I got the message about needing to get a Bing maps key to use Bing in my online maps but Im not finding much in the way of directions on what to do. I went to bing and it asks for the application URL. Is that the URL of each individual map that uses Bing or is there a url to my ArcGIS online account somewhere that I use for this? After I have the key do I need to enter it in my account online somewhere? If so I cant find where.
