Can't install webhook - CiviCRM 5.17.4
Created by: aiden-grau
Hi there,
The webhook was not automatically installed, when I try to manually create it using https://mysite.com/civicrm?page=CiviCRM&q=civicrm/sparkpost/callback I get "POST to webhook target URL failed with error code EPROTO"
Any ideas?
Thanks!
