What This Is
We build custom integrations with the WhatsApp Business Platform API that bring automated messaging, template notifications, and conversational workflows into your application. Instead of managing WhatsApp conversations through the phone app or a standalone platform, messages flow through your business systems where they can be automated, tracked, and connected to customer records.
The WhatsApp Business Platform (formerly WhatsApp Business API) enables businesses to send template messages (pre-approved notifications), receive and respond to customer messages, and build interactive conversational flows with buttons, lists, and media. We integrate this into your application so that WhatsApp becomes another communication channel managed alongside email, SMS, and in-app messaging.
These integrations are built on the same messaging patterns we use with Twilio in production. The approach covers service layer abstraction, queue-based dispatch, and webhook processing for inbound messages. WhatsApp has specific requirements (template pre-approval, 24-hour messaging windows, opt-in compliance) that the integration handles by design.
When You Need This
WhatsApp Business API integration makes sense when your customers expect to communicate with you through WhatsApp and you need that communication managed inside your application. Common scenarios:
- You need to send transactional notifications via WhatsApp (order confirmations, appointment reminders, delivery updates, or payment receipts)
- Customer support conversations happen on WhatsApp and you need them logged, routed, and connected to customer records in your system
- You want to build interactive flows such as product catalogues, booking confirmations, or FAQ bots that guide customers through structured conversations
- Your market or customer base prefers WhatsApp over email or SMS for business communication
- Marketing campaigns need WhatsApp as a channel, with template messages sent to opted-in contacts
How We Work
WhatsApp integration projects start with message flow mapping, identifying every type of message your application needs to send and receive and categorising them according to WhatsApp’s rules. Template messages (outbound, pre-approved) and session messages (replies within the 24-hour window) have different capabilities and approval requirements.
We handle template creation and approval as part of the integration. WhatsApp requires pre-approval for template messages. The content, variables, and formatting must be submitted to Meta for review. We design templates that are flexible enough for your use cases while meeting Meta’s approval criteria.
The messaging service layer handles outbound dispatch through queue jobs, inbound webhook processing for received messages, and the 24-hour session window logic. When a customer messages you, your application has 24 hours to respond with free-form messages. After that window, only pre-approved template messages can be sent. The service layer manages this timing automatically.
What You Get
- Template message dispatch: pre-approved notifications sent programmatically for orders, appointments, payments, and alerts
- Inbound message handling: customer messages received via webhook, parsed, and routed to the appropriate handler in your application
- Interactive messages with buttons, list menus, and quick replies for structured conversational experiences
- Media support to send and receive images, documents, and location data through WhatsApp conversations
- Session management with automatic handling of the 24-hour messaging window and template fallback
- Conversation logging with full message history stored in your application and linked to customer records
- Opt-in compliance covering user consent management for marketing messages as required by WhatsApp’s policies
Technologies We Use
- WhatsApp Business Platform API: via Meta’s Cloud API for message sending, receiving, and template management
- Laravel: messaging service layer with queue-based dispatch, webhook processing, and session window management
- PostgreSQL: conversation history, template records, opt-in status, and message delivery tracking
- Queue workers: message dispatch and inbound processing handled asynchronously for reliability
Related Systems
WhatsApp integration is a communication channel inside broader customer-facing systems. This sits within our wider API Integrations practice, alongside Twilio API Integration for SMS and voice. Common implementations include a CRM tracking multi-channel conversations, a booking system sending appointment reminders, or a client portal where customers can initiate support conversations.
