Request Path Parameters

Parameter	Description
ID	The :ref:`cache-group-id` of a :term:`Cache Group`

fallbacks:	An optional field which, when present, should contain an array of strings that are the :ref:`Names <cache-group-name>` of other :term:`Cache Groups` which will be the :ref:`cache-group-fallbacks`[1]
fallbackToClosest:	A boolean that sets the :ref:`cache-group-fallback-to-closest` behavior of the :term:`Cache Group`[1] Note The default value of fallbackToClosest is true, and if it is null Traffic Control components will still interpret it as though it were true.
latitude:	An optional field which, if present, should be a floating-point number that will define the :ref:`cache-group-latitude` for the :term:`Cache Group`[2]
localizationMethods:	Array of :ref:`cache-group-localization-methods` (as strings) Tip This field has no defined meaning if the :ref:`cache-group-type` identified by typeId is not "EDGE_LOC".
longitude:	An optional field which, if present, should be a floating-point number that will define the :ref:`cache-group-longitude` for the :term:`Cache Group`[2]
name:	The :ref:`cache-group-name` of the :term:`Cache Group`
parentCachegroupId:	An optional field which, if present, should be an integer that is the :ref:`cache-group-id` of a :ref:`cache-group-parent` for this :term:`Cache Group`.
secondaryParentCachegroupId:	An optional field which, if present, should be an integral, unique identifier for this :term:`Cache Group`'s secondary parent
shortName:	An abbreviation of the name
typeId:	An integral, unique identifier for the :ref:`Cache Group's Type <cache-group-type>` Note The actual, integral, unique identifiers for these :term:`Types` must first be obtained, generally via :ref:`to-api-v3-types`.

[1]

(1, 2, 3, 4) Traffic Router will first check for a fallbacks array and, when that is empty/unset/all the :term:`Cache Groups` in it are also unavailable, will subsequently check for fallbackToClosest. If that is true, then it falls back to the geographically closest :term:`Cache Group` capable of serving the same content or, when it is false/no such :term:`Cache Group` exists/said :term:`Cache Group` is also unavailable, will respond to clients with a failure response indicating the problem.

[2]	(1, 2) While these fields are technically optional, note that if they are not specified many things may break. For this reason, Traffic Portal requires them when creating or editing :term:`Cache Groups`.
