Why are the MapKit APIs no longer available on the Developer Portal?
The MapKit APIs & SDKs are being deprecated in favor of new APIs & SDKs. Although existing licensed users of the MapKit can continue to do so in the short term, they will have to migrate to new TomTom services in the near future. This process will be supported with migration guides and assistance from TomTom. No new licenses will be issued for the MapKit APIs.
Note that because there is no new replacement for the Traffic APIs (Traffic Icons and Segment Flow Data), those will remain available on the Developer Portal under the name Traffic API.
