Schema – Data: Limitations and Restrictions

  • Updated

This article outlines the supported user interface data types, their system-enforced restrictions, and important behavioral notes to consider when designing objects, fields, and forms in the Data workspace.

Understanding these limitations helps admins design scalable data models, avoid validation issues, and ensure compatibility across forms, automations, and integrations.

Notes and Best Practices

  • Character limits apply per value, not per field, unless otherwise stated.
  • List-type fields generally have no limit on item count, but each item is individually validated.
  • Validation rules (email, phone, zip code) are enforced at the user interface and data layer.
  • Address fields are highly configurable, but linked dependencies (City → County) are always preserved.
  • Calculated fields inherit the same limitations as their resulting data type once enabled.
