What should the google map api key be?

If I have this URL

http://domain.com/test3/eu/flickr-map/

What url do I use to generate the api key. I have put my code into production and what ever I do I can't seem to get an API key to work.

Please help.

From stackoverflow

• Have you read the FAQ entry about the key and domains?

  You may need to sign up for a new key if you've effectively changed URL.

• I would use "http://domain.com" as my URL when generating the key. That way you can use it within other folders on your site.

• Sign up at this address to get a key for a specific domain then use that key when calling the Google JS files.

  Example: Say I entered a domain at the address above and got a key of:

  ABQIAAAAohKw8F5hsRCukQas4PbQXxS6jl7DzHm5BhVW2hKJ3KnZdh5-DxTaQN7mL8OMRAQtuGL6z2B0_Ql19Q

  I would then use that key in my calls like this:

  <script src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAohKw8F5hsRCukQas4PbQXxS6jl7DzHm5BhVW2hKJ3KnZdh5-DxTaQN7mL8OMRAQtuGL6z2B0_Ql19Q" type="text/javascript"></script>
