Being developed with an API first mentality, FOLIO offers all aspects of functionality via API. This means that data can be created, read, updated and deleted (CRUD) using API; not just with FOLIO's UI. Working with FOLIO's API can be intimidating at first; however, freely available tools can make it a lot easier. In this session we will introduce you to FOLIO's API, some helpful tools, a few lessons learned from our mistakes, and the nuts and bolts behind some real-world examples. FOLIO's API can do things that the UI cannot; bring your wish list and we'll brainstorm some solutions.
