Usage
Create a New Integration
📘 Before you startMake sure you are an Admin user in your Notion workspace. If you're not an Admin in your current workspace, create a new personal workspace for free.
To create a new integration, follow the steps 1 & 2 outlined in the Notion documentation. The “Internal Integration Token” is what is going to be used to authenticate API calls (referred to here as the “API token”).
📘 Integrations don't have access to any pages (or databases) in the workspace at first. A user must share specific pages with an integration in order for those pages to be accessed using the API.
Declare the API token
Notion.configure do |config|
config.token = ENV['NOTION_API_TOKEN']
endFor Rails projects, the snippet above would go to config/application.rb.
API Client
Instantiating a new Notion API client
client = Notion::Client.newYou can specify the token or logger on a per-client basis:
client = Notion::Client.new(token: '<secret Notion API token>')Pagination
The client natively supports cursor pagination for methods that allow it, such as users_list. Supply a block and the client will make repeated requests adjusting the value of start_cursor with every response. The default page size is set to 100 (Notion’s current default and maximum) and can be adjusted via Notion::Client.config.default_page_size or by passing it directly into the API call.
all_users = []
client.users_list(page_size: 25) do |page|
all_users.concat(page.results)
end
all_users # All users, retrieved 25 at a timeWhen using cursor pagination the client will automatically pause and then retry the request if it runs into Notion rate limiting. (It will pause for 10 seconds before retrying the request, a value that can be overriden with Notion::Client.config.default_retry_after.) If it receives too many rate-limited responses in a row it will give up and raise an error. The default number of retries is 100 and can be adjusted via Notion::Client.config.default_max_retries or by passing it directly into the method as max_retries.
You can also proactively avoid rate limiting by adding a pause between every paginated request with the sleep_interval parameter, which is given in seconds.
all_users = []
client.users_list(sleep_interval: 5, max_retries: 20) do |page|
# pauses for 5 seconds between each request
# gives up after 20 consecutive rate-limited responses
all_users.concat(page.results)
end
all_usersEndpoints
Databases
Query a database
Gets a paginated array of Page objects contained in the database, filtered and ordered according to the filter conditions and sort criteria provided in the request.

If the parent is a database, the new property values in the properties parameter must conform to the parent database's property schema.
properties = {
'In stock': {
'checkbox': true
}
}
client.update_page(page_id: 'b55c9c91-384d-452b-81db-d1ef79372b75', properties: properties)See the full endpoint documentation on Notion Developers.
Retrieve a page property item
Retrieves a property_item object for a given page_id and property_id. Depending on the property type, the object returned will either be a value or a paginated list of property item values. See Property item objects for specifics.
To obtain property_id's, use the Retrieve a database endpoint.
client.page_property_item(
page_id: 'b55c9c91-384d-452b-81db-d1ef79372b75',
property_id: 'aBcD123'
)See the full endpoint documentation on Notion Developers.
Blocks
Retrieve a block
Retrieves a Block object using the ID specified.
📘 If a block contains the keyhas_children: true, use the Retrieve block children endpoint to get the list of children
client.block(block_id: '9bc30ad4-9373-46a5-84ab-0a7845ee52e6')See the full endpoint documentation on Notion Developers.
Update a block
Updates the content for the specified block_id based on the block type. Supported fields based on the block object type (see Block object for available fields and the expected input for each field).
Note The update replaces the entire value for a given field. If a field is omitted (ex: omitting checked when updating a to_do block), the value will not be changed.
to_do = {
'rich_text': [{
'type': 'text',
'text': { 'content': 'Lacinato kale' }

Delete a block
Sets a Block object, including page blocks, to archived: true using the ID specified. Note: in the Notion UI application, this moves the block to the "Trash" where it can still be accessed and restored.
To restore the block with the API, use the Update a block or Update page respectively.
client.delete_block(block_id: '9bc30ad4-9373-46a5-84ab-0a7845ee52e6')See the full endpoint documentation on Notion Developers.
Retrieve block children
Returns a paginated array of child block objects contained in the block using the ID specified. In order to receive a complete representation of a block, you may need to recursively retrieve the block children of child blocks.
