Webhook

Webhook

Send a custom webhook to your web server during the callflow.

The Webhook Callflow Action

Webhooks can be triggered from a callflow without needing them to be predefined by an API call. They are useful in tracking the state of a caller in a phone tree, triggering actions on the receiver’s end, or whatever imagination can come up with.

         "some_id":"123abc"
         ,"app":"my_cool_app"
     }
 }
}

Using the webhook action in a callflow

To receive a webhook anytime the main company number goes to voicemail instead of being answered, for instance:

{"numbers":["+10005559999"]
 ,"flow":{
     "module":"device"
     ,"data":{"id":"front_desk_device_id"}
     ,"children":{
         "_":{
             "module":"webhook"
             ,"data":{
                 "uri":"http://my.ser.ver/frontdesk/missed_call"
             }
             ,"children":{
                 "_":{
                     "module":"voicemail"
                     ,"data":{"id":"front_desk_voicemail_box_id"}
                 }
             }
         }
     }
 }
}

Now your web server will receive a webhook payload anytime the caller is sent to voicemail instead of talking to the front desk.
