Which of the following APIs allows for downloading installers?

The InstallerDownload API is specifically designed to facilitate the downloading of installers for Dynatrace software. This API streamlines the process, allowing users to easily obtain the necessary installation files directly. It serves a crucial function in the setup and deployment of Dynatrace environments, ensuring that users can quickly access the latest installers needed for their applications or infrastructure.

In contrast, the other options do not serve this purpose. The LogImport API is utilized for importing log data into Dynatrace, while the LogExport API is focused on exporting logs from Dynatrace. The ReadSyntheticData API is related to retrieving synthetic monitoring data rather than downloading installers. Therefore, the InstallerDownload API stands out as the appropriate choice for this specific requirement.
