Hi @lynton, there is a `required` property you can leverage. From [the docs](https://developers.hubspot.com/docs/methods/workflow-extensions/workflow-extensions-overview): `Indicates whether it is an error to omit the field. Users will not be able to create actions missing required fields. **Optional, but defaults to true.** `
