Zite Database Field Types

The 21 field types you can create through the REST API — their type string, value shape, and key settings (defaults in parentheses).

Computed and system types — rich_text, rollup, created_at, updated_at, updated_by, user — exist inside Zite apps but are platform-managed and can’t be created or configured through this API.

Type	Value	Key settings (defaults)
Text `single_line_text`	`string`	—
Long Text `long_text`	`string` (multi-line)	—
Email `email`	`string` (validated)	—
URL `url`	`string` (validated)	—
Phone `phone_number`	`string` (any formatting)	—
Number `number`	`number \| null`	`decimalPlaces` 0–10 (1), `numberFormat` (local) ¹
Currency `currency`	`number \| null` (raw number)	`currencySymbol` ($), `decimalPlaces` 0–10 (2), `numberFormat` (local) ¹
Percent `percent`	`number \| null` (decimal; `0.5` = 50%)	`decimalPlaces` 0+ (0), `numberFormat` (local) ¹, `showProgressBar` (false), `allowNegative` (false)
Rating `rating`	`number \| null` (int 0–maxRating)	`maxRating` 1–10 (5)
Duration `duration`	`number \| null` (total seconds)	`format` (h:mm) ²
Single Select `single_select`	`string \| null` (option label)	`options[]` of `{ label, color? }` ³
Multiple Select `multiple_select`	`string[]` (labels)	`options[]` of `{ label, color? }` ³
Checkbox `checkbox`	`boolean`	`color` hex (#a8a4ac)
Date `date`	`string \| null` (ISO date, UTC)	`dateFormat` (local) ⁴
DateTime `datetime`	`string \| null` (ISO datetime)	`displayTimeZone` (false), `dateFormat` (local) ⁴, `timeFormat` (12h) ⁵, `timezone` (browser)
Attachments `attachments`	`Array<{ url: string, filename?: string }>`	— (URL must be accessible; `filename` is display-only)
Linked Record `linked_record`	`string[]` (record IDs)	`tableId` (required), `allowMultiple` (true), `inverseFieldId?`, `isInverse?` ⁶
Lookup `lookup`	`any \| any[] \| null` (looked-up values) ⁷	`linkedRecordFieldId` (required), `lookupFieldId` (required) ⁸
Formula `formula`	`string \| number \| Date \| boolean \| any[]` — shape follows `resultType` (read-only)	`expression` (required), `resultType` (required), `formatting?` — see Formula fields
Autonumber `autonumber`	`number \| null` (auto-assigned, read-only)	—
Source `source`	JSONB union, system-set (read-only) ⁹	—

Notes

numberFormat: local (default) · comma_period · period_comma · space_comma · space_period.
Duration format: h:mm (default) · h:mm:ss · h:mm:ss.s · h:mm:ss.ss · h:mm:ss.sss.
options[]: label required; color optional (auto-assigned if omitted); value optional — omit when creating, use in writes to reference existing options (reorder, or keep old + add new). Colors: purple, orange, blue, gray, red, yellow, green, pink, lime, tangerine, emerald, sky, teal, indigo, cyan, violet, fuchsia.
dateFormat: local (default) · long · us · european · iso.
timeFormat: 12h (default) · 24h.
tableId accepts a table ID or name during base creation; creating the field auto-connects both tables in both directions.
Single value if the linked-record field has allowMultiple: false, array if true; element type matches the looked-up field.
Cannot be created during initial base setup — add later via the field-creation endpoint.
{ type: "public_api", apiKeyId? } | { type: "form_submission", flowPublicId, sessionId } | { type: "workflow", workflowId, executionId } | { type: "manual", reason?, userId? } | null.

Formula fields

Formula fields compute their value from other fields using a formula expression. They are read-only and automatically recalculate when referenced fields change. See the Formulas guide for the complete list of supported functions.

{
  "name": "Total Price",
  "type": "formula",
  "template": {
    "expression": "SUM({Price}, {Tax})",
    "resultType": "number",
    "formatting": {
      "numberDisplayType": "currency",
      "decimalPlaces": 2
    }
  }
}

Property	Type	Description
`expression`	string	The formula expression, e.g. `"SUM({Price}, {Tax})"`
`resultType`	string	The output type: `"text"`, `"number"`, `"date"`, `"boolean"`, or `"array"`
`formatting`	object	Optional display formatting (see below)

Formatting options

Numbers — numberDisplayType: "number" (plain) · "currency" (use with decimalPlaces, numberFormat) · "percent" · "duration".
Dates — dateFormat, timeFormat ("12h" or "24h"), timezone, displayTimeZone (whether to show the timezone).

Primary field

The first field in each table is the primary field and must be one of: single_line_text, long_text, date, phone_number, email, url, number, currency, percent, duration, autonumber, formula.

Empty values

Value kind	Empty value
Text	`""`
Number	`null`
Boolean	`false`
Array	`[]`
Object	`null`

Changing a field’s type after data exists can cause data loss if the new type is incompatible with existing values.
