 * Yeah, meta data is a little different. You must explicitly expose to the API 
   the meta data you want to get or manipulate. See [https://developer.wordpress.org/rest-api/extending-the-rest-api/modifying-responses/](https://developer.wordpress.org/rest-api/extending-the-rest-api/modifying-responses/)
 * The reason for this is some installations can have a ton of meta data which, 
   if all was arbitrarily sent with post requests, could significantly increase 
   the data transmitted, slowing down the entire process. By requiring us to expose
   meta data we’re interested in to the API, the amount of data sent for any given
   request will be much more efficient.
