With the default value text transformation in Formatter, you can set a fallback value for fields that may not always have a value provided by a previous step.
You have a web form that collects leads and the Name field is optional but your CRM requires it. You can set a default value of “Unknown” so that anyone that doesn't fill out their name still gets passed to your CRM.
Before you can add Formatter to a Zap, you’ll first need to set up your Zap trigger.
A field may also be blank because the trigger test does not contain that field, or the name of the field changed. Before implementing the solution below, make sure to get new trigger test data so you have all current field names.
