In the modern world of e-commerce, giving customers what they want involves minimizing any potential hassles they could encounter. Your team will be able to deliver the greatest possible customer service if all of your shipping capabilities are integrated into your present tech stack.

We’ll break down all you need to know about shipping APIs to better illustrate the significance of this solution and how you can utilize them to positively affect your ecommerce company.

What Does It Mean To Have A Shipping API?

Shipping Application Programming Interfaces (APIs) are a crucial component of every well-oiled shipping operation. When used correctly, shipping API integration may greatly improve the efficiency and effectiveness of any e-commerce shipping.

The abbreviation “API” refers to the interface via which particular programs for various applications may be set up. Any application or system’s API may be thought of as a database of information about that application or system. The data is then used to instruct the API to do the desired actions.

With the YouTube API, for instance, other websites may embed YouTube videos with the same user experience as the famous video-sharing platform. Shipping API is also used by carriers and delivery management systems to complete a variety of shipping-related operations.

Why Shipping APIs Are Important In eCommerce

There is a growing tendency toward purchasing online, which highlights the necessity of shipping APIs for e-commerce. A recent poll found that 68 percent of online buyers said that faster shipment would encourage them to make a purchase.

When there are too many operations that must be performed manually, it becomes next to impossible to satisfy such high standards for customer satisfaction. With the correct API, shipping APIs may cut down on time spent transferring data between applications, the likelihood of human mistakes, and shipping expenses.

1. Order Tracking

For online retailers, the Christmas season is a very busy time of year, and the resulting influx of orders may be difficult to handle. Due to the inherent inefficiency of manual procedures, it is easy to waste money by printing several shipping labels for the same order or to lose track of a specific order on your 3PL platform.

When customers make orders on your website, the 3PL platform in the fulfillment center receives the data and updates the shipping software used to create labels. As a result, you won’t have to go back and forth between different programs to see and keep tabs on the progress of your orders throughout the fulfillment process.

This aids inventory managers and may also aid your customer service department in responding to inquiries about the delivery of customers’ purchases.

2. Improve Shipping Efficiency

Improved productivity in the shipping department is one of the main draws of a shipping API. Take the case of entrusting your shipment fulfillment to a third-party logistics provider like Cmarix.

With the use of a shipping API, the company may tell its staff about the products that need to be packaged at its fulfillment centers, the most appropriate shipping carrier, and any other relevant details about each shipment. In turn, this means fewer questions and less back-and-forth on specific orders, which expedites processing and shipment.

3. Guaranteed Delivery Safety

No company, even in an ideal setting, can avoid the possibility of supply chain management problems. If shipping APIs are implemented, however, you may rest easy knowing that hackers won’t be able to disrupt your supply chain.

You can trust APIs to keep your shipping information safe and ensure its smooth movement to your other fulfillment platforms and business partners.

You may be able to reduce your shipping costs by using a more cost-effective shipping API. To provide just one example, if you add Shippo to your present technology stack, you may save money on shipping labels from the best carriers in the country thanks to savings that were already negotiated for you.

Depending on the label, discounts may reach 90% for USPS and 86% for UPS international shipments. All of these price reductions will add up to a larger saving on each purchase you place. Shippo’s API may be automated to always choose the lowest pricing for certain orders thanks to its integration with numerous carriers.

The best carrier to employ depends on what you’re shipping, where it’s going, and how long the consumer will wait.

Using a shipping API that supports various carriers lets you compare shipping prices in one place.
