Cvent has two ways of adding attendees either by adding them as an invite or registering them. Our account is set up to use the invite route.
With how our cvent account is set up I’m unable to use the pre-built “add Attendee” step, which uses the register route, so I’ve added an API request step. Unfortunately when I try to use the URL from their developer portal (https://api-platform-eur.cvent.com/ea/attendees ) I get an error “Domain did not match expected domain filter `io.cvent.com`” which I think refers to a previous version of the API. When I amend the request to use the equivalent io.cvent.com URL I get a 403 error.
Is there a way round this other than dropping back to pure webhooks?
