Problem Statement

E-commerce businesses and local shops struggled to manage high volumes of customer inquiries on WhatsApp manually. Staff couldn't respond 24/7, leading to missed sales opportunities, delayed order status updates, and frustrated customers asking repetitive FAQ questions. Businesses needed an affordable automation solution that could handle conversations at scale while maintaining a personal touch.

Approach & Solution

Designed and executed comprehensive test suites for WhatsApp Business API integration, AI chatbot conversation flows, order status webhook processing, and lead capture workflows. Validated message template approvals, delivery receipts, media handling, and multi-language support. Performed end-to-end testing for e-commerce platform integrations (Shopify, WooCommerce).

Testing Strategy

Collaborated with developers and AI engineers to test conversation flow accuracy, intent recognition, and fallback handling for edge cases. Performed API testing for WhatsApp Cloud API endpoints, webhook signature verification, and rate limit handling. Conducted load testing to ensure platform stability during high-volume campaigns and flash sales.

CI/CD Integration

Integrated automated API tests with Jenkins for continuous validation of message delivery, webhook processing, and AI response accuracy. Set up monitoring for message delivery rates, response latency, and conversation completion metrics. Implemented automated regression tests for each WhatsApp API version update.

Order Status Webhook Notificationjava

@Test 
public void testOrderStatusWebhookNotification() { 
    // Simulate Shopify order status update webhook 
    String orderId = "ORD-" + System.currentTimeMillis(); 
    String webhookPayload = "{"id": "" + orderId + "", "status": "shipped", "tracking_number": "1Z999...", "customer_phone": "+1234567890"}"; 
    String signature = generateHmacSignature(webhookPayload, WEBHOOK_SECRET); 
    
    given() 
        .header("Content-Type", "application/json") 
        .header("X-Shopify-Hmac-SHA256", signature) 
        .body(webhookPayload)
