Sorry, I am not very familiar with this.
Thank you for your quick reply.
Do I add a ‘key restriction’?
Application restrictions
An application restriction controls which websites, IP addresses or applications can use your API key. You can set one application restriction per key.
None
HTTP referrers (websites)
IP addresses (web servers, cron jobs, etc.)
Android apps
iOS apps
API restrictions
API restrictions specify the enabled APIs that this key can call
Don’t restrict key
This key can call any API
Restrict key
Note: It may take up to 5 minutes for settings to take effect.
Currently, I have no restrictions but google doesn’t really like this – they put a warning on it.
If you could point me to the correct setting I would be most grateful.
