Thanks @markd for your response. Yes I know my own tenants , the reason I need to know is because I am looking to integrate the tenant creation in our automation flow and part of that is to identify if the tenant exists if not skip the step and if it doesn’t create one and then keep in the same next cycle etc.
But by the looks of the URL and response it seems that Auth0 has no implementation of default errors and you always redirect user to same login page and never show any 404 signs so it makes the automation hard.
In my case I probably can go and list all my tenants and traverse and check each one against the input etc , which sort of makes it a bit lengthy process for a small use case.
