What is WhatsApp Business API?
WhatsApp Business API is a powerful messaging platform designed for medium to large businesses that need to communicate with customers at scale.
Unlike the regular WhatsApp app or the WhatsApp Business app (which run on a single phone and are meant for small businesses), the API:
- Connects directly with your CRM, ticketing system, chatbot, or custom software
- Supports multiple agents and devices at the same time
- Enables automation, advanced workflows, and analytics
- Allows proactive messaging using approved templates
In simple terms, the WhatsApp Business API turns WhatsApp into a full‑fledged customer communication channel for marketing, customer support, order updates, and more.
Key capabilities include:
- Automated replies and AI chatbots
- Rich media messages (images, videos, documents, buttons)
- Bulk notifications (within Meta’s policies)
- End‑to‑end encryption and enterprise‑grade security
- Detailed message analytics and reporting
Convex Interactive has used the WhatsApp Business API to:
- Integrate with CRMs and data platforms
- Build custom chatbots and menu bots using tools like Dialogflow and Node.js
- Connect with systems like Salesforce and e‑commerce platforms
- Deliver secure, compliant, and scalable messaging for enterprises

WhatsApp Business App vs WhatsApp Business API
Both the WhatsApp Business app and the WhatsApp Business API are built for business communication, but they serve very different needs.
WhatsApp Business App
The WhatsApp Business app is:
- A free mobile app
- Best suited for small to medium businesses
- Runs on a single phone (with up to 4 additional linked devices)
Key features:
- Business profile with name, description, address, website, and hours
- Quick replies, greeting messages, and away messages
- Basic labels for conversations
- Simple catalog to showcase products/services
Limitations:
- No direct integrations with CRMs, ticketing tools, or databases
- Limited multi‑user and multi‑device scalability
- Manual handling of most conversations
- Difficult to manage multilingual and large‑scale messaging
WhatsApp Business API
The WhatsApp Business Platform (API) is:
- A paid, scalable solution
- Designed for medium and large enterprises
- Built to integrate with your existing systems and software
Key advantages:
- Supports multiple agents and teams working simultaneously
- Connects with CRMs (e.g., Salesforce, HubSpot), helpdesk tools, and custom systems
- Uses approved message templates with rich media and interactive buttons
- Allows proactive, automated, and event‑based messages inside and (where allowed) outside the 24‑hour customer service window
- Ideal for multi‑language and multi‑region customer communication
Here’s the core difference in one line:
The WhatsApp Business app is for basic, manual communication, while the WhatsApp Business API is for automated, integrated, and large‑scale customer engagement.
Key Components of a WhatsApp Business API Setup
To use WhatsApp Business API effectively, several core components work together.
1. WhatsApp Business Profile
A WhatsApp Business Profile is your brand’s identity on WhatsApp. It typically includes:
- Business name and logo
- Description
- Address and location
- Website and social links
- Business hours
A complete, verified profile builds trust and credibility with your customers from the very first interaction.
2. Messaging Tools & Automation
The real power of WhatsApp Business API lies in its messaging capabilities:
- Quick replies for common questions
- Message templates for notifications, alerts, and campaigns
- Chatbots to handle FAQs and repetitive queries
- Routing and assignment to different agents or departments
- Multi‑user access so teams can collaborate efficiently
With the right setup, businesses can combine human agents and AI chatbots to provide fast, consistent, and personalized responses.
3. Analytics & Reporting
WhatsApp Business API provides data and insights such as:
- Message delivery and read rates
- Response times
- Active conversation volumes
- Agent and chatbot performance
These analytics help you:
- Measure the effectiveness of your communication
- Optimize templates and conversation flows
- Identify gaps in support and customer experience
Tools like BerryTalks enhance this further with real‑time dashboards and performance reports.
4. Integrations
The API is designed to plug into your existing technology stack:
- CRM systems (Salesforce, HubSpot, custom CRMs)
- E‑commerce platforms (for order updates, tracking, re‑orders)
- Marketing automation tools
- Customer data platforms (CDPs)
- Chatbot platforms and AI engines (e.g., Dialogflow)
With secure webhooks and cloud hosting, Convex Interactive connects WhatsApp with enterprise systems to create end‑to‑end automated journeys.
How WhatsApp Business API Pricing Works
The WhatsApp Business API uses a conversation‑based pricing model. Businesses are charged per 24‑hour conversation window, and the cost depends on the type of conversation.
Meta currently defines four main conversation categories:
1. Marketing
- Promotions, offers, updates, and awareness campaigns
- Example: “Get 20% off on your next order – tap to shop now.”
2. Utility
- Transactional messages and updates
- Example: Order confirmations, shipping updates, invoices, alerts
3. Authentication
- One‑time passwords (OTPs) and verification codes
- Example: Login verification, account security OTPs
4. Service
- Customer‑initiated conversations for support or inquiries
- Example: Customer messages you about an issue, and your agents respond
Within each 24‑hour session, you can send multiple messages as part of that conversation.
Note: Exact pricing depends on your region and the Business Solution Provider (BSP) you work with. Rates are set by WhatsApp/Meta and can vary by country and conversation category.
If you need country‑specific pricing, Convex Interactive can guide you and provide local‑currency billing through our WhatsApp Business API solutions.
For detailed, region‑specific pricing and implementation options, you can visit our dedicated WhatsApp Business API service page.
How WhatsApp Business API Works: Architecture & BSPs
The WhatsApp Business API does not work like a simple app you download. It is a server‑side integration that requires hosting, configuration, and compliance.
At a high level, the flow looks like this:
Customer ↔ WhatsApp ↔ Meta/WhatsApp Servers ↔ Business Solution Provider (BSP) ↔ Your Systems (CRM, Bot, Agents)
What Are WhatsApp Business Solution Providers (BSPs)?
Business Solution Providers (BSPs) are authorized partners of Meta that:
- Provide access to the WhatsApp Business API
- Offer hosting and infrastructure (cloud or on‑premise)
- Help you manage message templates and approvals
- Provide dashboards, interfaces, and tools for agents
- Assist with compliance, security, and onboarding
Because the raw API is technical and infrastructure‑heavy, most businesses work through a BSP instead of integrating everything from scratch.
