• The BigBlueButtonAPI.Core.BigBlueButtonAPIClient class provides functions to call the BigBlueButton APIs.

  • The public methods:

  API	Method
  create	public async Task<CreateMeetingResponse> CreateMeetingAsync(CreateMeetingRequest request)
  getDefaultConfigXML	public async Task<string> GetDefaultConfigXMLAsync(GetDefaultConfigXMLRequest request = null)
  setConfigXML	public async Task<SetConfigXMLResponse> SetConfigXMLAsync(SetConfigXMLRequest request)
  join	public string GetJoinMeetingUrl(JoinMeetingRequest request)
  end	public async Task<EndMeetingResponse> EndMeetingAsync(EndMeetingRequest request)
  isMeetingRunning	public async Task<IsMeetingRunningResponse> IsMeetingRunningAsync(IsMeetingRunningRequest request)
  getMeetings	public async Task<GetMeetingsResponse> GetMeetingsAsync(GetMeetingsRequest request = null)
  getMeetingInfo	public async Task<GetMeetingInfoResponse> GetMeetingInfoAsync(GetMeetingInfoRequest request)
  getRecordings	public async Task<GetRecordingsResponse> GetRecordingsAsync(GetRecordingsRequest request=null)
  publishRecordings	public async Task<PublishRecordingsResponse> PublishRecordingsAsync(PublishRecordingsRequest request)
  deleteRecordings	public async Task<DeleteRecordingsResponse> DeleteRecordingsAsync(DeleteRecordingsRequest request)
  updateRecordings	public async Task<UpdateRecordingsResponse> UpdateRecordingsAsync(UpdateRecordingsRequest request)
  getRecordingTextTracks	public async Task<GetRecordingTextTracksResponse> GetRecordingTextTracksAsync(GetRecordingTextTracksRequest request)
  putRecordingTextTrack	public async Task<PutRecordingTextTrackResponse> PutRecordingTextTrackAsync(PutRecordingTextTrackRequest request)

  Each method has similar style:

  Each method has a XXXRequest input parameter.

  Most of methods return Task<XXXResponse>, it contains the result data or error data: If the BigBlueButton API meets errors, the returncode of the response equals to Returncode.FAILED; the messageKey of the response is the error code; the message of the response is the error message.

  Only the GetDefaultConfigXMLAsync method and the GetJoinMeetingUrl method return string.

  • The constructor method:

  public BigBlueButtonAPIClient(BigBlueButtonAPISettings settings, HttpClient httpClient)

  The BigBlueButtonAPI.Core.BigBlueButtonAPISettings class contains the config data for the BigBlueButton API:

  The ServerAPIUrl property: The BigBlueButton server API endpoint (usually the server’s hostname followed by /bigbluebutton/api/, for example: http://yourserver.com/bigbluebutton/api/ ).

  The SharedSecret property: The shared secret code that is needed for the BigBlueButton server API. You can retrieve it using the command in your BigBlueButton server:
  $ bbb-conf --secret

• It makes some enhancements: meta, recording, etc.

• Code Sample
  Let's start a meeting (create a meeting and join it), client is the instance of BigBlueButtonAPIClient.

  [HttpPost]
  public async Task<ActionResult> Start(StartModel model)
  {
      if (!ModelState.IsValid) return View(model);
  
      //1. Create a meeting
      var responseCreateMeeting = await client.CreateMeetingAsync(new CreateMeetingRequest
      {
          name = "Test Meeting",
          meetingID = model.Id
      });
      //Check the response from the BigBlueButton server and return error if has error.
      if (responseCreateMeeting.returncode == Returncode.FAILED)
      {
          ModelState.AddModelError("", responseCreateMeeting.message);
          return View(model);
      }
  
      //2. Join the meeting as moderator
      var url = client.GetJoinMeetingUrl(new JoinMeetingRequest
      {
          meetingID = model.Id,
          fullName = model.Name,
          password = responseCreateMeeting.moderatorPW
      });
      return Redirect(url);
  }
