How to call the third-party express logistics order number to query api in Java, I believe many inexperienced people are at a loss about this. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Comparison of third Party Logistics Interface

There are two types of express query API: instant query and subscription query. Data is returned immediately upon request, subscription is to subscribe to the express order number to the API, and full data is returned if the logistics track is updated. At present, the commonly used are express bird, express 100, aggregate data, Aliyun logistics and so on.

Express bird instant API can query 3000 times, more than 3000 can be connected to the subscription interface, unified interface mode access, commonly used express delivery support query, as well as subscription API, online order API, electronic single API, the interface is free of charge, users are not required to add outside the chain, support 418 domestic and foreign express logistics query.

Express 100 can be queried 2000 times a day for free, with a charge of more than 2000 times, ranging from 0.06 to 0.1 yuan each time. If the number of queries is large, the fee can be reduced. Several common express delivery companies do not support the interface mode, but only support htmlAPI. Users are required to add external chains and support more than 300 domestic and foreign express logistics queries.

Because the company uses express bird products, so here finally chose the express bird logistics API.
