title: HTTP GET request for user's phone number in fulfillment editor
body: <p>We are setting up a chat bot through Dialogflow. A user will receive a weblink to the bot in a call or SMS sent through twilio. I'm wondering if it is possible for us to set up an HTTP get request to twilio in fulfillment so that we can set a context parameter to the user's phone number in the fulfillment inline editor in Dialogflow.</p>
  
  <p>I took a look at twilio's api docs but could only find information on HTTP requests regarding numbers purchased or available for purchase through twilio. </p>
  
  <p>So to clarify: in Dialogflow's fulfillment inline editor, we want to set a context parameter equal to the user's phone number that twilio called or sent the SMS to with a weblink to our chat bot.</p>
  
  <p>Thanks!</p>
