Let us help you with API

Today’s logistics operations require more than standalone software and manual processes. Businesses need connected systems, real-time information, intelligent automation, and data that can support AI-driven decisions.

SLG’s API services connect logistics directly with your existing ERP, WMS, e-commerce, accounting, or transportation management platform. They provide the reliable, real-time data foundation needed to automate routine work, improve decisions, and prepare your operation for emerging AI capabilities.

• Retrieve LTL shipping rates from multiple carriers.
• Compare cost, transit time, and service options.
• Apply business rules to help select the best carrier.
• Present shipping options directly within your existing system.

Example: Your ERP can retrieve and compare available freight rates while an order is being processed—without requiring the user to open another application.

• Create shipments directly from your ERP, WMS, or order-management system.
• Submit pickup requests electronically.
• Eliminate repetitive data entry.
• Reduce shipment-entry errors and processing delays.

Example: When an order is ready to ship, your system can automatically send the shipment information to SLG and initiate the booking process.

• Retrieve shipment status and tracking events.
• Monitor pickups, in-transit activity, delays, and delivery.
• Feed status information into dashboards and customer portals.
• Use tracking data to support automated alerts and AI-assisted exception management.

Example: A customer-service portal can display current shipment information automatically, helping reduce routine “Where is my shipment?” calls.

• Generate Bills of Lading electronically.
• Create barcoded pallet or skid labels.
• Print documents directly at shipping locations.
• Improve consistency, accuracy, and warehouse efficiency.

Example: A warehouse system can request the required BOL and labels as soon as an order is released for shipment.

• Retrieve carrier invoice information electronically.
• Compare invoiced charges with quoted or contracted rates.
• Identify unexpected charges and potential billing discrepancies.
• Send validated freight costs to accounting and reporting systems.

Example: An accounting workflow can review freight charges before payment and flag discrepancies for investigation.

APIs and EDI are not necessarily competing technologies. Each serves an important purpose, and many successful logistics operations use both.

EDI remains valuable for standardized transactions such as shipment tenders, acknowledgments, tracking updates, and freight invoices. APIs provide the speed and flexibility required for modern applications, real-time workflows, customer-facing tools, and AI-enabled automation.

AI is only as useful as the information available to it. Disconnected systems, delayed updates, and inconsistent data limit what AI can accomplish.

SLG APIs help create a connected logistics environment where trusted information can move securely between systems. This makes it possible to build smarter capabilities such as:

• Automated carrier recommendations
• Shipment exception detection
• Predictive delivery monitoring
• Freight-cost analysis
• Invoice anomaly detection
• Intelligent customer notifications
• Natural-language logistics reporting

The future of logistics will be driven by connected data, APIs, automation, and AI. SLG helps businesses establish that foundation while continuing to support the proven EDI processes they depend on today.
