How to validate submissions with field rules (schema)

Validation rules let you require specific fields (like email) and reject submissions that don’t match expected types or constraints.

Configure rules in the Workflow tab

  1. Open your form in the dashboard.
  2. Go to Workflow.
  3. Under Field Validation Rules, add fields you expect.
  4. Mark fields as Required when applicable.
  5. Click Save Rules.

What gets rejected

  • Missing required fields
  • Wrong type (for example non-email in an email field)
  • Constraint violations (min/max, length limits, accepted file types)
Extra fields are still accepted

Validation rules focus on required fields and constraints. Submissions can include additional fields not listed in your rules.

Testing tips

  • Submit once with valid data and confirm it appears in Submissions.
  • Then try intentionally missing a required field and confirm you see the error message.
