating the vast landscape of business communication tools. At its core, it’s a digital bridge designed by Meta (formerly Facebook) in 2018. It connects businesses to the vast world of WhatsApp users, enabling a seamless exchange of messages and interactions. But it’s not just a simple message relay system; it’s an innovative solution for medium to large businesses looking to engage with their audience at scale.

So, what exactly is it? The WhatsApp Business API acts as a backend mechanism that allows businesses to manage and automate their conversations on WhatsApp. Instead of a tangible app or interface that one might use on a personal device, the API is integrated into other messaging platforms or systems businesses already use. The objective? To handle multiple conversations, craft personalized dialogues, and facilitate automated responses—all within the trusted space of WhatsApp.

Although one might consider setting up the API through Meta, platforms like Yellow.ai, have made the process more accessible and intuitive. With their tools and dashboards tailored for businesses, Yellow.ai simplifies the WhatsApp API experience. It’s less about getting lost in technicalities and more about harnessing the real power of the platform to foster genuine connections with customers.

You might hear some folks referring to it as the “WhatsApp Business Platform” from 2023 onward, courtesy of a rebranding exercise by Meta. But regardless of the name, its core purpose remains—to revolutionize business communication in today’s digital age.

4 Reasons for shifting to WhatsApp business

Building on the growing momentum of conversational marketing, integrating the WhatsApp Business API into your business model might seem like the next logical step. But beyond the technicalities and the sheer vastness of WhatsApp’s user base, why should businesses consider this transition? Let’s dive into the compelling reasons:

Reasons for Shifting to WhatsApp Business

1. Unmatched open rates

Email marketing has its merits, but WhatsApp takes the crown to ensure your message is seen. With an astonishing 98% message open rate, WhatsApp dwarfs the open rates of emails, which typically hover between 15-25%. Almost every message you send on WhatsApp gets noticed, and you aren’t lost in a crowded inbox. (Source)

2. Tailored customer interactions

The essence of marketing is understanding and connecting with your audience. WhatsApp Business facilitates personalized customer experiences. By understanding your audience’s preferences and behaviors, businesses can craft messages that resonate more deeply and drive meaningful engagement.

3. The vastness of reach

We’ve touched on it before, but it’s worth reiterating – 2.78 billion people are active on WhatsApp. That’s billions of potential customers, partners, and stakeholders at your fingertips. Leveraging WhatsApp Business ensures you cast a wide net in your marketing and communication endeavors.

4. Cost-effective global outreach

In a digital era where marketing costs can skyrocket, WhatsApp provides a breath of fresh air. Reaching out to a global audience doesn’t require a hefty advertising budget. With merely a smartphone and a stable internet connection, businesses can initiate conversations, foster relationships, and drive conversions without burning a hole in their pockets.

Embracing WhatsApp Business API is not just about jumping on a trend but strategically positioning your business to connect, engage, and thrive in a digitally-driven marketplace.

Who can use the WhatsApp business API?

As we traverse the digital pathways of effective business communication, it’s natural to ponder if the WhatsApp Business API aligns with your company’s needs and constraints. Before commencing the journey, it’s essential to understand if your business aligns with the stipulations set out by WhatsApp. 

Here’s a streamlined guide to help you decipher whether the WhatsApp Business API is a good fit:

1. Business size

Small businesses, typically those with a close-knit team of up to 5, might find solace in the cozy confines of the free WhatsApp Business app. But, as your clientele grows and their incessant pings become the soundtrack of your operations, the WhatsApp Business API beckons. It’s the go-to choice for medium to large enterprises, effortlessly balancing multiple conversations.

2. Communication volume

If your business messages are more like a steady stream than occasional raindrops, it’s a sign to look towards the WhatsApp Business API. It not only allows you to send messages en masse, but with chatbots in the mix, automated replies become a breeze. 

Picture this: A customer queries about an upcoming sale, and voila! Your chatbot, armed with predefined responses, provides the details instantaneously.

3. Industry type

While sectors such as telecommunications, real estate, and travel can freely harness the power of the WhatsApp Business API, some industries face a red light. Due to WhatsApp’s robust commerce policy, businesses involved in adult entertainment, gambling, or arms sales are kept at arm’s length. So, before jumping in, ensure your industry gets the green signal.

4. Compliance and messaging templates

In industries where regulations cast a long shadow, like healthcare or finance, messaging can’t be a shot in the dark. The WhatsApp Business API offers pre-defined templates that are in line with standards. Imagine you’re a financial consultant. Updating clients about their stock portfolio status with these templates is as smooth as swiping right on a chat.

How to get started with WhatsApp business API?

After deciphering whether WhatsApp Business API and your enterprise are a match made in digital heaven, the next chapter of our journey nudges us toward the actual setup. The process to access the WhatsApp Business API isn’t a mere click-and-start affair but rather a sequence of intentional steps. Let’s peruse this together, ensuring each step is clear, concise, and, most importantly, actionable.

How to get WhatsApp Business API?

Step 1. Apply for WhatsApp Business API

To jumpstart the process, lean on one of WhatsApp’s approved Business Solution Providers. These trusty partners are like your techy friends who help set up your new devices. Among them, Yellow.ai shines bright, ensuring your application journey is as breezy as a walk in the park.

