body: <p>What is best way to secure API calls from AngularJS(Mobile application) / HTML pages to a Laravel PHP backend?</p>
  
  <p>To be clear, I'm NOT talking about user login authentication.</p>
  
  <p>I'm planning an API based application. I would like to read the JSON data from my API into an page using AngularJS, before any user is asked to sign up or log in.</p>
  
  <p>I need to ensure that only my client front-end can access this data. Is there an existing system to send a token or utilise my secret key, to ensure that only my front-end can access my API? I would also like to be able to revoke access from a specific client or tenant.</p>
  
  <p>What are security options for this set up? I'm thinking along the lines of JWT, CORS etc... This is my first attempt at such an application, so please forgive my ignorance! How to securely access API from Mobile application </p>
