Overview of Viva Connections Extensibility

Developers can extend Microsoft Viva Connections for building engaging experiences with the widely adopted SharePoint Framework (SPFx). Viva Connections is your gateway to a modern employee experience where you can build and integrate apps that shape culture and foster connections to help employees thrive. With SPFx, you have multiple ways to extend – using the same out-of-the-box or custom SPFx web parts, SPFx extensions (for example, header and footer), and specific components for optimized mobile experiences.


See the Extend Microsoft Viva Connections learning path for a structured way to learn how you can extend Viva Connections, what tools you need, and how to get started.

Extensibility opportunities

Viva Connections is available as both a desktop via the installable Microsoft Teams client as well the mobile app. Both of these experiences, desktop & mobile, leverage the SPFx for all customizations and extensibility opportunities.

Viva Connections & Viva Home desktop experience

The Viva Connections & Viva Home desktop experience is implemented using SharePoint modern pages in SharePoint Online. Developers use the SPFx to customize modern pages in SharePoint using client-side web parts and extensions.

To learn more about customizing modern pages in SharePoint with SPFx, see Overview of SPFx client-side web parts & Overview of SPFx Extensions.

Viva Connections & Viva Home dashboard & mobile experience

The Viva Connections & Viva Home dashboard & mobile experience can be extended and customized using Adaptive Card Extensions (ACEs). Developers must use the SPFx create custom ACEs enabling customized experiences in Viva Connections dashboards and the Viva Connections mobile app.

To learn more about creating ACEs, see the following tutorial: Build your first SharePoint Adaptive Card Extension.


The SPFx v1.13 release introduced support for building solutions to customize and extend Microsoft Viva Connections. To learn more about the SPFx v1.13 release, including prerequisites & how to install it, see: SharePoint Framework v1.13 release notes.
