I have created a personal BOT and created a tabin the tab when the user click on the button that user automatically added to the groupchat
GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var conversationMember = new AadUserConversationMember
{
VisibleHistoryStartDateTime = DateTimeOffset.Parse("2019-04-18T23:51:43.255Z"),
Roles = new List<String>()
{
"owner"
},
AdditionalData = new Dictionary<string, object>()
{
{"user@odata.bind", "https://graph.microsoft.com/v1.0/users/8b081ef6-4792-4def-b2c9-c363a1bf41d5"}
}
};

await graphClient.Chats["{chat-id}"].Members
.Request()
.AddAsync(conversationMember);
Its throwing an error The initiator 8:orgid:e11885e0-aef7-41e7-be4b-a32c55b5b8e4 is not a member of the roster afbe6dc0-ab9b-49b7-8cfc-c9794834a6f8 in the generic thread 19:19496b7b2d12406694dabcf0edb24cee@thread.v2.isSelfJoining: True isSelfJoiningEnabled: False

Hi @Seelam, Bharathi (Cognizant)

The API supports both user context and application context, if you are using user context then you have to log in with the owner of the group chat and get token, then use that token to add new members, in user context only the group chat owner can add new members. If you are using application context then you can add new members directly.

Note that if your user is a guest, you must set roles to "guest" when adding him to the group chat.

Roles = new List<String>()  
{  
	"guest"  
}
