  • Can you include the output of https://developers.google.com/apis-explorer/#p/webmasters/v3/webmasters.sites.list and a screenshot of https://console.cloud.google.com/apis/credentials/domainverification to help see if there is a problem with the domain verification? – David Sep 25 '18 at 20:55

I know I'm late to the party but anyway I'll let here an answer in case someone is interested.

Object Change Notifications are a legacy feature that allowed to add a watcher to a Storage Bucket pointing to a HTTPS url that would receive information about the object changes. The information about these notifications could be found here.

One of the requirements to use this feature is that the URI ob the webhook needs to be verified for ownership as explained here. From the error message it seems that was actually the reason.

Nowadays the preferable approach to obtain notifications regarding object changes would be to enable PubSub notifications which are easier to set up and more scalable and cost-effective. More information in the docs
