When any user send chat message or reply any message we want to propagate this information to our custom application and perform some actions. Is there any way to trigger this event ?

Hello @Sahi Repswal

Thanks for reaching out!

You can use Change notifications to achieve this use-case. Change Notifications enable you to subscribe to changes (create, update, and delete) to messages in a channel or chat. Whenever, there will be new message in a Teams Channel or chat, notification will be triggered for that and based on the API response, you can automate your process further. Please follow this detailed documentation to know how change notifications works for MS teams resources.

Please note that "The maximum time a Teams subscription can last is 60 minutes; however, subscriptions can be renewed until the caller has permissions to access the resource".

Please do refer these:

The application should respond to this endpoint. Please make sure your app is running.
