Application Programming Interfaces (APIs) are revolutionizing how systems communicate across the supply chain. APIs allow inventory systems, order management platforms, and transport systems to sync instantly. This real-time interoperability redefines supply chain management by eliminating delays caused by batch processing or data silos. APIs enable smoother collaboration between vendors, customers, and logistics providers. Businesses can update inventory levels across platforms in real time, track shipments instantly, and automate reorders. Modern supply chain leaders must now understand integration architecture and tech ecosystems. APIs are the glue binding modern logistics.
