type

ContentType

url

String

The entry point url of the tileset, depending on the content type. This url should be treated as an opaque link as the actual format may change any time. Do not cache it. Any URL manipulation should be done by parsing the URL, rather than through string manipulation. For terrain and imagery, simply append the desired file or tile to the base url. This url should not be cached across application instances as it can change over time.

accessToken

String

The token to be included with each tile request, using Bearer format. This token is different than the access token used throughout the rest of the REST API. It provides access to the content for approximately one hour. To continue using the content after the allotted time, simple re-request the endpoint for a new token.
