You can automatically include some handy variables in your sessions, including:

• The starting workflow name and ID.
• The last workflow name and ID (may be different than the starting workflow if you are using workflow nodes).
• Location data for the end-user. 

To enable these special variables, do the following:

1. Go to the Settings tool, and click the Data tab.
2. Select the variables you want to include in future sessions.

The workflow variables are:

• tree_name - the name of the starting workflow.
• tree_id - the ID number of the starting workflow.
• last_tree_name - The name of the last workflow referenced in the session.
• last_tree_id - The ID of the last workflow referenced in the session.
• container_url - For embedded workflow, the URL that contains your embedded workflow.
