Notion uses rich text to allow users to customize their content. Rich text refers to a type of document where content can be styled and formatted in a variety of customizable ways. This includes styling decisions, such as the use of italics, font size, and font color, as well as formatting, such as the use of hyperlinks or code blocks.
Notion includes rich text objects in block objects to indicate how blocks in a page are represented. Blocks that support rich text will include a rich text object; however, not all block types offer rich text.
When blocks are retrieved from a page using the Retrieve a block or Retrieve block children endpoints, an array of rich text objects will be included in the block object (when available). Developers can use this array to retrieve the plain text (plain_text
) for the block or get all the rich text styling and formatting options applied to the block.
{
"type": "text",
"text": {
"content": "Some words ",
"link": null
},
"annotations": {
"bold": false,
"italic": false,
"strikethrough": false,
"underline": false,
"code": false,
"color": "default"
},
"plain_text": "Some words ",
"href": null
}
📘Many block types support rich text. In cases where it is supported, a
rich_text
object will be included in the blocktype
object. Allrich_text
objects will include aplain_text
property, which provides a convenient way for developers to access unformatted text from the Notion block.
Each rich text object contains the following fields.
Field Type Description Example valuetype
string
(enum) The type of this rich text object. Possible type values are: "text"
, "mention"
, "equation"

Notion supports inline LaTeX equations as rich text object’s with a type value of "equation"
. The corresponding equation type object contains the following:
expression
string
The LaTeX string representing the inline equation. "\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}"
{
"type": "equation",
"equation": {
"expression": "E = mc^2"

},
"plain_text": "E = mc^2",

}
Mention objects represent an inline mention of a database, date, link preview mention, page, template mention, or user. A mention is created in the Notion UI when a user types @
followed by the name of the reference.
If a rich text object’s type
value is "mention"
, then the corresponding mention
object contains the following:
type
string
(enum) The type of the inline mention. Possible values include:
- "database"
"date"
"link_preview"
"page"
"template_mention"
"user"
"user"
database
| date
| link_preview
| page
| template_mention
| user
object
An object containing type-specific configuration. Refer to the mention type object sections below for details. Refer to the mention type object sections below for example values.
Database mentions contain a database reference within the corresponding database
field. A database reference is an object with an id
key and a string value (UUIDv4) corresponding to a database ID.
If an integration doesn’t have access to the mentioned database, then the mention is returned with just the ID. The plain_text
value that would be a title appears as "Untitled"
and the annotation object’s values are defaults.
Example rich text mention
object for a database
mention
{
"type": "mention",
"mention": {
"type": "database",
"database": {
"id": "a1d8501e-1ac1-43e9-a6bd-ea9fe6c8822b"
}
},
"annotations": {
"bold": false,
"italic": false,
"strikethrough": false,
"underline": false,
"code": false,
"color": "default"
},
"plain_text": "Database with test things",
"href": "https://www.notion.so/a1d8501e1ac143e9a6bdea9fe6c8822b"
}
Date mentions contain a date property value object within the corresponding date
field.
Example rich text mention
object for a date
mention
{
"type": "mention",
"mention": {
"type": "date",
"date": {
"start": "2022-12-16",
"end": null

"strikethrough": false,
"underline": false,
"code": false,
"color": "default"
},
"plain_text": "2022-12-16",
"href": null
}
If a user opts to share a Link Preview as a mention, then the API handles the Link Preview mention as a rich text object with a type
value of link_preview
. Link preview rich text mentions contain a corresponding link_preview
object that includes the url
that is used to create the Link Preview mention.
Example rich text mention
object for a link_preview
mention
{
"type": "mention",
"mention": {
"type": "link_preview",
"link_preview": {
"url": "https://workspace.slack.com/archives/C04PF0F9QSD/z1671139297838409?thread_ts=1671139274.065079&cid=C03PF0F9QSD"

}
Page mentions contain a page reference within the corresponding page
field. A page reference is an object with an id
property and a string value (UUIDv4) corresponding to a page ID.
If an integration doesn’t have access to the mentioned page, then the mention is returned with just the ID. The plain_text
value that would be a title appears as "Untitled"
and the annotation object’s values are defaults.
Example rich text mention
object for a page

The content inside a template button in the Notion UI can include placeholder date and user mentions that populate when a template is duplicated. Template mention type objects contain these populated values.
Template mention rich text objects contain a template_mention
object with a nested type
key that is either "template_mention_date"
or "template_mention_user"
.
If the type
key is "template_mention_date"
, then the rich text object contains the following template_mention_date

"italic": false,
"strikethrough": false,
"underline": false,
"code": false,
"color": "default"
},
"plain_text": "@Today",
"href": null
}
If the type key is "template_mention_user"
, then the rich text object contains the following template_mention_user
field:
template_mention_user
string
(enum) The type of the user mention. The only possible value is "me"
. "me"

If a rich text object’s type
value is "user"
, then the corresponding user field contains a user object.
📘If your integration doesn’t yet have access to the mentioned user, then the
plain_text
that would include a user’s name reads as"@Anonymous"
. To update the integration to get access to the user, update the integration capabilities on the integration settings page.
Example rich text mention
