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 ! (U+0021
) through the DEL character
(U+007F
), including most punctuation characters, digits, and upper and
lowercased letters.
