I’m receiving a 401 unauthorized error when fetching workspace data from the Notion API. Check out the sample code:

import requests
from urllib.parse import urljoin

class NotionAPIHandler:
    def __init__(self, token):
        self.token = token
        self.headers = {
            'Authorization': 'Bearer ' + self.token,
            'Content-Type': 'application/json',
            'Notion-Version': '2022-06-28'
        }
        self.base_url = 'https://api.notion.com/v1/'

    def retrieve_page(self, pid):
        endpoint = urljoin(self.base_url, f'blocks/{pid}/children?page_size=100')
        response = requests.post(endpoint, headers=self.headers)
        return response.json()

api_key = 'secret_xxx'
page_identifier = 'page_xyz'
api_client = NotionAPIHandler(api_key)
print(api_client.retrieve_page(page_identifier))

I encountered a similar issue a while back. The error was eventually traced back to two things. First, I double-checked that my API token had proper permissions in the workspace settings on Notion. Notion enforces strict permissions, so any misconfiguration there would cause a 401. Secondly, I found that using the correct HTTP method is crucial. My intended endpoint required a GET request rather than a POST. A mix-up in device endpoints might also lead to unauthorized errors, so verifying both token and endpoint method is essential when troubleshooting.

hey i had similar issue, fixed it by switchin POST to GET and double chekin the permissions on my token. sometimes notion acts weird if token isn’t fresh, so it might help to regenrate it

My experience taught me that subtle mistakes can often precipitate a 401 error. I learned that it’s important to check if the API endpoint requires a strictly defined HTTP method and to ensure that the integration settings are updated in Notion’s dashboard immediately after changes are made. While debugging, I found it useful to inspect the actual headers and the URL construction; sometimes, missing a trailing slash or making a small typographical error in the endpoint path can lead to authorization issues. A more thorough review of the token configuration and endpoint format on the official API docs helped me resolve the issue.

I encountered this error recently and resolved it by checking a few overlooked aspects. It turned out that my API integration in Notion wasn’t fully set up to access the required workspace pages. Verifying that the integration shared permissions with the page in question was a key step. Additionally, it was important to ensure that the token was active and correctly transmitted. In my case, re-issuing the integration token and confirming that the Notion-Version header matched the API documentation resolved the issue completely.

I’ve encountered a similar issue during previous Notion API integrations. I discovered that even slight misconfigurations in token settings or an outdated integration setup could cause 401 errors. In my experience, verifying that the token is correctly associated with the intended workspace and that the integration has full permission to access the required pages was crucial. I also found that minor oversights such as a missing character while copying the API token can result in these issues. A careful review of both the token and the Notion integration settings eventually led to a successful resolution.
