Update a table field
update_table_fieldChange one field: its name, description, icon, display format, per-kind configuration (select options, rating maximum …), whether it is required, or a formula’s source/preset. Changing `kind` CONVERTS the stored values — preview it first. A field bound to a resource contract may be relabelled and reformatted but never retyped.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
tableId | string | required | Table ID |
fieldId | string | required | Field ID — get from get_table (fields[].id) |
label | string | optional | Human-readable field name |
config | object | optional | Per-kind configuration: { options: [{ id, label, color }] } for select/status, { maximum, icon } for rating, { multiple } for user, { prefix, digits } for auto number, { accept } for attachment. |
format | object | optional | Display format — { kind: "number", variant: "currency", currency: "AUD", precision: 2 }, { kind: "date", preset: "medium" }. Presentation only; it never rewrites a stored value. |
required | boolean | optional | Reject a row that leaves this field blank |
description | string | optional | Shown in the column tooltip and the API |
icon | string | optional | Icon catalog id, e.g. emoji:store |
kind | "text" | "long_text" | "number" | "checkbox" | "date" | "datetime" | "single_select" | "multi_select" | "status" | "url" | "email" | "phone" | "rating" | "user" | "auto_number" | "attachment" | "json" | "relation" | "formula" | "created_time" | "last_edited_time" | "created_by" | "last_edited_by" | optional | Retype the field. Values that cannot be read as the new kind are cleared, so check first with preview_table_field_retype. |
source | string | optional | New formula source (kind formula) |
preset | object | optional | A structured computed field. Lowered to formula source server-side. |
expectedSchemaVersion | integer | optional | Assert the table schema version you last read. Omit to let the call read it — the write still fails if someone changes the schema in between. |
