title: Localhost API for TD Ameritrade
body: <p>I was creating an API for TD Ameritrade (my first time creating or dealing with APIs) and I needed to put in my own call back URL. I know that callback URL is where the API sends information to and i heard that I can just use my localhost API. I scoured the internet and I dont know how that would work and I was wondering if i can just use <a href="http://localhost" rel="noreferrer">http://localhost</a>?</p>
  
  <p>Sorry if I seem like a noob because I am</p>
