Shipping API

Meeting client demand in today’s e-commerce environment entails being as efficient as possible and offering them a frictionless buying experience.

Having all of your shipping capabilities linked into your current tech stack allows your staff to receive information faster, allowing them to give the greatest customer experience possible.

To enjoy these tech capabilities, you need to choose the best shipping API. In this post, we’ll take a look at the 15 best shipping APIs for businesses. This post is packed with helpful insights so try to read it to the end.


Shipping API means Shipping Application Programming Interface. To fully understand what we mean by a shipping API, you must first understand that an API is essentially code that lets various web apps communicate and transfer data to one another.

Therefore, a shipping API is a code that you can integrate and customize in your present tech stack to communicate and access shipping capabilities across many apps. 

Shipping APIs enable organizations to incorporate all of the benefits of shipping software directly into their existing e-commerce technology stack. Programmers can help you integrate shipping services directly into your company processes or eCommerce website, providing you with greater flexibility using Shipping APIs

You can customize the Shipping API to particular company requirements and shipping carriers to boost fulfillment. It is a connection type that enables an eCommerce company to combine its online store, warehouse management system, or order management system with better shipping capabilities. This helps to streamline portions of shipping processes that are complex and time-consuming to arrange manually.

Assume that someone placed an order on your website. Instead of needing to use a separate application to compare shipping rates and print labels, you can get that functionality directly from your website thanks to the shipping API, which gathers data and functionality from one platform and displays the necessary information and capabilities for you in your current platform. 


1. Address Validation

Delivery failures or delays, as well as address changes, can have a negative influence on your brand’s reputation. Shipping APIs enable address validation, ensuring that packages are always delivered to the correct destination. 

2. Track Orders

Sometimes, a surge of orders can overburden e-commerce enterprises. With simple manual methods, you may pay for several shipping labels for the same order or lose track of a specific order as it moves through the fulfillment process on your 3PL platform.

Orders placed on your site are synced to the fulfillment center’s 3PL platform, which is also synced to the shipping program that generates the labels via a shipping API.

This means you can see and track the actual location of your orders throughout the fulfillment process without switching between too many programs. This not only assists inventory managers, but it may also assist your customer support team in answering any questions about the status of your customers’ orders.

Cart abandonment issues affect the majority of eCommerce firms today. A significant proportion of these purchasers who quit their carts during the checkout process do so due to a difficult or poor delivery experience, or simply because of the cost of shipping.

APIs can assist in tracking deliveries across many carriers and in informing clients of delivery status. Allowing your consumers to select the delivery alternatives that best meet their needs, as well as providing them with transparent tracking information, adds value to your company and creates loyalty.

5. Capabilities For Many Carriers

The ability to tailor shipping services and carriers to your individual needs will improve your company’s performance and productivity. When it comes to shipping carriers, there are several options accessible, each with its own set of advantages.
