Specification

Parameters and return values

Endpoint: http://127.0.0.1:6806
Unless otherwise stated, API interfaces use the POST method
For interfaces that take JSON parameters, the parameter is a JSON string placed in the body, and the header Content-Type is application/json
Return value
json
```
{
  "code": 0,
  "msg": "",
  "data": {}
}
```
- code: non-zero for exceptions
- msg: an empty string under normal circumstances, an error text will be returned under abnormal conditions
- data: may be {}, [] or NULL, depending on the interface

Behavior semantics

Only interfaces with dedicated interface sections in this document are public APIs. Other kernel routes and /api/transactions operations are internal implementations and provide no compatibility or behavioral stability guarantees unless otherwise stated
code: 0 means the interface reported no error while handling the request. It guarantees only the outcome explicitly documented for that interface; it does not mean that related indexes, caches, WebSocket broadcasts, or sync state have all been updated
The meanings of omitted fields, null, empty objects, and empty arrays are interface-specific. Whether an object or array replaces, merges with, or partially updates existing state, and whether its order is significant, are also defined by each interface
An interface may trim, ignore, complete, or transform input. When its documentation states that a normalized result is returned, callers should use the returned data as the actual accepted result
Do not infer that an operation is read-only from its name. Persistent side effects and their scope are described by each interface when applicable
Repeating the same request is idempotent or safe to retry only when explicitly documented. If a response is interrupted or otherwise indeterminate, read the current state before retrying whenever possible

Authentication

View the API token in <kbd>Settings - Authentication - API token</kbd>. Use it in the request header: Authorization: Token xxx

Database

A database (internally an "attribute view") stores structured data as fields (columns) and items (rows). Each database is identified by an avID and can be embedded into a document through one or more database blocks (blockID). A single database may contain multiple views (viewID) of different layout types: table, gallery, and kanban.

The field types (keyType) are:

Value	Description
`block`	Primary key (bound block)
`text`	Text
`number`	Number
`date`	Date
`select`	Single select
`mSelect`	Multi-select
`url`	URL
`email`	Email
`phone`	Phone
`mAsset`	Asset
`template`	Template
`created`	Creation time
`updated`	Update time
`checkbox`	Checkbox
`relation`	Relation
`rollup`	Rollup
`lineNumber`	Line number

  "groupPaging": {},
  "targetItemID": "",
  "targetGroupID": "",
  "createIfNotExist": true,
  "persistView": true
}
```
- id: Database ID
- blockID: The database block that embeds this database. Used to resolve the active view and publish access. If its custom-sy-av-view is missing or invalid, the first available view is used. Omit when rendering a detached database
- viewID: An explicit view to render. An invalid value returns an error. When omitted, the view is resolved from blockID, then falls back to the first available view
- page: Page number, 1-based. Defaults to 1
- pageSize: Items per page. -1 or omitted means use the view's default (50)
- query: Optional full-text filter for the primary-key values
- groupPaging: Optional paging configuration for grouped (kanban) views
- targetItemID: Optional database item ID to locate. When specified, the response includes target-location metadata
- targetGroupID: Optional group hint used with targetItemID
- createIfNotExist: When true (default), create a database with a default view if the database does not exist
- persistView: Deprecated compatibility parameter. It is accepted but ignored because the database definition no longer stores a top-level current view

Return value (real response, table layout, one row shown):

data.view: The rendered view instance. Its shape depends on viewType: table returns columns/rows/rowCount, while gallery and kanban return fields/cards/cardCount. When grouping is enabled, groups contains a view instance for each group, including groupKey/groupValue. view also carries filters, sorts, group, showIcon, wrapField, groupFolded, and groupHidden. Note: active filters or grouping can make the item list empty even when the total item count is greater than 0
data.view.columns[]: Each has id, name, type, icon, wrap, hidden, desc, calc, numberFormat, template, pin, width; select/mSelect columns additionally carry options
data.view.rows[].id: The table row's item ID (itemID). It also equals value.blockID in that row's primary-key cell. For a bound row, the bound block ID is stored in value.block.id in the primary-key cell; these are distinct concepts and must not be assumed equal
data.view.cards[].id: The item ID (itemID) of a gallery or kanban card. When grouping is enabled, table rows or cards are in the corresponding view instances under groups[]
data.view.rows[].cells[].value: A Value object — see Set a cell value for all value shapes. createdAt/updatedAt are int64 millisecond timestamps
data.views: Metadata of every view (no rows)
data.isMirror: true when the database block is a mirror (read-only copy) of the database

data.av: The full AttributeView definition — fields (keyValues), field ordering (keyIDs, may be null), and all views with their raw layout config (table/gallery/kanban) and item ordering (itemIds). The compatibility viewID is computed as the first available view and is not persisted. Returns no rendered rows or pagination; use Render for computed rows

}
```
- id: Database ID
- keyword: Optional substring filter against primary-key text (case-insensitive)
- page: Page number, 1-based. Defaults to 1
- pageSize: Items per page. -1 or omitted means 16. Values are sorted by block.updated descending

Return value (real response):

json

{
  "code": 0,
  "msg": "",
  "data": {
    "results": [
      {
        "avID": "20240118120204-kwyzf77",
        "avName": "API 测试",
        "viewName": "",
        "viewID": "",
        "viewLayout": "",
        "blockID": "20240118120201-kldj15t",
        "hPath": "正在跟进的问题/数据库/API",
        "children": [
          {
            "avID": "20240118120204-kwyzf77",
            "avName": "API 测试",
            "viewName": "表格",

