Amazon API Integration for Logistics Firm

UK logistics company was spending too much time manually managing Amazon orders. Their team had to copy information between spreadsheets and emails just to generate shipping labels and track deliveries — a slow and error-prone process.

Merto Software Solutions helped streamline it all by building a custom API integration with Amazon’s Selling Partner API (SP-API). We connected their internal system directly to Amazon, so they could automatically pull in order details, generate compliant shipping labels, and sync tracking statuses in real-time.

The system was built for long-term reliability and security, deployed on their internal infrastructure using modern tools that make it easy to maintain and scale as their business grows.

Key Features of the Project:

• Amazon SP-API Integration: Real-time syncing of order data and shipping labels.
• Automated Label Generation: Fetch and store Amazon-compliant shipping labels directly.
• Shipment Status Syncing: Track fulfilment and update local records automatically.
• Secure Authentication: Role-based access and secure token handling.

Technologies Used:

• React & Next.js: For building secure internal admin interfaces.
• AWS Lambda & S3: For scalable serverless functions and label storage.
• Next.js API Routes: For handling backend logic and securely communicating with Amazon’s APIs.
• Amazon SP-API: For order retrieval and shipment creation.

Results:

• Reduced Manual Handling: Shipment creation time dropped by 60%.
• Real-Time Visibility: Orders, labels, and tracking synced instantly.
• Operational Efficiency: Less admin work and fewer fulfilment errors.
