Message With My Api Key.

I have been struggling for some time now to get a google earth map in my route building.

I have this message below my API Key that says;

"use this key in your application by passing it with Key=ApI_KEY parameter."

I have been entering the API Key manually but what is the above parameter referring to?

I hope you guys don't get tired of me. I would really like to get past this point so that I can start my project.

 

Did you consider asking Google?
It is their API key you are having a problem with
https://developers.google.com/maps/documentation/javascript/get-api-key

 

Thank you, I have, just now, sent an assistance request to Google. I will let you know how it goes.

 

Thank you 749006. I am up and running. Thread end now.