          }
        ]
      }
    ]
  }
}

data.results[]: Each top-level result groups a database by avID; its children[] list the individual views (viewName/viewID/viewLayout), and matched identifies a view-name match when includeViewMatches is enabled

Set a cell value

Updates a single cell (one field of one row). This is the primary write endpoint for cell values. The request value is a partial Value object whose shape depends on the field's keyType. The most common value shapes are:

`keyType`	`value` shape
`block`	`{"block": {"content": "First row", "id": "<boundBlockID>"}, "isDetached": false}`
`text`	`{"text": {"content": "Some text"}}`
`number`	`{"number": {"content": 42, "isNotEmpty": true}}` (clear with `{"isNotEmpty": false}`)
`date`	`{"date": {"content": 1676042451000, "isNotEmpty": true}}` (millisecond timestamp)
`select`	`{"mSelect": [{"content": "Done", "color": "1"}]}` (at most one option)
`mSelect`	`{"mSelect": [{"content": "A", "color": "1"}, {"content": "B", "color": "2"}]}`
`url`	`{"url": {"content": "https://siyuan.com"}}`
`email`	`{"email": {"content": "[email protected]"}}`
`phone`	`{"phone": {"content": "1234567890"}}`
`mAsset`	`{"mAsset": [{"type": "image", "name": "", "content": "https://example.com/image"}]}`
`checkbox`	`{"checkbox": {"checked": true}}`

⚠️ itemID is the item ID, which is the rendered item's id from Render: rows[].id for a table and cards[].id for a gallery or kanban, inside the corresponding view instance under groups[] when grouping is enabled. It also equals the primary-key value's value.blockID. For a bound item, the bound block ID is stored in the primary-key value's value.block.id; these are distinct concepts and must not be assumed equal. Passing the wrong ID stores the value as an orphan that does not appear in the rendered cell.

For mAsset, each item uses type: "image" to render an image or type: "file" to render a file link. Updating the value replaces the entire mAsset array, so append operations must include the existing items.

/api/av/setAttributeViewBlockAttr
Parameters
json
```
{
  "avID": "20240118120204-kwyzf77",
  "keyID": "20240531232156-ahsyx8l",
  "itemID": "20240118203831-fkfvvtx",
  "value": {
    "type": "number",
    "number": {
      "content": 42,
      "isNotEmpty": true
    }
  }
}
```
- avID: Database ID
- keyID: Field ID (the column being updated)
- itemID: Row ID (rows[].id from Render). The legacy rowID parameter is deprecated and will be removed after 2026-12-01; use itemID instead
- value: Partial Value object (see the table above). Unknown or unsupported keys are ignored

Return value (real response, number value):

json

{
  "code": 0,
  "msg": "",
  "data": {
    "value": {
      "id": "20240531235048-4zisj1p",

        "isNotEmpty": true,
        "format": "",
        "formattedContent": "42"
      }
    }
  }
}

data.value: The fully-normalized value after the update (with computed fields such as number.formattedContent). Use this to refresh the UI rather than re-sending the request payload

Add items

Adds one or more items (rows). Each source can either bind an existing block (isDetached: false) or create a detached row that only lives inside the view (isDetached: true).

/api/av/addAttributeViewBlocks
Parameters
json
```
{
  "avID": "20240118120204-kwyzf77",
  "blockID": "20240118120201-kldj15t",

      "id": "20240118120201-kldj15t",
      "isDetached": false,
      "content": "New row"
    }
  ],
  "ignoreDefaultFill": false
}
```
- avID: Database ID
- blockID: The database block that owns this database (resolves target view/group)
- viewID: Explicit target view. When omitted, the view selected by blockID is used, then the first available view
- groupID: Target group ID for kanban views. Omit for table/gallery
- previousID: Insert after this item ID. Empty means append to the end
- srcs[].id: For bound blocks (isDetached: false), the block ID to bind. Must match the node ID pattern
- srcs[].isDetached: true to create a detached row; false to bind an existing block
- srcs[].content: Display text for the primary key (used when isDetached: true, or to override the bound block's content)
- srcs[].itemID: Optional explicit item ID. Auto-generated when omitted
- ignoreDefaultFill: When true, skip auto-filling default values into filter/group fields
Return value
json
```
{
  "code": 0,
  "msg": "",
  "data": null
}
```
- The endpoint returns null; after it succeeds, call Render to fetch the updated rows (including the new row IDs needed for cell updates)

Remove items

Removes one or more items (rows). Detached rows are deleted; bound blocks are unbound (the underlying document block is not deleted).

/api/av/removeAttributeViewBlocks

Parameters

json

{
  "avID": "20240118120204-kwyzf77",
  "srcIDs": ["20240118203831-fkfvvtx"]
}

avID: Database ID
srcIDs: Row IDs (rows[].id from Render) to remove

Return value

json

{
  "code": 0,
  "msg": "",
  "data": null
}

Change layout

Switches the layout type of the view selected by the database block between table, gallery, and kanban. On success the server re-renders the view and returns it (same shape as Render).

/api/av/changeAttrViewLayout
Parameters
json
```
{
  "avID": "20240118120204-kwyzf77",

  "layoutType": "kanban"
}
```
- avID: Database ID
- blockID: The database block that owns the view
- layoutType: Target layout — one of table, gallery, kanban
Return value: same shape as Render. When switching to kanban and a group is configured, data.view carries a groups[] array; each group is a view instance with groupKey, groupValue, plus kanban-specific fields (coverFrom, cardAspectRatio, cardSize, fitImage, displayFieldName, fillColBackgroundColor, fields)

Set grouping

Sets or clears the grouping rule for a kanban view. When group.field is empty, grouping is removed. On success the server re-renders the view and returns it.
