I think I have this as well. Found it when I have opened Ratel and then under the Extra Settings tab. What would I use this API Key for? For sure not in a Webapp, right?
Yes I do but I can’t see how I would expose it and how I would be able to differentiate between my namespaces then - I only have one endpoint.
Not saying that this is the case but I’m not sure if this is the problem. The referer is https so I guess this should work. It also works if I don’t submit a custom header! I was assuming that a Shared Cluster is somehow similar to a dedicated instance, I just have access to one namespace. Furthermore, it would really surprise me if the built in GraphQL tab of the Cloud admin interface does not work as soon as a custom header is submitted. I’m guessing that it is not only me running a dedicated server.
