We have a Workflow that uses Notion Resource. Since yesterday we get daily errors and after some investigation we found issue:
Url path contains '/' in the end 'pages/' which causes the issue
After trying the same request in Postman we reproduced error by adding '/' in the end.
Please remove '/' from the path
Additional info:
We use cloud version of Retool
Notion version same old "2022-06-28"
Reproduction API call
-- URL https://api.notion.com/v1/pages
-- Body {"properties":{
"Task name":{"title":[{"text":{"content":"Text"}}]}},
"parent":{"database_id":"DB_ID"}}
-- Headers
--- Notion-Version: 2022-06-28
--- Authorization: NOTION_CONNECTION_TOKEN
Hi - Thanks for flagging this! I was able to see a spike in this 400 error for Notion resources on our end. I have flagged this to our Resource Dev team to investigate further. We will keep you updated!
An update released in Cloud version 3.256 on Tuesday, Aug 19, 2025, should have resolved the issue. Please let us know if youβre still experiencing any problems. Thanks so much for your patience! @anni@edwardfung123
