Developers, use our APIs to create applications, code libraries and more

Those about to code, we salute you. These are the stepping stones to build solutions using OCLC Web services. 

1 See OCLC Web services in action.

The API Explorer is a quick way to test requests and responses so you can get a feel for how our Web services work and start to think about what you can do with them.

2 Get authorized.

Authentication is the next step to putting our Web services through their paces. Request WSKeys for the services you want to use. 

3 Dig into the nitty gritty.

Our Web service documentation has all of the details you need to start building. Be sure to check out our GitHub Repository and user-created code libraries for handy shortcuts.

4 Show your work.

Share your project with the Developer Network community.

We are a worldwide library cooperative, owned, governed and sustained by members since 1967. Our public purpose is a statement of commitment to each other—that we will work together to improve access to the information held in libraries around the globe, and find ways to reduce costs for libraries through collaboration.
