Add custom data to users using open extensions
This article walks you through an example to demonstrate how to use open extensions.
Imagine you're building an application that is available on lots of different client platforms, such as desktop and mobile. You want to let users configure their UI experience so it’s consistent no matter which device they use to sign in to your app. This is a common requirement for most apps.
For this scenario, this article will show you how to:
- Add an open extension representing some roaming profile information about the user.
- Query the user and return the roaming profile.
- Change the user's roaming profile information (the open extension value).
- Delete the user's roaming profile information.
Note
This topic shows you how to add, read, update and delete open extensions on a user resource. Open extensions are also supported and can be managed for other resource types.
1. Add roaming profile information
The user signs in to the app and configures the look and feel of the app. These app settings should roam so that the user gets the same experience on whatever device they sign in to the app from. Here we'll see how to add the roaming profile information to a user resource.
Request
POST https://graph.microsoft.com/v1.0/me/extensions
Content-type: application/json
{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"com.contoso.roamingSettings",
"theme":"dark",
"color":"purple",
"lang":"Japanese"
}
Response
HTTP/1.1 201 Created
Content-Type: application/json
{
"@odata.type": "#microsoft.graph.openTypeExtension",
"extensionName": "com.contoso.roamingSettings",
"id": "com.contoso.roamingSettings",
"theme": "dark",
"color": "purple",
"lang": "Japanese"
}
2. Retrieve roaming profile information
When the user signs in to the app from another device, the app can retrieve the user's profile details as well as their roaming settings. This can be done by getting the user's resource and expanding the extension navigation property.
Request
GET https://graph.microsoft.com/v1.0/me?$select=id,displayName,mail,mobilePhone&$expand=extensions
Response
HTTP/1.1 200 OK
Content-Type: application/json
{
"id": "84b80893-8749-40a3-97b7-68513b600544",
"displayName": "John Smith",
"mail": "john@contoso.com",
"mobilePhone": "1-555-6589",
"extensions": [
{
"@odata.type": "#microsoft.graph.openTypeExtension",
"extensionName": "com.contoso.roamingSettings",
"id": "com.contoso.roamingSettings",
"theme": "dark",
"color": "purple",
"lang": "Japanese"
}
]
}
Note
If you have multiple extensions, you can filter on the id to get the extension that you're interested in.
3. Change roaming profile information
The user can choose to change their roaming profile information. This update can be done with a PATCH on the open extension value.
Request
PATCH https://graph.microsoft.com/v1.0/me/extensions/com.contoso.roamingSettings
Content-type: application/json
{
"theme":"light",
"color":"yellow",
"lang":"Swahili"
}
Response
HTTP/1.1 204 No content
4. Delete a user's roaming profile
The user decides that they don't want a roaming profile anymore, so they delete it. This can be done with a DELETE request on the open extension value.
Request
DELETE https://graph.microsoft.com/v1.0/me/extensions/com.contoso.roamingSettings
Response
HTTP/1.1 204 No content
