What does an API token in IoT Central determine?

An API token in IoT Central primarily serves as an authentication mechanism that determines the level of access granted to the caller. When an application or device sends a request to the IoT Central API, the API token ensures that only authorized clients can interact with the system. This helps to enforce security measures by specifying what resources or operations the authenticated entity can access or perform.

For instance, an API token may allow full access to certain administrative features or limit access to specific devices or telemetry operations depending on the scope and permissions associated with that token. By managing access levels, IoT Central enhances security by preventing unauthorized users from executing actions that could compromise the integrity or functionality of the IoT solution.

While the other options refer to aspects related to IoT Central, they do not reflect the core purpose and functionality of an API token. The application version, type of data processed, and user interface design pertain more to the overall system architecture and user experience rather than the authentication and access control mechanism that an API token provides.
