+# Folder API
+
+## Identifier (id) vs 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 URL's 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.
+
+
