Which API is used to manage metrics and automate tasks within a specific environment?

The Environment API is designed specifically to manage metrics and automate tasks within a defined environment in Dynatrace. This API serves as the primary interface for interacting with environment-specific metrics, configurations, and resources. It provides the necessary endpoints to retrieve, update, and manipulate data related to the performance and monitoring of applications within a particular environment.

Using the Environment API, developers can automate processes such as creating custom metrics, retrieving monitoring data, and adjusting various settings that pertain solely to the identified environment. This makes it vital for orchestrating and managing the nuances of application performance monitoring in a targeted setting.

In contrast, the other APIs listed serve different purposes. The Account-level API focuses on broader account-wide operations, the Token Management API deals primarily with token lifecycle management, and the Data Access API is concerned with accessing historical data rather than managing metrics or environment-specific tasks.
