Optional ReadonlycolumnHow many of its row's columns this field spans: 0 for the whole row, 1-4 for that many columns. An explicit null clears it, leaving the field type's default placement. Read by layout clients; legacy form pages do not apply it.
Optional ReadonlydeprecatedWhether this field is deprecated and hidden from new configurations
Optional ReadonlydisplayWhether the rendered signature displays the signer's credential (the Display Credential option)
Optional ReadonlyexpectedThe field's rowVersion this write was decided against. At that version the write applies and bumps it; one past it with a payload that changes nothing — a replay of a write that already landed — answers success without another bump; anything else is refused with CONCURRENT_MODIFICATION and extensions.currentVersion. Omit to write unconditionally.
Optional ReadonlyfieldID of the field a CUSTOM fieldControlType watches: another checkbox, radio, signature or single-select field on the same form. Null or an empty ID removes it.
Optional ReadonlyfieldVisibility/editability control mode for this field
Optional ReadonlyfieldThe watched field's value at which a CUSTOM fieldControlType applies: true or false for a checkbox or radio, signed or unsigned for a signature, one of its option IDs for a single-select (an empty string, accepted for legacy compatibility, stores no value).
Optional ReadonlyfieldWhat a CUSTOM fieldControlType does to this field while its condition holds. A header, spacer, static content or merge report field can only be HIDDEN, which writing its condition stores.
Optional ReadonlyformulaBlueStep formula expression for computed field values
Optional ReadonlyformulaOptional script/merge variable name (the 'Field Identifier' in the admin UI) used to reference this field from formula, endpoint, and merge-report code. Leave unset for a data-entry-only field that is not referenced from code — like the UI, it is not required.
