If you’re at our Free plan and using your own Google API key, you might sometimes cope with problems like these.
“Why can’t I save my API key?” This may be because your API settings are wrong, for example: your config is missing in Google Console, no billing setup, set restrict to all websites, etc.

=> If the system gives an error when you enter the API key, please capture your API setup in Google Console and send it to us via firstname.lastname@example.org. We’ll respond to your issues as soon as possible and our technical team will help you fix them if there are any.
Or, you can upgrade to paid plans (Basic, Advanced and Platinum) and use our built-in API key for a smoother operation.
