title: Creating a custom API in ASP.NET
body: <p>I'm creating a site, and I need to create a basic API.  Unfortunately I have no idea where to start.</p>
  
  <p>My site will basically keep track of errors from other users' ASP.NET sites, and they can come to my site to filter through them, search through them, comment, resolve, etc.  I need to create an API, where the user can insert a few lines of code in the Application_Error event in the global.asax file, and it will pass an exception object to my site to be stored.</p>
  
  <p>It's the communicating between their site and my site that I don't understand and have no experience with.</p>
  
  <p>Does anyone know of a good tutorial for creating a basic API like this?</p>
