You can also use Dynatrace platform tokens[1] against classic endpoints such as Settings Objects[2].
Give your platform token the permission to access the specific account and environment and at least following scopes:
And call the API like this e.g.:
curl -X POST "https://{environmentid}.apps.dynatrace.com/platform/classic/environment-api/v2/settings/objects" \
-H "Authorization: Bearer dt0s16.L4ULG7YU.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '[
