Update Form

Updates a form schema.

Updating formFields replaces the whole array. Any field that's missing from the array you send is moved to deletedFormFields, so resend every field you want to keep.

A field's format validation can't be added or changed once the field exists; doing so is rejected as a backward-incompatible change, since existing submissions may not conform to the new format. To require a format, create a new field instead.

For how to compose each kind of form field, including which identifier, inputType, and componentType values to combine, see About Form Fields.
