Using google maps without API Keys?

Question

I am developing a CMS that will use more than one domain and I have to use only one google map script in my page.

Is there a way to use google maps without API key?<

Answer 1

If you want to vary the API key (for V2) in JavaScript, you can write a wrapper that contains the code for starting your map. The JS code then outputs an API key based upon the host name:

if (document.domain=="[HOSTNAME 1]") {

  document.write('[JS TAG to Google Maps API with HOSTNAME 1 Key]')

} else if (document.domain=="[HOSTNAME 2]") {

  document.write('[JS TAG to Google Maps API with HOSTNAME 2 Key]')

etc...
