Hi to all,

i want to send a teams 1-1 message chat.

the steps i did so far.

  1. login from https://login.microsoftonline.com/ with clint id/secret scope=> https://graph.microsoft.com/.default
  2. create 1-1 chat
    https://graph.microsoft.com/v1.0/chats
    { "chatType":"oneOnOne", "members":[ { "@odata.type":"#microsoft.graph.aadUserConversationMember", "roles":["owner"], "user@odata.bind": "https://graph.microsoft.com/v1.0/users('7........f')" }, { "@odata.type":"#microsoft.graph.aadUserConversationMember", "roles":["owner"], "user@odata.bind": "https://graph.microsoft.com/v1.0/users('9........3')" } ] }

From the response, i take the "id" and post as :
https://graph.microsoft.com/v1.0/chats/19:7c82222.....paces/messages

{
  "body": {
     "content": "Hello world"
  }
}

but i take an error about migration

{
    "error": {
        "code": "Unauthorized",
        "message": "Message POST is allowed in application-only context only for import purposes. Refer to https://docs.microsoft.com/microsoftteams/platform/graph-api/import-messages/import-external-messages-to-teams for more details.",
        "innerError": {
            "date": "2024-03-14T13:27:32",
            "request-id": "efee9ffb-28a6-4ffe-a398-57adec529133",
            "client-request-id": "efee9ffb-28a6-4ffe-a398-57adec529133"
        }
    }
}
