title: Dialogflow retrieving data from Firebase Real time database
body: <p>Currently I'm working on a mobile app using Ionic and Angular2 with Realtime database service from firebase. I want to make a chatbot using Dialogflow to analyze the user request (i.e. I need a wheelchair) and then analyze the firebase db for any similar items stored, and if it exists, I need to show the item's name and the <em>uid</em> of the user who has added it into the database. </p>
  
  <p>Have seen some tutorials on Dialogflow with Cloud Firestore but I'm not sure whether this works with the Realtime DB and how it would work. </p>
  
  <p>Thanks in advance. </p>
