Velocity Overview

Reteno uses Velocity, an open-source templating language, to work with dynamic data in messages and workflows.

With Velocity, you can insert contact field values into content, render event data passed through a triggered workflow, apply conditions, and use values returned from external sources.

Where Velocity Gets Data

Velocity works with data already available in Reteno, including contact fields, event data, and external sources.

For the full data model, source availability, and precedence rules, see Overview.
