Property values

A property value defines the identifier, type, and value of a page property in a page object. It's used when retrieving and updating pages, ex: Create and Update pages.

🚧

Property values in the page object have a 25 page reference limit

Any property value that has other pages in its value will only use the first 25 page references. Use the Retrieve a page property endpoint to paginate through the full value.

All property values

Each page property value object contains the following keys. In addition, it contains a key corresponding with the value of type. The value is an object containing type-specific data. The type-specific data are described in the sections below.

Title property values

Title property value objects contain an array of rich text objects within the title property.

{
  "Name": {
    "title": [
      {
        "type": "text",
        "text": {
          "content": "The title"
        }
      }
    ]
  }
}

{
  "title": {
    "title": [
      {
        "type": "rich_text",
        "rich_text": {
          "content": "The title"
        }
      }
    ]
  }
}

📘

The Retrieve a page endpoint returns a maximum of 25 inline page or person references for a title property. If a title property includes more than 25 references, then you can use the Retrieve a page property endpoint for the specific title property to get its complete list of references.

Rich Text property values

Rich Text property value objects contain an array of rich text objects within the rich_text property.

Formula property values

Formula property value objects represent the result of evaluating a formula described in the
database's properties. These objects contain a type key and a key corresponding with the value of type. The value of a formula cannot be updated directly.

🚧

Formula values may not match the Notion UI.

Formulas returned in page objects are subject to a 25 page reference limitation. The Retrieve a page property endpoint should be used to get an accurate formula value.

{
  "Formula": {

Relation property value objects contain an array of page references within the relation property. A page reference is an object with an id key and a string value (UUIDv4) corresponding to a page ID in another database.

A relation includes a has_more property in the Retrieve a page endpoint response object. The endpoint returns a maximum of 25 page references for a relation. If a relation has more than 25 references, then the has_more value for the relation in the response object is true. If a relation doesn’t exceed the limit, then has_more is false.

Note that updating a relation property value with an empty array will clear the list.

{
  "Project": {
    "relation": [
      {
        "id": "1d148a9e-783d-47a7-b3e8-2d9c34210355"

  }
}

Rollup property values

Rollup property value objects represent the result of evaluating a rollup described in the

    ]
  }
}

📘

When updating a file property, the value will be overwritten by the array of files passed.
