Block | Notion

A block object represents a piece of content within Notion. The API translates the headings, toggles, paragraphs, lists, media, and more that you can interact with in the Notion UI as different block type objects.

For example, the following block object represents a Heading 2 in the Notion UI:

Example Block Object

{
	"object": "block",
	"id": "c02fc1d3-db8b-45c5-a222-27595b15aea7",
	"parent": {
		"type": "page_id",
		"page_id": "59833787-2cf9-4fdf-8782-e53db20768a5"
	},
	"created_time": "2022-03-01T19:05:00.000Z",
	"last_edited_time": "2022-07-06T19:41:00.000Z",
	"created_by": {
		"object": "user",
		"id": "ee5f0f84-409a-440f-983a-a5315961c6e4"
	},
	"last_edited_by": {
		"object": "user",
		"id": "ee5f0f84-409a-440f-983a-a5315961c6e4"
	},
	"has_children": false,
	"archived": false,
  "in_trash": false,
	"type": "heading_2",
	"heading_2": {
		"rich_text": [
			{
				"type": "text",
				"text": {
					"content": "Lacinato kale",
					"link": null
				},
				"annotations": {
					"bold": false,
					"italic": false,
					"strikethrough": false,
					"underline": false,

				},
				"plain_text": "Lacinato kale",
				"href": null
			}
		],
		"color": "default",
    "is_toggleable": false
	}
}

Use the Retrieve block children endpoint to list all of the blocks on a page.

Callout
Child database
Child page
Column
Heading 1, when the is_toggleable property is true
Heading 2, when the is_toggleable property is true
Heading 3, when the is_toggleable property is true
Numbered list item
Paragraph
Quote
Synced block
Table
Template
To do
Toggle

The API does not support all block types.

Only the block type objects listed in the reference below are supported. Any unsupported block types appear in the structure, but contain a type set to "unsupported".

Block type objects

Every block object has a key corresponding to the value of type. Under the key is an object with type-specific block information.

Many block types support rich text. In cases where it is supported, a rich_text object will be included in the block type object. All rich_text objects will include a plain_text property, which provides a convenient way for developers to access unformatted text from the Notion block.

Audio

Audio block objects contain a file object detailing information about the audio file.

Example Audio block object

{
  "type": "audio",
  //...other keys excluded
  "audio": {
    "type": "external",
    "external": {
      "url": "https://companywebsite.com/files/sample.mp3"
    }
  }
}

Supported audio types

The following file types can be attached with external URLs in the API as well as in the Notion app UI:

.mp3
.wav
.ogg
.oga
.m4a

A wider set of audio files is supported in the File Upload API and can be attached using a file_upload ID.

Supported file upload types

See the file upload reference for a list of supported file extensions and content types when attaching a File Upload to a block.

Audio blocks only support file types in the “audio” section of the table.

Column list and column

Column lists are parent blocks for columns. They do not contain any information within the column_list property.

Example Column list block object

{
  // ... other keys excluded
  "type": "column_list",
  // ... other keys excluded
  "column_list": {}
}

Columns are parent blocks for any block types listed in this reference except for other columns. They do not require any information within the column property, but a width_ratio number between 0 and 1 can be provided to customize the width of a column relative to others in the same column list. When omitted, the default is to use equal widths for all columns. When provided, width_ratios should add up to 1.

Columns can only be appended to column_lists.

Example Column object

{
  // ... other keys excluded
  "type": "column",
  // ... other keys excluded
  "column": {
    "width_ratio": 0.25
  }
}

When creating a column_list block via Append block children, the column_list must have at least two columns, and each column must have at least one child.

Retrieve the content in a column list

Follow these steps to fetch the content in a column_list:

Get the column_list ID from a query to Retrieve block children for the parent page.
Get the column children from a query to Retrieve block children for the column_list.
Get the content in each individual column from a query to Retrieve block children for the unique column ID.

Divider

Divider block objects do not contain any information within the divider property.

Example Divider block object

{
  //...other keys excluded
  "type": "divider",
  //...other keys excluded
  "divider": {}
}

Embed

Embed block objects include information about another website displayed within the Notion UI. The embed property contains the following information:

Field	Type	Description
`url`	`string`	The link to the website that the embed block displays.

Example Embed block object

{
  //...other keys excluded
  "type": "embed",
  //...other keys excluded
  "embed": {
    "url": "https://companywebsite.com"
  }
}

Differences in embed blocks between the Notion app and the API

The Notion app uses a 3rd-party service, iFramely, to validate and request metadata for embeds given a URL. This works well in a web app because Notion can kick off an asynchronous request for URL information, which might take seconds or longer to complete, and then update the block with the metadata in the UI after receiving a response from iFramely.

We chose not to call iFramely when creating embed blocks in the API because the API needs to be able to return faster than the UI, and because the response from iFramely could actually cause us to change the block type. This would result in a slow and potentially confusing experience as the block in the response would not match the block sent in the request.

The result is that embed blocks created via the API may not look exactly like their counterparts created in the Notion app.

Vimeo video links can be embedded in a Notion page via the public API using the embed block type.

For example, the following object can be passed to the Append block children endpoint:

JSON

{
  "children": [
    {
      "embed": {
        "url": "https://player.vimeo.com/video/226053498?h=a1599a8ee9"
      }
    }
  ]
}

For other video sources, see Supported video types.

Equation

Equation block objects are represented as children of paragraph blocks. They are nested within a rich text object and contain the following information within the equation property:

Field	Type	Description
`expression`	`string`	A KaTeX compatible string.

