Why do we need private key to connect to TronGrid API?

Dev Talks

I’m looking at the code to transfer tokens via TronGrid and it shows the below.

  const tronWeb = new TronWeb({
    fullHost: url,
    headers: { "TRON-PRO-API-KEY": AppKey },
    privateKey: privateKey,
  });

Is this the private key to my wallet?
