MapKit JS. How to obtain file and API key?
I have found that Apple has a Javascript Maps API. I have been researching and I have got as far as obtaining an Apple ID.
MapKIT JS - Maps Apple Developer
For some reason, when I log in, I cannot see a section where I generate an API key.
developer.apple.com
Am I missing something or, do I seriously need to actually buy an Apple computer to be able to download a Javascript library?
