Registration Fields help capture unique data from registrants, such as location, communication preferences, account information and more. But sometimes what your attendees submit is in a different format than what you need in your downstream workflows. Merge Fields will help combine and transform your fields in vairous ways to help accomplish this.
Merge Fields are able to take any number of your custom registration field values and “merge” them into one field instantaneously. Any selected registration field’s values will be combined into one, and integrated into the CRM system of choice. This one field helps streamline collecting and sifting through all that data, which helps you scan and understand reports faster than before.
