With billions of users worldwide, WhatsApp has become a powerful platform for businesses to engage with their customers. One of the most effective ways to leverage WhatsApp for business communication is by setting up the WhatsApp API to send automated notifications and alerts. Whether it’s for transactional updates, appointment reminders, or promotional messages, businesses can use the WhatsApp Chatbot to streamline customer interactions and improve engagement.
This article will guide you through the process of setting up the WhatsApp API to send notifications and alerts efficiently. We will cover the key requirements, setup steps, integration methods, and best practices to ensure your WhatsApp notifications are impactful and compliant with WhatsApp’s policies.
Understanding WhatsApp API for Notifications
What is WhatsApp Business API?
The WhatsApp Business API is designed for medium and large businesses to automate communication with customers. Unlike the WhatsApp Business App, which is limited to manual messaging, the API allows businesses to send automated messages, notifications, and alerts through approved templates.
Benefits of Using WhatsApp API for Notifications
- Instant communication: Send real-time updates to customers.
- Automation: Reduce manual workload by setting up automated alerts.
- High engagement: WhatsApp messages have higher open rates compared to emails or SMS.
- Secure and reliable: End-to-end encryption ensures safe communication.
- Seamless integration: Easily connects with CRM systems, ERP software, and WhatsApp Chatbot solutions.
Steps to Set Up WhatsApp API for Sending Notifications
Step 1: Apply for WhatsApp Business API Access
To use the WhatsApp API, businesses need to apply for access through an official WhatsApp Business Solution Provider (BSP) such as:
- MSG91
- 360Dialog
- Wati
- MessageBird
- Infobip
Requirements for API Access:
- A verified Facebook Business Manager account.
- A registered phone number (not already used for WhatsApp Business App).

Step 2: Choose a Business Solution Provider (BSP)
BSPs help businesses connect with the WhatsApp API without handling complex technical configurations. They provide:
- API hosting and maintenance.
- Pre-approved message templates.
- Integration with chatbots and CRM systems.
Step 3: Verify Your Business and Set Up API
Once you have access to the API through a BSP, you need to:
- Verify your business profile on Facebook Business Manager.
- Register a phone number for WhatsApp API use.
- Get API credentials (authentication keys, webhook URLs, etc.).
Step 4: Create and Submit Message Templates
WhatsApp only allows businesses to send pre-approved message templates for notifications. These templates should:
- Follow WhatsApp’s formatting guidelines.
- Not include promotional content (unless permitted).
- Provide clear and concise information.
Example Message Templates:
- Order Confirmation:

Step 5: Integrate WhatsApp API with Your System
Businesses need to integrate the WhatsApp API with their backend systems to automate notifications. This can be done through:
- CRM Integration: Send notifications based on customer interactions.
- E-commerce Platforms (Shopify, WooCommerce): Automate order and shipping updates.
- WhatsApp Chatbot Integration: Allow users to interact with automated responses.
- Zapier or API Gateway: Connect with third-party tools for workflow automation.
Automating Notifications with WhatsApp Chatbot
A WhatsApp Chatbot enhances notification systems by allowing two-way communication. Customers can respond to notifications and get real-time assistance.
1. Setting Up a WhatsApp Chatbot for Notifications
- Choose a chatbot platform (e.g., Twilio, Dialogflow, Chatfuel).
- Design conversation flows based on customer queries.
- Train the bot to handle FAQs, payment updates, and order tracking.
2. Examples of WhatsApp Chatbot Notifications
- Flight Status Updates: “Your flight {{1}} has been delayed by {{2}} minutes.”
- Subscription Renewal Alerts: “Your subscription expires in {{1}} days. Renew now to continue access.”
- Customer Support: “Would you like to speak to an agent? Reply ‘Yes’ or ‘No’.”
3. Using AI and NLP for Smart Responses
Advanced chatbots use AI and Natural Language Processing (NLP) to understand customer queries and respond accurately. For example:
- A customer replies “When will my order arrive?”
- The chatbot pulls real-time order status and responds with delivery details.
Best Practices for Sending WhatsApp Notifications
1. Get User Consent (Opt-in Requirement)
WhatsApp requires businesses to obtain explicit opt-in consent before sending notifications. This can be collected via:
- Website forms
- SMS opt-ins
- In-app pop-ups
- WhatsApp messages initiated by users
2. Personalize Messages for Better Engagement
Using customer names and relevant details improves user engagement. Example:
- Generic: “Your order is confirmed.”
- Personalized: “Hi Sarah, your order #12345 has been confirmed. Expected delivery: May 10.”
3. Optimize Message Timing
Avoid sending messages at odd hours. Schedule messages during appropriate times to ensure higher read rates.
4. Monitor Performance Metrics
Track the effectiveness of WhatsApp notifications using:
- Open rates
- Click-through rates (if using CTA buttons)
- Response rates
- Customer feedback
