I am trying to setup a webhook for an Adobe IO event. It is failing on the validation step. For the asyncronous validation (https://www.adobe.io/apis/experienceplatform/events/docs.html#!adobedocs/adobeio-events/master/intro...), I am getting a URL that doesn't appear to be formed correctly. There is an example below where there are XXXXs in the url. Should the XXXXs be in the URL? The example in the documentation does not include them.
You can intercept the original validation URL if you own the webhook server (by simpy logging all requests). We purposefully obfuscate the validation URL in debug tracing tab for security reasons.