Example Equation object

{
  //...other keys excluded
  "type": "equation",
  //...other keys excluded
  "equation": {
    "expression": "e=mc^2"
  }
}

File

File block objects contain the following information within the file property:

Field	Type	Description
`caption`	`array` of rich text objects	The caption of the file block.
`type`	One of: - `"file"` - `"external"` - `"file_upload"`	Type of file. This enum value indicates which of the following three objects are populated.
`file`	Notion-hosted file object	A file object that details information about the file contained in the block: a temporary download `url` and `expiry_time`. After the `expiry_time`, fetch the block again from the API to get a new `url`. Only valid as a parameter if copied verbatim from the `file` field of a recent block API response from Notion. To attach a file, provide a `type` of `file_upload` instead.
`external`	External file object	An object with a `url` property, identifying a publicly accessible URL.
`file_upload`	File upload object	An object with the `id` of a FileUpload to attach to the block. After attaching, the API response responds with a type of `file`, not `file_upload`, so your integration can access a download `url`.
`name`	`string`	The name of the file, as shown in the Notion UI. Note that the UI may auto-append `.pdf` or other extensions. When attaching a `file_upload`, the `name` parameter is not required.

Example File block

{
  // ... other keys excluded
  "type": "file",
  // ... other keys excluded
  "file": {
    "caption": [],
    "type": "external",
    "external": {

}

Headings

All heading block objects, heading_1, heading_2, and heading_3, contain the following information within their corresponding objects:

Field	Type	Description
`rich_text`	`array` of rich text objects	The rich text of the heading.

Possible values are: - `"blue"` - `"blue_background"` - `"brown"` - `"brown_background"` - `"default"` - `"gray"` - `"gray_background"` - `"green"` - `"green_background"` - `"orange"` - `"orange_background"` - `"yellow"` - `"green"` - `"pink"` - `"pink_background"` - `"purple"` - `"purple_background"` - `"red"` - `"red_background"` - `"yellow_background"`
`is_toggleable`	`boolean`	Whether or not the heading block is a toggle heading or not. If `true`, then the heading block toggles and can support children. If `false`, then the heading block is a static heading block.

{
  //...other keys excluded
  "type": "heading_1",
  //...other keys excluded
  "heading_1": {
    "rich_text": [{
      "type": "text",
      "text": {
        "content": "Lacinato kale",

  }
}

The link_preview block can only be returned as part of a response. The API does not support creating or appending link_preview blocks.

Mention

A mention block object is a child of a rich text object that is nested within a paragraph block object. This block type represents any @ tag in the Notion UI, for a user, date, Notion page, Notion database, or a miniaturized version of a Link Preview.

Duplicate synced block

Duplicate synced block objects contain the following information within the synced_from object:

Field	Type	Description
`type`	`string` (enum)	The type of the synced from object. Possible values are: - `"block_id"`
`block_id`	`string` (UUIDv4)	An identifier for the original `synced_block`.

Example Duplicate synced block object

{
    //...other keys excluded
  	"type": "synced_block",
    "synced_block": {
        "synced_from": {
            "block_id": "original_synced_block_id"
        }
    }
}

The API does not supported updating synced block content.

Table

Table block objects are parent blocks for table row children. Table block objects contain the following fields within the table property:

Field	Type	Description
`table_width`	`integer`	The number of columns in the table. Note that this cannot be changed via the public API once a table is created.
`has_column_header`	`boolean`	Whether the table has a column header. If `true`, then the first row in the table appears visually distinct from the other rows.
`has_row_header`	`boolean`	Whether the table has a header row. If `true`, then the first column in the table appears visually distinct from the other columns.

Example Table block object

{
  //...other keys excluded
  "type": "table",
  "table": {
    "table_width": 2,
    "has_column_header": false,
    "has_row_header": false
  }
}

table_width can only be set when the table is first created.

Note that the number of columns in a table can only be set when the table is first created. Calls to the Update block endpoint to update table_width fail.

Table rows

Follow these steps to fetch the table_rows of a table:

Get the table ID from a query to Retrieve block children for the parent page.
Get the table_rows from a query to Retrieve block children for the table.

A table_row block object contains the following fields within the table_row property:

Property	Type	Description
`cells`	`array` of array of rich text objects	An array of cell contents in horizontal display order. Each cell is an array of rich text objects.

Example Table row block object

{
  //...other keys excluded
  "type": "table_row",
  "table_row": {
    "cells": [
      [
        {
          "type": "text",
          "text": {
            "content": "column 1 content",
            "link": null

            "code": false,
            "color": "default"
          },
          "plain_text": "column 1 content",
          "href": null
        }
      ],
      [
        {
          "type": "text",
          "text": {

          },
          "annotations": {
            "bold": false,
            "italic": false,
            "strikethrough": false,

            "code": false,
            "color": "default"
          },
          "plain_text": "column 2 content",
          "href": null
        }
      ],
      [
        {
          "type": "text",
          "text": {
            "content": "column 3 content",
            "link": null
          },
          "annotations": {
            "bold": false,
            "italic": false,
            "strikethrough": false,
            "underline": false,
            "code": false,
            "color": "default"
          },
          "plain_text": "column 3 content",
          "href": null
        }
      ]
    ]
  }
}

When creating a table block via the Append block children endpoint, the table must have at least one table_row whose cells array has the same length as the table_width.
