I am testing the API functionality. I have an API key but my testing account RezGo site is still off. Will API calls work? They don't at the moment but I am unsure why. If the "off" state of the site explains it then I would not need to hunt for other issues.
Yes it is related to the site being in the “off” state. More specifically, API calls cannot be accessed unless have added your credit card for billing purposes. Before turning the site on, you must add your billing info so this would allow you access to the API. However, if you are not ready to make your site live, you can simply add your billing information but not turn your site live. This will then allow you to test the API.
