KB41961: "Google has disabled use of the Maps API for this application. This site is not authorized to use the Google Maps client ID provided..." error message appears when running a document with Google Maps plug-in in MicroStrategy Web.

SYMPTOM:
A popup error message appears when running a document with Google Maps plug-in enabled in Strategy Web 9.x:
 

 
CAUSE:
A possible cause is that the user didn't authorized the right URL to use their client ID.
 
ACTION:
In most cases, the user needs to authorize an application to use their client ID. Applications often use multiple URLs that share a common pattern, e.g. a store locator can live at example.com/stores or at stores.example.com. The user needs to find a URL that will match all URLS their application uses.
 
Note: Authorizing www.example.com will not authorize stores.example.com or any other subdomain of example.com
 
To find the correct URL the user may need to inspect certain HTTP requests from the browser to Google servers.
 
They URL that needs to be authorized is the one in the Refer header for the requests the browser sends to Google to load the API. To capture the request, the user can use tools like Fiddler or Developer Tools included in Google Chrome.
 
After getting one of this tools, follow these steps:
 

1. Start the capturing tool (Fiddler for example)
2. Run the document that is throwing the error in Strategy
3. Stop capturing HTTP traffic.
4. Find the request that tries to load the Maps API.
5. HTTP request headers follow immediately after that line. Find one like: 

Refer: http://www.example.com/microstrategy/...
 
The URL in that line is the one that needs to be authorized.
