APIs & Third-Party Integration

Project Overview

A middleware integration layer built with Laravel that connects a company's existing ERP, CRM, and e-commerce platforms through a unified API hub — eliminating data silos and manual data entry across departments.

Challenges

The client had five separate systems (ERP, CRM, e-commerce, accounting, and HR) that did not communicate with each other. This caused duplicate data entry, inconsistencies, and reporting delays of up to 3 days.

Solution

Built a Laravel-based API gateway that acts as a central hub. Each system sends and receives data through standardised REST endpoints. A job queue handles async operations so no single system can block another.

Key Features

• Unified REST API hub with OAuth2 authentication
• Bi-directional sync between ERP, CRM, and e-commerce
• Laravel Horizon for job queue monitoring
• Webhook management with retry logic and failure alerts
• Real-time data dashboard for integration health monitoring

Results

Eliminated 100% of manual cross-system data entry. Reporting that previously took 3 days is now available in real time. The integration processes 10,000+ API calls per day without issues.
