Create List Attribute

The Create List Attribute command allows you to define and create a new List Attribute to use as a Template Tag in your content. Up to fifty (50)* attributes may be defined per Realm.

The Create List Attribute command requires the following arguments: Command, Realm, Password, and List Attribute Name.

api_web?r=myrealm&p=mypass&c=listattrcreate&list_attr_name=myAttribute

The command is ‘listattrcreate', the realm is ‘myrealm’ and the password is ‘mypass’. The new List Attribute named ‘em_list_myattribute’ will be created in all lower case characters.

NOTE: When a List Attribute is created, the 'em_list_' is prepended to the defined name and stored in all lower case characters. When updating or deleting the Attribute, the full name with the prepended string must be used in the Data portion of the command: myAttributeName becomes em_list_myattributename.

Example

Using listattrcreate with all commands and arguments (please note the command is wrapped for display purposes only):

api_web?r=myrealm&p=mypass&c=listattrcreate&list_attr_name=city&list_attr_value=Seattle&list_id=5

Successful results return:

SUCCESS: attribute created

Results

The Create List commands output either a SUCCESS or FAILURE message.

Success

The command success message returns the SUCCESS message. The result format is:

Failure

The command will fail if a List Attribute with the same name already exists, ten attributes already exist, the List does not exist, or invalid data is defined. The result format is:
