Required API permissions

The following Microsoft Graph API permissions are required by this app.

Some permissions may already be pre-approved by Microsoft, while others require manual approval by a user with the Global Administrator role after the app has been deployed. See our guide to approving API permissions for full instructions.

Scope Purpose Pre-approved by Microsoft
User.ReadBasic.All Read all users' basic profiles for audience targeting. ✅ Yes
GroupMember.Read.All Read group memberships for audience targeting. ✅ Yes


These permissions are delegated, apply organization-wide, and are essential for the app to function properly.

Data storage

The Welcome app stores data in a couple of locations within SharePoint, including the web part itself and in background SharePoint lists and libraries.

Web part

The Welcome app stores data such as manually created slide content directly within the web part configuration.

If the optional local weather feature is enabled, the app will require an API key from OpenWeather. This key must be entered in the web part’s property pane and is stored with the individual web part configuration.

Note: the free OpenWeather plan allows up to 1,000,000 API calls per month. If your organisation exceeds this limit, you may need to upgrade to a paid OpenWeather plan at your own cost.

SharePoint lists and libraries

The Welcome app provisions specific SharePoint lists and libraries during the initial data source creation setup to support its features and functionality. These include:

List/library title Relative URL Purpose
Welcome Web Part Weather /Lists/WMW_WMReplyWelcomeWebPartWeather A cache of the last updated weather information per location.
Welcome Web Part Errors  /Lists/WMW_WMReplyWelcomeWebPartErrors  Errors logged by Welcome when failing to obtain weather information.
Welcome Web Part - Custom Layouts /WMW_WMReplyWelcomeWebPartLayouts Storage of the custom layouts.

Recommended deployment scope

It is expected that the Welcome app is made available only on specific areas of your SharePoint tenant as necessary, e.g., a home site or landing site.

Therefore, it is recommended to select the Only enable this app option on deployment (see the Installation instructions page). This means the app is available for Site Owners to manually add to their site.
