Open Browser Window API requirement sets
Requirement sets are named groups of API members. Office Add-ins use requirement sets specified in the manifest or use a runtime check to determine whether an Office application supports APIs that an add-in needs. For more information, see Office versions and requirement sets.
The OpenBrowserWindow API set enables add-ins to open a browser to accomplish tasks that cannot always be done in the sandboxed webview control within the add-in itself; for example, downloading a PDF file when the webview control is provided by Microsoft Edge.
Office Add-ins run across multiple versions of Office. The following table lists the OpenBrowserWindow API requirement sets, the supported Office client applications, and the minimum builds or versions for those applications where applicable.
