About Stamps APIs

Although a great deal of communication happens digitally, people still need to send physical letters and packages. Mailing a letter used to mean a trip down to the post office to purchase stamps. Today, applications allow individuals and businesses to handle postage online. When a business uses a website or app for its postal needs, the application connects with a stamp API.

What is a stamps API?

Figuring postage requires several pieces of information. For packages, postage is based on the weight of the item, the distance from the sender to the receiver, and the speed of delivery. An API is a data structure that allows an application to interact with a server. A postage API will supply information about the cost of postage and serve as a place to register transactions.

How does a stamps API work?

When someone has an item to send, the application they are using will request the API with data about the transaction. The API will return information on making address labels and costs. The user’s application will use this information to create the proper postage forms. When the transaction is final, the application posts the transaction on the API for tracking purposes.

What can developers expect from a stamps API?

Because these APIs are handling transactions, they have designated methods for common searches and commands. Developers should look for APIs with clear documentation to prevent errors. A comprehensive postage API will have resources for both domestic and international shipping.
