I'm working on my own ChatBot for YouTube in Winforms and C#. It already works on Twitch and I'm trying to replicate the functionality for Youtube using the C# API. I can download the Chat Messages no problem, but creating a chat message is causing me a headache as I'm getting a 403, Insufficient Permission error. The full error message is
Google.Apis.Requests.RequestError
Insufficient Permission [403]
Errors [
Message[Insufficient Permission] Location[ - ] Reason[insufficientPermissions] Domain[global]
]
After some searching I've tried most things that I can find and have still come up empty as to what exactly is causing this. I get it's a permission issue and I obviously need to set something but I can't figure out what. My code is below and definitely works for reading data... but i don't know why it won't work for writing.
public class YouTubeDataWrapper
{
private YouTubeService youTubeService;
private string liveChatId;
private bool updatingChat;
private int prevResultCount;
public List<YouTubeMessage> Messages { get; private set; }
public bool Connected { get; private set; }
public bool ChatUpdated { get; set; }
//public Authorisation Authorisation { get; set; }
//public AccessToken AccessToken { get; set; }
public YouTubeDataWrapper()
{
this.Messages = new List<YouTubeMessage>();
}
public async void Connect()
{
Stream stream = new FileStream("client_secrets.json", FileMode.Open);
UserCredential credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(GoogleClientSecrets.Load(stream).Secrets, new[] { YouTubeService.Scope.YoutubeForceSsl }, "user", CancellationToken.None, new FileDataStore(this.GetType().ToString()));
stream.Close();
stream.Dispose();
this.youTubeService = new YouTubeService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = this.GetType().ToString()
});
var res = this.youTubeService.LiveBroadcasts.List("id,snippet,contentDetails,status");
res.BroadcastType = LiveBroadcastsResource.ListRequest.BroadcastTypeEnum.Persistent;
res.Mine = true;
//res.BroadcastStatus = LiveBroadcastsResource.ListRequest.BroadcastStatusEnum.Active;
var resListResponse = await res.ExecuteAsync();
IEnumerator<LiveBroadcast> ie = resListResponse.Items.GetEnumerator();
while (ie.MoveNext() && string.IsNullOrEmpty(this.liveChatId))
{
LiveBroadcast livebroadcast = ie.Current;
string id = livebroadcast.Snippet.LiveChatId;
if (!string.IsNullOrEmpty(id))
{
this.liveChatId = id;
this.Connected = true;
}
bool? def = livebroadcast.Snippet.IsDefaultBroadcast;
string title = livebroadcast.Snippet.Title;
LiveBroadcastStatus status = livebroadcast.Status;
}
}
public async void UpdateChat()
{
if (!this.updatingChat)
{
if (!string.IsNullOrEmpty(this.liveChatId) && this.Connected)
{
this.updatingChat = true;
var livechat = this.youTubeService.LiveChatMessages.List(this.liveChatId, "id,snippet,authorDetails");
var livechatResponse = await livechat.ExecuteAsync();
PageInfo pageInfo = livechatResponse.PageInfo;
this.ChatUpdated = false;
if (pageInfo.TotalResults.HasValue)
{
if (!this.prevResultCount.Equals(pageInfo.TotalResults.Value))
{
this.prevResultCount = pageInfo.TotalResults.Value;
this.ChatUpdated = true;
}
}
if (this.ChatUpdated)
{
this.Messages = new List<YouTubeMessage>();
foreach (var livemessage in livechatResponse.Items)
{
string id = livemessage.Id;
string displayName = livemessage.AuthorDetails.DisplayName;
string message = livemessage.Snippet.DisplayMessage;
YouTubeMessage msg = new YouTubeMessage(id, displayName, message);
string line = string.Format("{0}: {1}", displayName, message);
if (!this.Messages.Contains(msg))
{
this.Messages.Add(msg);
}
}
}
this.updatingChat = false;
}
}
}
public async void SendMessage(string message)
{
LiveChatMessage liveMessage = new LiveChatMessage();
liveMessage.Snippet = new LiveChatMessageSnippet() { LiveChatId = this.liveChatId, Type = "textMessageEvent", TextMessageDetails = new LiveChatTextMessageDetails() { MessageText = message } };
var insert = this.youTubeService.LiveChatMessages.Insert(liveMessage, "snippet");
var response = await insert.ExecuteAsync();
if (response != null)
{
}
}
}
The main code in question is the Send Message method. I've tried changing the Scope of the UserCredentials to everything I can try to no avail. Any ideas?
