Shipping API: What to Consider Before Integration

Modern supply chains consist of many connecting points. Today it is not just manufacturer -> retailer -> buyer. Companies work with multiple suppliers and customers, take orders 24/7, and ship goods seven days a week. For efficient operation, they need to minimize downtime. However, tracking every step of a product journey on third-party resources is time-consuming. Additionally, the diversity of interfaces prevents time-efficient logistics.

Third-party services integration provides businesses with new opportunities. It allows companies to synchronize sending and receiving times and to control all shipping channels from one place. If you want to implement a robust logistics mechanism in your app, you need to connect to shipping services via shipping or tracking API. Below we’ll explain what benefits you will get and what challenges you may face during shipping API integrations.

What supply chain challenges does 2022 bring to retail and e-commerce?

2022 will be driven by the continuous growth of Internet users and mobile app revenues. To stay afloat, companies need to plan supply chain and logistics according to current realities. Here’s a breakdown of challenges they will face:

Higher customer expectations

This will put significant pressure on industries, making them look for new ways to refine customer service. Healthcare, e-commerce, automotive, and other companies will strive to enhance logistics, personalize orders, and shorten delivery time. Given the vast geography of suppliers and customers, companies will need to partner with more shipping service providers to reduce delivery time. Additionally, they will have to develop multi-carrier tracking software to track cargo paths on their side.

Growing customer expectations in different industries

Stronger competition

Retail m-commerce sales share grows every year. The pandemic has created new shopping norms by making online purchases more familiar, convenient, and widespread. Even when Covid19 is left far behind, new habits will stay in our everyday life. People will prefer to buy online, which means more sellers will enter the online market. To hold the position, e-commerce companies will need to look for new shipping integrations to ensure fast and uninterrupted deliveries.

The rise of quick commerce

The fast pace of life prevents people from building long-term plans. Often, purchasing decisions are made on the spur of the moment, and users expect the order to be delivered right away. Today, one or two days spent on shipping is too long. When it comes to grocery items, users expect them to be delivered within an hour or less. In this regard, shipping API is used for integration with services that partner with local short-distance carriers by bicycle, scooter, or on foot.

The quick commerce ordering and delivery cycle

Driver shortage

In 2021, the driver shortage peaked at 80,000 people. Such a personnel crisis has affected many businesses, forcing them to look for new ways to plan and optimize delivery routes. Shipping API development played a vital role in this process. With its help, companies create custom shipping platforms that connect with multiple providers and help customize delivery on their side.

Omnichannel sales

Today, sellers and buyers interact through various channels: online stores, social media accounts, brick-and-mortar shops, and more. The fragmentation of selling spots and warehouses creates new logistics challenges. A shipping engine that joins all selling channels and updates product stock in real-time solves this problem. Using tracking API, a shipping engine connects with different postal services and allows tracking delivery from one place.

Benefits of shipping API integration

Freight and carrier API gives access to various delivery providers. It streamlines the functionality of different apps: e-commerce stores, online pharmacies, automotive constructors, gifting services, warehouses, and more. Shipping API opens new opportunities for businesses. Here is how companies benefit from using it:

Lower shipping rates

By integrating various shipping services into your application, you can compare their prices on your platform. It allows you to choose the optimal rate after considering both distance and speed.

Less checkout abandonment

Many customers interrupt checkout when they cannot find a suitable shipping method. However, with multiple shipping options at hand, they are more likely to find an acceptable alternative and then continue shopping.

Real-time tracking

Package tracking API allows customers to trace a parcel and see up-to-date information about the status of their order. Also, it reduces the load on the contact center by eliminating calls regarding the parcel location.

Better planning

Logistics API integration allows you to track shipping in real-time. This is especially important for manufacturing companies that depend on many suppliers and must plan their product assembly in advance.

Growing business prospects

Whether you run an e-commerce business or own a carrier company, shipping API opens new business opportunities and enhances UX. It optimizes supply chain planning, reduces delivery costs, and minimizes downtime during transportation.
