I'm wanting to upgrade a current site to use the RedHen CRM module to track contact engagement (etc.) but first need to create RedHen contacts (redhen_contact module) for each of the users. I'm familiar with Drush scripts so would be fine writing up a script but I'm unfamiliar with the internals of how RedHen works in Drupal. Is there anybody who knows it already who might be able to help point the way?
Note: This is not a third-party api. It's a CRM built within Drupal as a Drupal module. What I'm asking is the proper form to utilize the Entity API to create contacts within the RedHen CRM module programmatically.
