Alma as a web site lets us view, search, and edit our data in a variety of ways, but what if you want to do something slightly different? Fortunately, Ex Libris provides API access that allows you to add specialized functionality to your Alma workflows, or even access Alma's data through other web sites. In this presentation I will go over the basics of APIs, demonstrate how you can learn about and test them using the Ex Libris Developer Network, and show some examples of how they can be used to extend Alma's functionality.
