So I've used the Web API, but was unaware of the TCP API until this week. I'm attempting to use it, but am confused!
What are you sending the commands with? A browser? script code? In a browser, all I get is a search response. It's obvious I am misinterpreting the information provided. I had been using Autohotkey to send commands via web commands to vMix, but if the TCP API is more efficient, its obviously the way to go. Just need a little push in the right direction to get started.
Can anyone give me a push?

First you need to connect to vMix using TCP protocol.
Then transmit the command in UTF-8 format.
Also check the answer from the sent command success or error.

TCP connection example
client.Connect("127.0.0.1", 8099);
NetworkStream stream = client.GetStream();
Byte[] readingData = new Byte[1024];
String responseData = String.Empty;
StringBuilder completeMessage = new StringBuilder();
int numberOfBytesRead = 0;
do
{
numberOfBytesRead = stream.Read(readingData, 0, readingData.Length);
completeMessage.AppendFormat("Answer: {0}", Encoding.UTF8.GetString(readingData, 0, numberOfBytesRead));
}
while (stream.DataAvailable);
responseData = completeMessage.ToString();
textBox1.Text = responseData;
Example of TCP transfer vMix command
textBox1.Text = "";
Byte[] data = Encoding.UTF8.GetBytes("FUNCTION OverlayInput1Out\r\n");
NetworkStream stream = client.GetStream();
stream.Write(data, 0, data.Length);
Byte[] readingData = new Byte[1024];
String responseData = String.Empty;
StringBuilder completeMessage = new StringBuilder();
int numberOfBytesRead = 0;
do
{
numberOfBytesRead = stream.Read(readingData, 0, readingData.Length);
completeMessage.AppendFormat("Answer: {0}", Encoding.UTF8.GetString(readingData, 0, numberOfBytesRead));
}
while (stream.DataAvailable);
responseData = completeMessage.ToString();
textBox1.Text = responseData;
