    REVOLUTIONIZE YOUR ONLINE BUSINESS WITH SHIPPING API

    Start Your Integration Now and Unlock Faster, Automated Logistics

    shipping api integration

    Inefficient shipping and tracking processes often become hidden bottlenecks that hinder eCommerce growth, slowing fulfillment, introducing human error, and decreasing customer satisfaction. This is especially critical, given that 31% of U.S. consumers stop doing business with a brand after a single bad delivery experience, defining the high cost of these inefficiencies. At PLANEKS, we provide advanced eСommerce shipping API integration services that bring automation, accuracy, and transparency to every stage of fulfillment. Our engineers connect your system with top carriers like FedEx, UPS, DHL, and USPS, enabling real-time label generation, dynamic tracking updates, and seamless communication with delivery partners.

    Our eCommerce Shipping API Integration Services

    Modern eCommerce success heavily depends on how efficiently businesses can move products from the warehouse to customers’ doorsteps. PLANEKS helps you achieve this with fully streamlined, API-driven shipping ecosystems that eliminate manual bottlenecks, reduce operational costs, and deliver exceptional end-user experiences. Our eCommerce shipping API integration services are designed to enhance your logistics processes, making them faster, manageable, and more transparent, regardless of the number of carriers, warehouses, or platforms you operate.

    Multi-Carrier API Integration

    Through multi-carrier API integration, PLANEKS connects your eCommerce platform with global shipping providers, including FedEx, UPS, DHL, and USPS. This enables flexible delivery options and automated carrier selection based on package size, destination, and delivery speed. Instead of logging into multiple portals, your team manages everything through one source of truth. We ensure resilient architecture that provides instant synchronization of tracking numbers, delivery statuses, and service levels, allowing your operations to scale across multiple regions.

    Order & Fulfillment Integration

    PLANEKS’ fulfillment API integrations synchronize orders seamlessly from your eCommerce stack, adapting to both ready-made platforms and bespoke architectures. Once an order is placed, the system automatically triggers the creation of packing slips, shipment, and label generation. Through automation, you efficiently eliminate repetitive manual work, reduce human error, and speed up the fulfillment cycle. As an outcome, warehouse teams can process more orders with the same resources while maintaining consistent accuracy and timely dispatch.

    Tracking & Notifications APIs

    Customer expectations today focus on transparency, particularly when it comes to knowing exactly where their order is. With PLANEKS, you can build shipping API integration solutions so that your customers receive real-time delivery updates and live tracking information without leaving your platform. The integration can support push notifications, email updates, and status changes directly synchronized with carrier systems. This enhances both the post-purchase experience and reduces customer service requests related to order status, allowing your support teams to concentrate on higher-value interactions.

    Label Generation APIs

    Generating and printing shipping labels manually introduces unnecessary latency and significantly increases the risk of data-entry mistakes. To avoid such challenges, our qualified team integrates carrier label APIs that automate label creation within your existing dashboard, streamlining the process. Each label covers precise routing and tracking details generated in accordance with the carrier’s specifications. Thus, you can shorten dispatch times and ensure compliance with each courier’s operational standards, improving delivery efficiency.

Automated customs handling and live tracking significantly reduce delays, improving international shipping efficiency.

    USPS

    For businesses shipping within the United States, our USPS API integration for eCommerce shipping automates domestic label printing, shipment creation, and tracking synchronization.

    OUR SOLUTIONS

    Shipping Aggregators & Platforms

    To maximize flexibility and efficiency in logistics, modern eCommerce businesses often rely on shipping aggregators – platforms that retrieve multiple carriers through a single API. PLANEKS integrates these robust systems to help you automate fulfillment, optimize rate management, and provide immediate visibility across every shipment. By leveraging platforms such as Shippo, EasyPost, ShipStation, and AfterShip, we build seamless, scalable ecosystems that eliminate the need for multiple carrier integrations while maintaining in-depth operational control.

    Shippo API Integration

    Through our Shippo API integration, PLANEKS connects your eCommerce backend to a broad range of carriers, enabling automated label generation, live rate comparisons, and bulk shipment processing. The integration streamlines multi-carrier logistics, allowing you to manage all shipping operations from a single interface. Businesses gain faster order fulfillment, reduced operational overhead, and consistent delivery accuracy regardless of carrier or destination.

    EasyPost API Integration

    EasyPost API integration provides unified carrier access, real-time tracking, and automated label creation within your existing infrastructure. PLANEKS ensures a smooth and secure implementation that supports large-scale eCommerce and marketplace environments. With EasyPost, your team can instantly generate labels, verify addresses, and retrieve live shipping rates, optimizing delivery speed and cost efficiency through a single, standardized endpoint.

    ShipStation API Integration

    ShipStation API integration for eCommerce shipping can automate every step of the fulfillment process from importing orders to printing labels and updating tracking information. It connects directly with leading platforms, including Shopify, WooCommerce, and Amazon, enabling businesses to handle high-volume shipments with minimal manual intervention. This elevates delivery accuracy, warehouse coordination, and customer communication, resulting in a well-orchestrated fulfillment process.

    AfterShip API Integration

    PLANEKS leverages AfterShip API integration to enhance post-purchase visibility and customer satisfaction. By synchronizing real-time tracking updates and automated notifications, businesses can cohesively communicate shipment progress and reduce support requests. This integration delivers transparency and trust, which are the critical factors for improving retention and brand reputation.
