Why am I receiving "message": "Forbidden - Your API key don't have privileges to data type"?

Question:

Why am I receiving "message": "Forbidden - Your API key don't have privileges to data type"?

Answer:

This occurs on WebSocket whenever a certain data type is being accessed that is not included in your current subscription tier.

Example:

{
"type": "hello",
"apikey": "73034021-SAMPLE-STARTUP-KEY",
"heartbeat": false,
"subscribe_data_type": ["quote"]
}

You will receive:

{
"message": "Forbidden - Your API key don't have privileges to data type 'quote'.",
"type": "error"
}

This is because the Quote data type is not available for the Startup Subscription via WebSocket.
