# Meegle API — Setting (Field Settings)

APIs under this skill: Get Field Information, Create Custom Field, Update Custom Field.

---

## Get Field Information

Obtain the basic information of all fields under the specified space or, when **work_item_type_key** is provided, under that work item type. Response follows the SimpleField structure (field_key, field_type_key, options for select, compound_fields for compound_field). Permission: Permission Management – Configuration.

### When to Use

- When building field selectors or form UIs that need field keys, types, aliases, and scopes (work_item_scopes)
- When you need option lists for select-type fields (label, value, order, is_disabled, etc.) or sub-fields for compound_field
- When resolving field_key for Update Work Item Basic Information Settings (schedule_field_key, estimate_point_field_key, actual_work_time_field_key) or for work item read/write APIs

### API Spec: get_field_information

```yaml
name: get_field_information
type: api
description: >
  Obtain all fields under the space or under a work item type. Returns SimpleField
  list: field_key, field_type_key, field_alias, field_name, is_custom_field,
  work_item_scopes, value_generate_mode, relation_id; options for select; compound_fields for compound_field.

auth:
  type: plugin_access_token
  header: X-Plugin-Token
  user_header: X-User-Key

http:
  method: POST
  url: https://{domain}/open_api/{project_key}/field/all
  headers:
    Content-Type: application/json
    X-Plugin-Token: "{{resolved_token}}"
    X-User-Key: "{{user_key}}"

path_params:
  project_key:
    type: string
    required: true
    description: >
      Space ID (project_key) or space domain name (simple_name).
      project_key: Double-click space name in Meegle. simple_name: from space URL (e.g. doc).

inputs:
  work_item_type_key:
    type: string
    required: false
    description: Work item type. Obtain via Get work item types in space. Omit to get all fields in space.

outputs:
  data:
    type: array
    description: >
      List of SimpleField. Each has field_key, field_type_key, field_alias, field_name,
      is_custom_field, work_item_scopes, value_generate_mode, relation_id. Select-type
      fields include options (order, color, is_visibility, is_disabled, label, value,
      work_item_type_key). compound_field type includes compound_fields (array of
      field objects with field_key, field_type_key, field_name, etc.).

constraints:
  - Permission: Permission Management – Configuration

error_mapping:
  30001: Data not found (project_key does not match work_item_type_key; no such work item type in this space)
```

### Usage notes

- **work_item_type_key**: Omit to return all fields in the space; set to a type (e.g. `story`, `chart`) to return only fields scoped to that type. If the type does not exist in the space, 30001 is returned.
- **data** items: Use **field_key** when updating work item type settings (schedule_field_key, etc.) or when sending field values in work item APIs. **field_type_key** (e.g. `multi_text`, `select`, `compound_field`) determines value shape.
- **options**: For **select** (and similar) fields; **value** is what to send in API payloads; **label** is display. **compound_fields**: For **compound_field** type; each sub-field has its own field_key and field_type_key.

---

## Create Custom Field

Create a new custom field under the specified work item type. Returns the new **field_key**. Permission: Permission Management – Work Item Instances. For feature details, see Permission Management.

### Points to note

- Work item relationship field default data visibility is fixed; conditional data range cannot be modified.
- Default values are not supported for attachment type or for external system signal / multi-value external system signal.
- Modifying field validity (default valid) is not supported.
- Updating work item type, creator, submission time, completion time, and business line fields is not supported.
- Voting fields are not supported.

### When to Use

- When adding a new custom field (text, select, date, user, number, link, etc.) to a work item type
- When reusing options from another field (value_type 1 + reference_work_item_type_key, reference_field_key) or defining custom options (field_value)
- When configuring team_option for cascading single/multi-select (tree_select, tree_multi_select); mutually exclusive with field_value

### API Spec: create_custom_field

## Update Custom Field

Update the configuration of the specified custom field. Identify the field by **field_key** in the body. Permission: Permission Management – Configuration. For details, see Permission Management.

### Points to note

### Usage notes

- **field_key**: Required to identify which field to update; from **Get Field Information**. For **compound_field**: use parent **field_key** to change only name/alias/help_description; use child **field_key** to update all attributes.

- **field_value** vs **team_option**: Do not send both. Use **field_value** for option list changes; use **team_option** for team scope on tree_select / tree_multi_select.
- Default values are not supported for attachment, external system signal, or multi-value external system signal.
