I’m building a custom calendar in Notion using Python. But I’m running into an authentication problem. Here’s the error I’m seeing:
raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url: https://www.notion.so/api/v3/loadUserContent
It appears to be related to authentication, though I don’t fully understand what is triggering the error. I’ve confirmed that I’m using the correct integration key and even refreshed it, yet the error persists.
Below is a snippet of my code:
from custom_notion import NotionAPI
# Set up API connection
api_key = 'MY_SECRET_KEY'
notion = NotionAPI(api_key)
# Create new page
workspace = notion.get_workspace()
calendar = workspace.create_page('My 2024 Calendar')
# Add table to the page
table = calendar.add_table()
# Define table columns
table.add_column('Date', 'date')
table.add_column('Mood', 'select', options=['Happy', 'Sad', 'Neutral'])
table.add_column('Notes', 'text')
# Fill in table rows
for day in range(1, 366):
date = f'2024-{day:03d}'
table.add_row(Date=date, Mood='Neutral', Notes='')
print('Calendar created successfully!')
Any suggestions on what might be wrong with the authentication process?
I encountered a similar issue when working with the Notion API for a project tracking tool. The 401 error usually indicates an authentication problem, but it’s not always straightforward.
First, double-check that you’re using the correct API version. Notion has both v1 and v3 endpoints, and mixing them can cause issues. Your error message mentions v3, so ensure your NotionAPI class is set up for that version.
Also, verify that your integration has the necessary permissions. Sometimes, the key is correct, but the integration lacks access to the workspace or specific pages you’re trying to manipulate.
One thing that helped me was using the official Notion Python SDK instead of a custom wrapper. It handles authentication more reliably and provides better error messages.
If none of these solve the problem, try enabling debug logging in your requests to see the full API interaction. This can reveal subtle issues with headers or request formatting that might be causing the authentication to fail.
hey mate, i had similar probs b4. have u tried checkin ur integration settings in notion? sometimes the permissions get messed up. also, make sure ur using the right api version. might wanna try the official notion sdk too, it’s pretty solid. good luck!
I’ve dealt with this exact issue before. The problem likely lies in how you’re initializing the NotionAPI class. Make sure you’re passing the integration token, not the internal integration key. The token should start with ‘secret_’.
Also, check if you’ve actually added the integration to the specific pages or databases you’re trying to access. Notion requires explicit permission for each resource.
Another thing to consider is rate limiting. If you’re making too many requests in quick succession, Notion might temporarily block your access. Try implementing exponential backoff in your code to handle this.
Lastly, ensure your integration has the correct capabilities enabled in the Notion dashboard. Sometimes, certain actions require specific permissions that aren’t enabled by default.
