Fax Webhooks (Incoming & Outgoing)

• Incoming Fax Webhook Events will be POSTed to your URL whenever a fax is received. The body of the POST will be urlencoded (sorry, no JSON yet) with a download URL for you to retrieve the fax PDF. Fax PDFs are only kept for 30 days.
• Outgoing Fax Status Webhook Events will be POSTed to your URL whenever an outgoing fax changes status. Please review the Possible Responses in the above "Requesting Fax Status" section. The response will be in JSON.
  

Important! After setting up webhooks, you must hit the big red APPLY CHANGES button at the top. This is because a reload needs to occur in the phone system dial plan.
