The form designer can define validation rules on a form field. For example, they can set:
- Required fields
- Required format
- Custom rules
When someone submits a form, validation errors will pop up, informing them their input does not match the validation rules.
A CHEFS form field can populate or verify data from an external source by connecting through an unsecured API endpoint. You can do this by writing a javascript pasted into the form field's settings.
