Finding the Best Shipping API for eCommerce

If you are in the process of setting up an eCommerce store, it's essential to have a reliable shipping API integrated into your website to ensure efficient delivery. By integrating a shipping API into your checkout system, you can provide customers with accurate and up-to-date shipping options and easily calculate freight costs during the purchase process. With this invaluable information, customers know exactly what they'll be paying for and can finalize their orders on time.

Choosing the right API is vital in maximizing efficiency while ensuring customer satisfaction — but how do you choose? Here, we'll examine the function of a shipping API for eCommerce, take a detailed look at choosing the best shipping API for your eCommerce business, and examine available features such as real-time tracking capabilities.

What Is a Shipping API for eCommerce?

A shipping API for eCommerce is a powerful cloud-based solution that simplifies the process of shipping products to customers. It provides merchants with automated shipment processing, real-time tracking capabilities, and cost savings on shipping. With this technology, merchants can quickly manage their entire shipping process from start to finish, eliminating manual paperwork and errors. 

Moreover, businesses can create custom shipping rules based on their needs, allowing them to customize the service according to their requirements. Shipping APIs also provide greater transparency, allowing merchants to see every step of their shipment process and track the progress of orders in real-time. This allows them to provide better customer service, as they are always aware of order status updates. 

How a Shipping API for eCommerce Works

It is no secret that eCommerce businesses rely heavily on efficient shipping practices. Before a customer makes an online order, they need to know about the options for shipping their product. The need to feel in control contributes a lot to their experience with an online brand. Once the order is placed, the need for a continuous flow of information about the order and its status is crucial.

Here's where a shipping API comes in. A shipping API allows online stores to integrate with the shipping provider's website and give customers real-time information about their product's whereabouts.

Shipping APIs allow these businesses to streamline processes and ensure customers receive orders on time. Shipping APIs work by connecting a business to the various shipping carriers they trust and allowing them to automatically generate labels and tracking information for their orders.

Shipping APIs are connected to existing eCommerce tech stack, enabling data to flow between the platform and carriers. Businesses can receive real-time tracking information for their orders, which allows them to easily update their customers. They also allow integration with multiple carriers, which gives businesses more flexibility and control over the shipping process. This saves businesses time and money and ensures that customers receive their orders on time.

What Are Shipping API Integrations?

Shipping API integrations are a type of shipping software that can be integrated into existing systems, such as eCommerce stores, shipping carriers, and warehousing systems. This integration allows businesses to automate their processes, streamline data exchanges between different platforms, and save time by eliminating manual input of orders and tracking packages.

They enable business customers to access and compare shipping rates and tracking information from a unified interface, ensuring accurate shipment information is sent to the customer quickly and efficiently.

The goal of any API integration is to provide users with fast and easy access to shipping data, enabling them to make better decisions regarding their shipping needs. With the help of shipping API integrations, businesses have access to reliable and up-to-date shipping information from multiple sources. This helps companies provide customers with timely and cost-effective shipping options.

How to Choose a Shipping API for eCommerce

There are various shipping APIs available for eCommerce businesses, and it can be difficult to determine which one is right for you. With many similarities between the options, it's important to do thorough research and consider your business's specific needs to make the best decision.

Here are some things you should think about when choosing a shipping API for eCommerce:


Customization allows businesses to tailor the shipping experience to their unique needs and goals. With a customizable shipping API, companies can easily adjust the features that suit their business, such as custom shipping rules engine, weight and dimensional calculations, customer notifications, order tracking, and much more.

Customization enables businesses to deliver a seamless customer experience while improving the accuracy and efficiency of their order fulfillment process. 


Ensuring the shipping API you choose is compatible with your existing tech stack is crucial. This includes other online services you use to run your business, such as payment systems, checkout experiences, and customer relationship management (CRM) platforms.

Compatibility also means ensuring the shipping API you choose works with your eCommerce platform and integrates efficiently with your store workflow. A good shipping service can also adapt over time as you change and scale your eCommerce.


Although shipping costs vary from one provider to another, a good shipping provider should offer competitive pricing and discounts on bulk orders. They should offer flexible pricing that scales with your eCommerce business needs. Beware of hidden costs, such as delivery charges, fuel surcharges, and other incidental costs.

These can add up quickly and make the shipping cost higher than expected. While it's important to consider low-cost providers, ensure you don't sacrifice quality and reliability.


Does the API offer multiple carrier options? Are there tracking numbers for all shipments? Is there a signature confirmation for packages? Does the API offer real-time shipping rates and delivery projections? Does the API offer international shipping support? Does the API integrate with existing eCommerce platforms and shopping carts? Does the API support batch shipping label creation and printing?

These are some features you should consider when choosing a shipping API for your eCommerce needs.

Level Customer Support

Look for companies that provide 24/7 customer support with a team of knowledgeable and experienced representatives. This will help you with any problems or queries with your shipping API. With a good customer support team, you can quickly raise and troubleshoot issues, ensuring a smooth process for your eCommerce business.

Furthermore, customer support representatives can guide you through the entire setup process and help get your shipping API running smoothly.

Reliability & Security

Shipping APIs with reliable and secure infrastructure ensure orders are delivered promptly and all customer data is protected against unauthorized access. The API should have features such as authentication, encryption, and authorization to ensure secure data transfer.

Additionally, the API should have mechanisms in place to detect and respond to suspicious activity.

The Role of Shipping APIs in eCommerce

Shipping APIs play a significant role in eCommerce. They are responsible for connecting the merchant's software applications to infrastructure services provided by carriers. The following are the key roles of shipping APIs in eCommerce:

Global Address Validation

Shipping APIs can verify, format, and standardize valid addresses worldwide. This is known as global address validation. It helps ensure the packages are delivered to the right address and minimizes delivery delays caused by incorrect or incomplete addresses. This is especially important when orders come from customers in different countries, as address formats differ.

Real-Time Tracking Updates

This ensures customers are always up-to-date on the progress of their order, from the pickup to delivery at its destination. Shipping APIs in eCommerce allow customers to track their orders using tracking numbers provided by carriers and other affiliated shipping companies.

The tracking updates are provided in real-time, giving customers an accurate status of where their order is at any given moment and ensuring faster delivery times.

Rates & Transit Times Calculation

Shipping APIs enable businesses to accurately and quickly calculate shipment rates and transit times. The APIs can access a vast range of shipping options, allowing businesses to compare and select the best option for their needs.

Returns Management

Shipping APIs enable an efficient returns policy for eCommerce businesses. They allow customers to easily track packages while also allowing store owners to create efficient and automated returns procedures.

For example, if customers are dissatisfied with their product, they can fill out a simple form. The shipping API automatically generates return labels and notifies customers of their returns. This makes it easier for customers to return their items and more efficient for store owners to manage returns.
