With many years’ experience of video conferencing development behind us, we are happy to share TrueConf’s best solutions with our users and customers. Many of TrueConf’s functions are available in the form of various SDKs and APIs. Bring to life your most daring video conferencing and collaboration ideas with the help of our development kits!

SDK for Windows

This library is designed for adding video conferencing into any software for Windows. It is based on ActiveX technology and can be used in any development frameworks for this operating system, including IDE Microsoft Visual Studio and Embarcadero Delphi, as well as JavaScript applications for Internet Explorer 8+ (incredible as it may seem!).
All applications based on this SDK can be integrated into your video conferencing infrastructure. TrueConf Server software or private cloud containing several TrueConf Servers can be used as video conferencing server. The number of users supported by your infrastructure is not limited.

Call users with user ID based in C#

private void buttonCall_Click(object sender, EventArgs e)
{
	if (textBoxTrueConfIdForCall.Text != "" && isCanCall)
	{
		axTrueConfCallX1.call(textBoxTrueConfIdForCall.Text);
		textBoxTrueConfIdForCall.Text = "";
    }
}

private void buttonEndCall_Click(object sender, EventArgs e)
{
	if (!isCanCall)
	{
		axTrueConfCallX1.hangUp();
		isCanCall = true;
	}
}

private void buttonCall_Click(object sender, EventArgs e)

{

if (textBoxTrueConfIdForCall.Text != "" && isCanCall)

{

axTrueConfCallX1.call(textBoxTrueConfIdForCall.Text);

textBoxTrueConfIdForCall.Text = "";

}

private void buttonEndCall_Click(object sender, EventArgs e)

{

if (!isCanCall)

{

axTrueConfCallX1.hangUp();

isCanCall = true;

}

Accept incoming call based in Pascal (Delphi)

procedure TForm1.TrueConfCallX1XAfterStart(Sender: TObject);
begin
  TrueConfCallX1.XSetCameraByIndex(0);
  TrueConfCallX1.connectToServer('127.0.0.1');
end;

procedure TForm1.TrueConfCallX1ServerConnected(ASender: TObject; const eventDetails: WideString);
begin
   TrueConfCallX1.login('user', 'password');
end;

procedure TForm1.TrueConfCallX1InviteReceived(ASender: TObject; const eventDetails: WideString);
begin
	Application.Restore;
	TrueConfCallX1.accept;
end;

procedure TForm1.TrueConfCallX1XAfterStart(Sender: TObject);

begin

TrueConfCallX1.XSetCameraByIndex(0);

TrueConfCallX1.connectToServer('127.0.0.1');

end;

procedure TForm1.TrueConfCallX1ServerConnected(ASender: TObject; const eventDetails: WideString);

begin

TrueConfCallX1.login('user', 'password');

end;

procedure TForm1.TrueConfCallX1InviteReceived(ASender: TObject; const eventDetails: WideString);
