When you query a database, you can send a filter object in the body of the request that limits the returned entries based on the specified criteria.

For example, the below query limits the response to entries where the "Task completed" checkbox property value is true:

curl -X POST 'https://api.notion.com/v1/databases/897e5a76ae524b489fdfe71f5945d1af/query' \
  -H 'Authorization: Bearer '"$NOTION_API_KEY"'' \
  -H 'Notion-Version: 2022-06-28' \
  -H "Content-Type: application/json" \
--data '{
  "filter": {
    "property": "Task completed",
    "checkbox": {
        "equals": true
   }
  }
}'

Here is the same query using the Notion SDK for JavaScript:

const { Client } = require('@notionhq/client');

const notion = new Client({ auth: process.env.NOTION_API_KEY });
// replace with your own database ID
const databaseId = 'd9824bdc-8445-4327-be8b-5b47500af6ce';

const filteredRows = async () => {
	const response = await notion.databases.query({
	  database_id: databaseId,
	  filter: {
	    property: "Task completed",
	    checkbox: {
	      equals: true
	    }
	  },
	});
  return response;
}

Filters can be chained with the and and or keys so that multiple filters are applied at the same time. (See Query a database for additional examples.)

{
  "and": [
    {
      "property": "Done",
      "checkbox": {
        "equals": true
      }
    }, 
    {
      "or": [
        {
          "property": "Tags",
          "contains": "A"
        },
        {
          "property": "Tags",
          "contains": "B"
        }
      ]
    }
  ]
}

If no filter is provided, all the pages in the database will be returned with pagination.

The filter object

Each filter object contains the following fields:

FieldTypeDescriptionExample value
propertystringThe name of the property as it appears in the database, or the property ID."Task completed"
checkbox
date
files
formula
multi_select
number
people
phone_number
relation
rich_text
select
status
timestamp
ID
objectThe type-specific filter condition for the query. Only types listed in the Field column of this table are supported.

Refer to type-specific filter conditions for details on corresponding object values.
"checkbox": { "equals": true }
{
  "filter": {
    "property": "Task completed",
    "checkbox": {
      "equals": true
    }
  }
}

The filter object mimics the database filter option in the Notion UI.

        "property": "ID",
        "unique_id": {
          "less_than": 3
        }
      }
    ]
  }
}

Compound filter conditions

You can use a compound filter condition to limit the results of a database query based on multiple conditions. This mimics filter chaining in the Notion UI.

1340

An example filter chain in the Notion UI

The above filters in the Notion UI are equivalent to the following compound filter condition via the API:

{
  "and": [
    {
      "property": "Done",
      "checkbox": {
        "equals": true
      }
    }, 
    {
      "or": [
        {
          "property": "Tags",
          "contains": "A"
        },
        {
          "property": "Tags",
          "contains": "B"
        }
      ]
    }
  ]
}

A compound filter condition contains an and or or key with a value that is an array of filter objects or nested compound filter objects. Nesting is supported up to two levels deep.

FieldTypeDescriptionExample value
andarrayAn array of filter objects or compound filter conditions.

Returns database entries that match all of the provided filter conditions.
Refer to the examples below.
orarrayAn array of filter objects or compound filter conditions.

Returns database entries that match any of the provided filter conditions
