# Fields Source: https://neondeerdata.com/docs/api/lookup-tables/fields/ Add fields and change their names, types, or workflow access. ## Add field ```http POST /v1/lookup-tables/{table_id}/fields ``` Adds a field to a table, at the version you read. Its key is made from its name when you leave it out. Requires `lookup_tables:config:write`. The connection also needs access to the relevant tables, objects, or workflows. MCP action: `create_lookup_field`. Its argument names match the fields below; an HTTP header is passed using its argument name in MCP. ### Parameters | Name | Send in | Required | Type or allowed values | Notes | | ------------------- | ------------------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------- | ----- | | `table_id` | path | Yes | string | | | `name` | JSON body | Yes | string | | | `key` | JSON body | No | string | | | `type` | JSON body | Yes | `"text"`, `"number"`, `"boolean"`, `"date"`, `"timestamp"`, `"email"`, `"phone"`, `"domain"`, `"url"`, `"member"`, `"record"` | | | `workflow_readable` | JSON body | No | boolean | | | `expected_version` | JSON body | Yes | integer | | | `request_key` | Header: `Idempotency-Key` | Yes | string | | ### Response | HTTP status | Result | | ----------- | --------------------------------------------------------------------- | | `201` | The requested result.

A field used by a workflow or a lookup keeps its type. Changing the type converts every value, and a large table's change is answered with 202: get the settings until pending_work is null. Values a type change replaces are not kept, so it can't be undone. Requires `lookup_tables:config:write`. The connection also needs access to the relevant tables, objects, or workflows. MCP action: `update_lookup_field`. Its argument names match the fields below; an HTTP header is passed using its argument name in MCP. ### Parameters | Name | Send in | Required | Type or allowed values | Notes | | ------------------- | --------- | -------- | ----------------------------------------------------------------------------------------------------------------------------- | ----- | | `table_id` | path | Yes | string | | | `field_id` | path | Yes | string | | | `expected_version` | JSON body | Yes | integer | | | `name` | JSON body | No | string | | | `type` | JSON body | No | `"text"`, `"number"`, `"boolean"`, `"date"`, `"timestamp"`, `"email"`, `"phone"`, `"domain"`, `"url"`, `"member"`, `"record"` | | | `workflow_readable` | JSON body | No | boolean | | ### Response | HTTP status | Result | | ----------- | --------------------------------------------------------------------- | | `200` | The requested result.

This can't be undone. Requires `lookup_tables:config:write` and `lookup_tables:delete`. The connection also needs access to the relevant tables, objects, or workflows. MCP action: `archive_lookup_field`. Its argument names match the fields below; an HTTP header is passed using its argument name in MCP. ### Parameters | Name | Send in | Required | Type or allowed values | Notes | | ------------------ | --------- | -------- | ---------------------- | ----- | | `table_id` | path | Yes | string | | | `field_id` | path | Yes | string | | | `expected_version` | JSON body | Yes | integer | | ### Response | HTTP status | Result | | ----------- | --------------------------------------------------------------------- | | `200` | The requested result.
