Anyone involved in the e-commerce industry nowadays knows all too well about the importance of complex serviceability. Users are willing to have a smooth and painless experience, starting from the checkout to the product’s delivery. Indeed, with the vast number of players in the market, including corporate giants and small enterprises, shipping is one of the most critical aspects determining business success.

In today’s tech-savvy reality, manual work seems like an outdated option. Thus, e-commerce companies need a robust solution to stay afloat in such a competitive environment. And the answer is pretty short — shipping APIs! Let’s delve into the discussion about their concept, functions, and benefits. Moreover, we will overview the top 5 shipping API integrations and look at the tips on choosing the right one!

What is a Shipping API?

For starters, an application programming interface — or simply an API — is a programming code that enables the proper interaction between multiple software services. With the help of APIs, completely distinct channels can share required information with one another, automatically collect and transfer data, analyze it, and even send messages! Moreover, the application programming interface plays a pivotal role in the functionality of various platforms.

Therefore, a shipping or a courier API is a solution specifically designed for the e-commerce industry that streamlines and optimizes the overall performance of the software applications. Thanks to the usage of strategic programming codes, logistics API is great in helping manage and track shipments. The most significant value of this integration is that e-commerce businesses can connect their management systems with improved shipping capabilities and operations that are a nightmare to perform manually. Delivery APIs are fully automated and consequently both cost and time efficient.

In other words, shipping APIs come in handy if you want to incorporate shipping functionalities into business operations and effectively coordinate them. They collect information from different platforms and display everything in one place. This way, you have to forget about stressing out and running from one application to another, manually gathering all the data. Long story short, an API for shipping is one of the most beneficial ways to gain fulfillment and enhance the communication between a business and its customers.

Key Functions of Shipping APIs

As we know, the shipping API for e-commerce is an incredible way to enhance all internal processes, making the workflow more efficient and less complicated. And the ability to have all essential features in one place rather than multiple freight management systems is the most vivid proof! In fact, the functionality of shipping APIs changes depending on the specialization of delivery services.

For instance, some companies might need profound third-party package tracking, while others need functionality for international shipping. Nevertheless, let’s review some key functions of basic shipping APIs that can help companies improve their shipping software.

Shipment tracking

Certainly, customers want to be updated with real-time information about products. That might include an estimated delivery time of their purchase, whether sold-out goods are back in stock or the launching of brand-new ones. Shipping APIs can incorporate all that information with the help of different channels — email, text message, website or a mobile application. Hence, users will instantly receive notifications via the preferred option with every status update or change. This function allows the company to improve their customer service and inventory management from behind the scenes!

Label creation

One of the primary and basic functions of shipping API integrations is the ability to create shipping labels. Basically, right after customers make purchases, a shipping API sends all related information to the shipping carrier. This way, the label data will be returned with an URL to download the auto-generated label, print it or save it for the future. And just like that the order is ready to start its shipping journey! With the help of the API and such an easy label generation, the shipping tracking is no longer a burden.

Address validation

The most common mistake that can be made while placing an order is putting a typo in the customer’s address. Since we are all humans, such tiny errors never seem inevitable. Nevertheless, fixing such issues might actually cost the company a fortune: printing new shipping labels – check, managing the return process — check, losing revenue from customers because of a poor experience they had — check.

However, shipping APIs can help you save your tears for another day and prevent any unfortunate events! The website, delivery app or any other platform won’t let the user move further if they haven’t verified their shipping address. In case an API identifies it as invalid, the customer will be immediately notified by the platform.

Benefits of API for Shipping

The logistics industry apparently benefits from API shipping integration, which can not but rejoice. No supply chain partners (shippers, carriers, brokers and customers) can get lost in the constant communication process! API shipping integration manages to ease the work by automating many functions. That includes transferring information, managing and tracking shipments and raising customer service to a higher level. To specify all the significant advantages, we will discuss this topic right away! Here are the benefits which the integration of top shipment tracking APIs brings to the logistics businesses:

Reduced shipping cost

Thanks to the shipping APIs, e-commerce businesses charge their customers for delivery services at a much smaller fee than it would be without it.
