Has anybody worked with glitch.com for webhooks in Creatio?

Hi All,

I am trying to add a webservice in Creatio that I have created on Glitch.com.
It´s a pretty simple command as Glitch is taking care of everything else: https://myproject.glitch.me/webhook

WHen I try it on a browser, terminal using CURL or Postman it all works like a charm, but when I try it on Creatio webservice I get 403 error while testing.

HTTPS/1.1 403 Forbidden
Connection: keep-alive

Any ideas or recommendations?
