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.

Schema

Validator for the webhook callflow data object

Key	Description	Type	Default	Required	Support Level
custom_data	JSON object of custom data included on the HTTP request	object()		false
http_verb	What HTTP verb to use when sending the request	string('post' | 'get')		false
retries	How many times to retry the request if the host isn't available	integer()		false
skip_module	When set to true this callflow action is skipped, advancing to the wildcard branch (if any)	boolean()		false
uri	The HTTP URI to send the request	string()		false

An example JSON action

{"module":"webhook"
 ,"data":{
     "uri":"http://my.ser.ver/path/to/webhook/destination"
     ,"http_verb":"post"
     ,"custom_data":{
         "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.
