How to use google API Key into a CDN link get json format for fetch user's current Address?

Question

I want to set User's current location for my website, I use java script geographical location, I got user's longitude and latitude, then I tried to change that into a address format, so I'm using google maps content delivery network link with my google maps applet programming interface key, and then I pass my Content delivery network link with that longitude and latitude on my browser, but it show some JavaScript Object Notation format error message like following code,

{
   "error_message" : "This API project is not authorized to use this API.",
   "results" : [],
   "status" : "REQUEST_DENIED"
}

What should I do for solve this issue ?

I have tried on a e-learn website html geographical location and then I added some java script codes.

I need to show a user current location like an address on my navigation bar, when user click the location icon.

It's not a CDN (Content Delivery Network), which serves files, but an API (Application Programming Interface).

You need to log in to your Google developers console .

Then in the navigation menu on the left, go to APIs & services > Credentials .

Here you have your API keys, you can enable/disable restrictions to applications, domains and IP addresses that can use this key.

Unless you explicitely authorise your application to use this key, access will be denied.
