How to get unread message via rest api in Rocket.chat

Question

Hello I have used this https://docs.rocket.chat/api/rest-api/methods/channels/history for get unread message via rest API.

Example Call

1. (https://rcserver.rocket.chat/api/v1/im.history?roomId=ByehQjC44FwMeiLbX?&unreads=true)

2. (https://rcserver.rocket.chat/api/v1/im.history?roomId=ByehQjC44FwMeiLbX?&unreads=”+ true)

Code

HttpClient client = new HttpClient();
client.BaseAddress = new Uri(Constants.CONST_SITEURL);
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("X-Auth-Token", authToken);
client.DefaultRequestHeaders.Add("X-User-Id", userRcId);
HttpResponseMessage msgHistory = client.GetAsync(Constants.CONST_CHATHISTORY + userDetail.RC_RoomID + "&count=20&unreads=true").Result;
     if (msgHistory.IsSuccessStatusCode)
         {
           using (HttpContent content = msgHistory.Content)
                   {
                      var result = content.ReadAsStringAsync();
                      value = JObject.Parse(result.Result);
                    }
           directChatWindow = JsonConvert.DeserializeObject<DirectChatWindowBO>(value.ToString());
         }

I have try to above link and code but it will not give any unread property in result

Example Result

 {
  "_id": "7e6691fc-16sdfd3-ecbfsd8-317a-4076bb307e5dfsfd-4564",

As maintainer of the Rocket.Chat REST API, you actually brought to our attention a bug which has been present for a long time now (since we converted from coffeescript). I have submitted a pull request which fixes this issue, however to get the unreads to appear it does require changing how you use the im.history endpoint.

To get the unreads to appear you must also pass in the query parameter of oldest which is a string that can successfully be converted to a JavaScript Date object, see the Date.parse() documentation for details.

An example query url would look like:

http://localhost:3000/api/v1/channels.history?roomName=general&unreads=true&oldest=2017-01-01

Then a successful response which includes the unread information will look like the following:

{
    "messages": [
        {
            "_id": "pwiJmc7ZfEwebMEKP",
            "alias": "",
            "msg": "hello ;) ;)",
            "attachments": null,
            "parseUrls": true,
            "bot": null,
            "groupable": false,
            "ts": "2017-08-18T08:27:26.746Z",
            "u": {
                "_id": "HL2hEQSGask47a82K",
                "username": "graywolf336",
                "name": "graywolf336"
            },
            "rid": "GENERAL",
            "mentions": [],
            "channels": [],
            "_updatedAt": "2017-08-18T08:27:26.749Z"
        },
        {
            "_id": "YRch8iRsur7L6WF5B",
            "alias": "",
            "msg": "hello world",
            "attachments": null,
            "parseUrls": true,
            "bot": null,
            "groupable": false,
            "ts": "2017-08-18T08:21:50.072Z",
            "u": {
                "_id": "HL2hEQSGask47a82K",
                "username": "graywolf336",
                "name": "graywolf336"
            },
            "rid": "GENERAL",
            "mentions": [],
            "channels": [],
            "_updatedAt": "2017-08-18T08:21:50.073Z"
        }
    ],
    "firstUnread": {
        "_id": "3gJZbwLia6tuznPTk",
        "t": "uj",
        "rid": "GENERAL",
        "ts": "2017-07-31T22:53:20.579Z",
        "msg": "graywolf336",
        "u": {
            "_id": "HL2hEQSGask47a82K",
            "username": "graywolf336"
        },
        "groupable": false,
        "_updatedAt": "2017-07-31T22:53:20.579Z"
    },
    "unreadNotLoaded": 259,
    "success": true
}

As of August 8, 2017, this will not work until the pull request is merged. However after it is merged then this will work with development builds and once version 0.59 of Rocket.Chat is released then you can update your server and make usage of it.

Hopefully this helps, let me know if you have any questions and I will update my answer.
