OK - there's nothing else I can test.
Trying to trigger a webhook in Freshdesk via observer.
- I can use the Freshdesk API without problem via cURL. Was able to update ticket etc, to test my calls without issue.
- I can trigger a webhook to a DIFFERENT platform via my observer rule, and the payload I set gets passed over just fine.
- I've tried BOTH the new and old API
- I've tried authentication via username/password AND via API key

Any insight appreciated. Essentialy, webhooks seem to work fine if they're sending to a non-Freshdesk URL. And API calls to the Freshdesk URL work fine from command line. BUT - webhooks triggered via Observer to the Freshdesk API do not work.
I'm wondering if it's something to do with the authentication, because this is the only piece I can't test. I can't see the error messages it's throwing, so I have no idea how else to test.
This is one of the half dozen permutations I tried:
