Sangoma CRM module - POST API call returns page not found

I am testing Sangoma CRM commercial module on my FreePBX v 16. The module is licensed and everything updated. My intended setup is to send a custom webhook to a URL of choice, as my own CRM is unsupported so I’ll build out everything from there myself.

Based on the documentation I:

  • Set Settings > CRM Setup to RestAPI
  • CRM API Settings seem correct: I have a valid base URL ending with :2443/admin/api/sangomacrm/rest , API is Enapled. API Token is given and Send Webhooks set as @Start and End.

From there I use postman to>

  • POST to the URL above
  • Authorization API Key | Key “Token” | Value | Add to Header
  • Body:
"url":"<MY WEBHOOK URL>",

When I send I receive back a page not found HTML message back>


    <title>Page Not Found</title>
        body {
            margin: 0;
            padding: 30px;
            font: 12px/1.5 Helvetica, Arial, Verdana, sans-serif;

        h1 {
            margin: 0;
            font-size: 48px;
            font-weight: normal;
            line-height: 48px;

        strong {
            display: inline-block;
            width: 65px;

I opened a ticket with Sangoma, but I receive an answer every 2-3 days an nothing has been solved so far. I was wondering if you had any pointer or major steps I skipped to make this work so I could try myself.
