Update Smart Form

Update the configuration of an existing smart form

Scope: SMART_FORMS_WRITE

Overview

Updates one or more fields on an existing smart form. All body fields are optional — only the provided fields are updated. Published forms can only have their title updated; all other fields require the form to be in DRAFT status.

Request Body

All fields are optional. Omit fields you do not want to change.

Published Form Restrictions

Once a smart form is published, only the title field can be updated. Attempting to update any other field on a published form returns a 400 error. To change other fields, unpublish the form first.
