title: Pull content from a remote WordPress install
body: <p>I need to create a wp widget that automatically pulls data from another wordpress install on a remote server.</p>
  
  <p>Basically, the source site is a review site where offers vary over time. My widget will pull certain offers and make sure they stay updated.</p>
  
  <p>Reviews on the source site are custom post types with custom meta fields that need to be fetched (price, offer, etc).</p>
  
  <p>Looking around I've seen different suggestions: query the remote db, fetch the feed (does it store custom meta fields?), use json (which I barely know what is, but I am willing to learn new stuff).</p>
  
  <p>What is the best method for my purpose and where can I find resources to help me achieving my goal?</p>
  
  <p>Thanks for your help!</p>
