This extension adds to CiviCRM’s list of tokens by creating new tokens that reference information from related contacts. For every existing contact token, such as display name or birth date, etc., the extension generates additional related field tokens for every enabled relationship type.

Whereas this extension adds all available tokens -- including all custom fields and other fields, as explained above -- for each relationship type, the "CiviToken" extension adds only 6 tokens (Display Name, First Name, Last Name, Phone, Email, Contact ID) for each relationship type, along with a variety of other customized tokens not derived from relationships.
