SharePoint 2013 & Office 365 APIs & Development Options for Accessing Data
SharePoint 2013’s APIs and Development Options for Accessing Data and Resources
SharePoint 2013’s APIs allow apps, as well as other elements, to connect and integrate with SharePoint’s core features.
EPC Group's development teams use APIs, as shown in the image below, provide apps their ability to view content or integrate with a workflow or even perform searches.
For example, if you were developing an app for a business intelligence initiative, SharePoint 2013’s APIs would allow your app to connect to SharePoint’s BCS and other elements in a secure manner to access specific data.
