Download browser kernel

API Reference

Request

Download and install browser kernel(s). Supports batch downloading up to 20 kernels per request. The timeout for this operation can be up to approximately 30 minutes; callers should set their timeout to greater than 1805 seconds.

Requires MoreLogin client version 2.61.1 or higher.

Duplicate Request Handling

If the same browser type and major version appears multiple times in a single request, only one lookup and download is performed, but each entry gets its own result.
Concurrent requests for the same version will join the in-flight task instead of starting a new download.
If the requested version is already installed with the latest minor version, the status will be already_installed.
If an older minor version is installed, it will be updated to the latest available minor version.
