# CategoryFindByFields

Allows you to specify one or more field names and values to return the IDs of all categories that contain the specified values in the specified fields. The field name matching is case insensitive.

NOTE: This is an administrative action that can be sent only by users that belong to an authorization role that allows the `Admin` standard role, or which enables the action explicitly. See Authorization Roles Configuration Parameters.

You set the fields and values in Fields and Values. The number of field values specified must match the number of field names specified, and the order of the values must match the order of the names.

NOTE: You create user-defined fields in categories by using the CategorySetDetails action.
