Not able to get some custom value in the OnMembersAddedAsync or OnInstallationUpdateActivityAsync

[viveknuna]

We have developed the MS Teams app and We are publishing it using the policy and some users might download it manually from the teams store. We have developed this app for our many customers, so We want to know which customer user has installed the app in our code. I explored the OnMembersAddedAsync and OnInstallationUpdateActivityAsync, But I have not found any way to get our customer's ID in these events, because it may be different for different-2 users. and We would like to take some actions based on the given customerId.

Is there a way to get some custom value in the OnMembersAddedAsync or OnInstallationUpdateActivityAsync.

The above methods do not return customerId and there is no API to know details of installed a particular application.

You can get notified whenever the specified Teams app is installed, updated, or deleted from a team, groupChat, or a user's personal scope - https://learn.microsoft.com/en-us/graph/teams-changenotifications-appinstallation

@Meghana-MSFT so shall I call the mention graph API in my service startup?

@viveknuna - The above-mentioned Graph API will just notify you whenever the specified Teams app is installed, updated, or deleted. It does not return any customerId/userId etc. Currently there is no API to know details of users who installed a particular application.
