API reference documentation

An add-in can use the Office JavaScript APIs to interact with objects in Office client applications.

• Application-specific APIs provide strongly-typed objects that can be used to interact with objects that are native to a specific Office application.
• Common APIs can be used to access features such as UI, dialogs, and client settings that are common across multiple Office applications.

You should use application-specific APIs whenever feasible, and use Common APIs only for scenarios that aren't supported by application-specific APIs. For more detailed information about these two API models, see Develop Office Add-ins.
