pathPrefix

The path prefix for filtering the results. For example, the prefix /division_abc/subdivision_xyz/ gets all groups whose path starts with /division_abc/subdivision_xyz/.

This parameter is optional. If it is not included, it defaults to a slash (/), listing all groups. This parameter allows (through its regex pattern) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! (\u0021) through the DEL character (\u007F), including most punctuation characters, digits, and upper and lowercased letters.
