Azure Communication Services - Chat events

This article provides the properties and schema for communication services chat events. For an introduction to event schemas, see Azure Event Grid event schema. These events are emitted for Azure Communication Services chats and Teams meeting chats.

Azure Communication Services emits chat events only when Azure Communication Services users are part of the meeting. Once all Azure Communication Services users leave the meeting, the communication services resource does not emit chat events.

Event types

Azure Communication Services emits chat events on two different levels: User-level and Thread-level. User-level events are specific to each user in the chat thread and are delivered once per user, excluding the event sender. Thread-level events pertain to the entire chat thread and are delivered once per thread. For instance, when a message is received in a thread with 10 users, there will be one thread-level event and 9 user-level events, one for each user, except for the sender.

Azure Communication Services emits the following chat event types:

Event type Level Description
Microsoft.Communication.ChatMessageReceived User Published when a message is received in a chat thread with a specific user
Microsoft.Communication.ChatMessageEdited User Published when a message is edited in a chat thread with a specific user
Microsoft.Communication.ChatMessageDeleted User Published when a message is deleted in a chat thread with a specific user

Event responses

When an event is triggered, the Event Grid service sends data about that event to subscribing endpoints.

This section contains an example of what that data would look like for each event.
