Grafana Folders API
Folders are identified by the identifier (id) and the unique identifier (uid). The identifier (id) of a folder is an auto-incrementing numeric value and is only unique per Grafana install. The unique identifier (uid) of a folder can be used for uniquely identify folders between multiple Grafana installs. It’s automatically generated if not provided when creating a folder. The uid allows having consistent URLs for accessing folders and when syncing folders between multiple Grafana installs. This means that changing the title of a folder will not break any bookmarked links to that folder. The uid can have a maximum length of 40 characters.
