CRM Link custom CRM webhooks never being sent

I’m in the same situation as CRM Webhooks not being called, but a few years on. Fully up to date FreePBX 17 and all modules (in fact this is a brand new install from just a few days ago).

I’ve managed to subscribe a webhook for both inbound and outbound calls, but no webhooks are firing.

The documentation to create a webhook appears to be wrong. Sending a JSON request fails, however using form data seems to work:

POST https://REDACTED.NET:2443/admin/api/sangomacrm/rest/webhooks
Content-Type: application/x-www-form-urlencoded
Token: REDACTED

url = https://REDACTED.COM/REDACTED-webhooks/phone-call/ &
direction = both

I can view my webhook as successfully created:

However, no webhooks are sent. I’ve tried inbound and outbound calls.

The module is configured correctly, I believe:

I’m using the free trial of the CRM Link module with every intention of buying it if it works.

Please can you help as I really want to get this working and purchase this module. Thank you.

I can also confirm that these do appear in

fwconsole dbug

Both before and after the call, but the actual webhook HTTP request is not made.

Any help would be greatly appreciated. We’d love to pay for this module, but it just doesn’t seem to be working right now. Thank you.