Apply for WhatsApp Business API

Kick-off by ensuring you have a Facebook Business Manager ID. This ID should be adorned with a verified number and display name. If you’re wondering, “What’s a Business Manager ID?” don’t fret. Simply create a Facebook Business Manager page. Think of it as setting up a digital storefront:

  • Swing by the Facebook Business Manager and hit ‘Register’ to set up your account.
  • Navigate to ‘Business Settings’ and pick the ‘WhatsApp account’ option from the accounts section.
  • Fill out the basics: name, time zone, currency preferences, payment methods, P.O. number, website URL, industry, use case, region of operation, company headquarters’ country, and your Facebook Business Manager ID. 
  • Oh, and don’t forget the verification number—they’ll ping you with a code on your business contact.
  • Punch in that verification code, and give yourself a mini-celebration.

But we’re not done just yet. Next, you’d want to ensure your business name isn’t just a fancy moniker but a legit, verified entity.

Apply for WhatsApp Business API

Step 2. Provide basic information

So, imagine you’re at a mixer and introducing your business to a room full of potential partners. You’d want to share the basics, right? Similarly, feed some elementary information about your enterprise to set up your WhatsApp Business Account.

Here’s a brief list of documents you’d need:

  • Incorporation Certificate or Articles
  • A valid business license or registration document
  • Government-issued business tax documents (nope, self-filed ones won’t make the cut)
  • A recent business bank statement
  • Utility bills showcasing the legal business name

If these are in a language not part of the Meta-supported list, just ensure they come with a certified English translation. You can check the supported languages for business verification from the Meta Business Help Centre page. And remember, a stamp from a translating agency is vital.

Acceptable documents for business address verification:

  • Utility bill
  • Bank statements or business bank account statements
  • Business licenses
  • Certification of formation or incorporation
  • VAT registration or Business Tax certificate
  • EIN Confirmation letter from IRS 
  • Federal Tax returns to the IRS
  • Business credit report from one of the reporting agencies

A heads-up, though: Sometimes, Facebook might take its sweet time (around 2-3 weeks) to churn through these details.

Step 3. Activate phone number for WhatsApp Business account

With the foundation firmly in place, let’s breathe life into your WhatsApp Business Account by activating your chosen phone number. Whether it’s a number with you since day one or a fresh string of digits, the choice is yours. Upon the green light from Facebook, it’s time to finesse your WhatsApp profile.

Here’s where your business’s display name, category, description, and product listing step into the limelight. Each detail should reflect your brand, ensuring consistency and recognizability in every customer interaction. You can give these details to Yellow.ai, and we will finish setting up the API for you. 

While it may seem like a flurry of steps and documents, remember: the goal isn’t just about creating a profile. It’s about building a bridge to over 2.78 billion potential conversations, each a pathway to a customer, partner, or opportunity.

And there we have it—a straightforward, no-frills guide to getting started with WhatsApp Business API.

WhatsApp API vs. WhatsApp business app

In the vast universe of WhatsApp, while the primary app caters to personal conversations, two luminous stars are dedicated to businesses—the Business App and the Business API (Platform). The duality is designed to be complementary rather than contradictory. Still, with their unique quirks, capabilities, and price tags, it’s essential to understand where each fits snugly in the business tapestry. Let’s explore and differentiate these two realms of WhatsApp’s business solutions.

Below, find a table that paints a clear and concise picture, helping you navigate the intricate dance between the two:

Whether starting afresh or working with an existing list, ensure you have a well-segmented list of contacts ready to receive your WhatsApp notifications.

WhatsApp Business API pricing

Let’s get down to the nitty-gritty of WhatsApp Business API: the cost. Unlike the free WhatsApp Business App, the price tag can swing a bit based on what perks your chosen Business Solutions Provider offers. Book a demo if you want to know how Yellow.ai fits the equation. Our team’s always game to walk you through.

Here’s the lowdown on costs:

1. Conversation cash

Freebies alert! Your initial 1000 support chats every month? On the house. It means many small to medium-sized ventures might never see an additional charge. However, after crossing that threshold, WhatsApp charges for every new conversation. Head to Meta’s Rate Cards section for the most up-to-date pricing across various regions and currencies.

A new session is initiated after the 24-hour window of an active chat. Pricing nuances exist based on location, category, and who initiated the chat. In the U.S.? Expect about 1 cent for customer-started chats and 1 to 2 cents for those sparked by businesses. 

And here’s a pro tip: You’re billed only when you reply, so there are no charges for letting those unwanted messages sit.

2. Two conversation types to know

  • User-Initiated Conversations (UIC): These conversations kick off when a business responds to a user within the 24-hour window. Picture your standard customer support chats. In the U.S., these typically hover around 8 cents.
  • Business Initiated Conversations (BIC): These take the stage when businesses reach beyond the standard 24-hour window. But, a templated approach is necessary for BICs. Whatsapp categorizes BIC into: 
  • Utility: Think essential, functional messages, costing roughly 2 cents in the U.S.
  • Authentications & Marketing messages: Both generally run about 1 cent.

Leveraging WhatsApp business API

Let’s get real: the WhatsApp Business API isn’t just another digital tool—it’s the MVP of your business communication toolkit:

  • Support team: Consider it the secret sauce, turning your support team from casual chatters to chat champions. It’s like having a coffee chat with your customers, but online. Cozy, direct, and authentic.
  • Analytics: Dive deep, get curious and become best friends with your data. See what ticks with your customers and what doesn’t. Adjust, refine, and win at messaging.
  • Sales & marketing team: Imagine having a mega speaker to share your brand stories. Broadcast those tantalizing offers and let the magic of engagement drive those numbers up.

The final thoughts on WhatsApp Business API

Venturing into the WhatsApp Business API realm is akin to trading in those old roller skates for a pair of turbocharged rollerblades. Speed up, keep it personal, and make every conversation count. And if you’re a medium to large business? It’s not just a plus; it’s a game-changer.
