How Shipping Aggregators Work in Ecommerce: Complete Guide

A shipping aggregator acts as a centralized technology hub connecting e-commerce sellers with multiple courier and logistics providers. Instead of integrating 10 different courier APIs individually, sellers connect once to an aggregator platform.

Step-by-Step Shipping Aggregator Architecture

• ✓1. Order Ingestion: Orders automatically sync from Shopify, Amazon, WooCommerce, or custom ERPs via API webhooks.
• ✓2. Rate Engine Comparison: The aggregator compares physical vs volumetric weight (L x W x H / 5000) across 6 Indian zones and ranks courier options.
• ✓3. AWB Barcode Label Generation: The system requests waybill numbers from selected courier APIs and generates thermal 4x6 labels.
• ✓4. Automated Pickup Dispatch: Pickup requests are dispatched directly to courier rider handheld devices.
• ✓5. Real-Time Tracking & NDR: Status updates flow into a single unified tracking page while delivery failures trigger WhatsApp NDR recovery.
• ✓6. COD Remittance & Wallet Audit: Delivered COD cash is reconciled against courier payout sheets and credited to seller wallets.
