Start exploring Lob APIs with Postman

At Lob, we’re dedicated to improving how developers learn and utilize our direct mail and address verification APIs. We are happy to announce the release of Lob’s Public Workspace on Postman.com. Postman is a collaborative API development platform, designed to simplify and streamline the process of creating APIs.

This workspace provides sophisticated tools for developers, while also enabling you to interact with our APIs without writing any code. This is a great way to learn about our endpoints, available parameters, sample payloads and how responses change based on various inputs.

In addition we’ve written documentation for using the workspace and a video walk-through — all so that developers have the best first-time experience with our APIs.

The backbone of this project is our OpenAPI 3.0 specification that we bundle and use to build our postman collection. You can find them on GitHub in the dist folder of our deployment branch.

We know there are many popular developer tools and platforms that you use daily to integrate with APIs. Drop us an email and tell us about them so we can work to add Lob support.
