# CategoryCreate

Allows you to create a new category and set its position within the existing category hierarchy. After you have created a category, you can use the CategorySetPermissions action to specify which role can access this category.

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 must set at least one of Category and Name. By default, Name is the category name, and Category is the ID. However, if you do not set Name, the Category component uses the value of the Category parameter as the category name, and randomly generates an ID for the category.

You can train a category when you create it. This action accepts the same training action parameters as the CategorySetTraining action. When you train the category in this way, the Category component builds the category immediately.

NOTE: If you want to create a Simple category, you must set training by using the CategorySetTraining action. In this case, you must not set training in the `CategoryCreate` action.

If your training information is not valid, or if an error occurs during training, the `CategoryCreate` action returns the new category ID with a success message, but the error string contains a warning to show that the creation step was successful, but training was not.

NOTE: By default, new categories give full access to role members and non-members (so that anyone can view, edit, or delete it).

A category cannot have the same name as another category with the same immediate parent category.
