Hello, I’m encountering a critical issue where “Relation” type properties from my Notion databases are not visible in the N8N Notion node.
The core issue: The property is visible in the Notion UI, but it does not appear in the dropdown list for the “Create Page” operation. More importantly, when I use the Database > Get operation (with Simplify turned off) to inspect the database schema, the relation property is completely missing from the output JSON’s properties object.
Troubleshooting steps I have already taken:
Confirmed the N8N integration has “Full access” to both the primary database and the related database.
Tried forcing a cache refresh by re-selecting the database in the node.
Reloaded the entire N8N workflow and restarted the browser.
Deleted and re-created the N8N credentials for Notion.
Deleted the entire integration in Notion and created a new one from scratch.
Restarted my N8N Docker instance.
Tested in a brand new, empty workflow.
Crucially, I deleted the relation property and re-created it. I also created a brand new relation property in a different database, and the issue persists in all cases.
This extensive testing suggests the issue is not a user configuration or caching problem, but likely a deeper issue with the N8N integration or the Notion API itself.
My N8N is self-hosted via Docker, version [1.113.3].
Any help or insight would be greatly appreciated.
Hi @jakejake
The official n8n docs states that the Notion node only supports displaying the data relation property for two-way relations. When you connect two Notion databases with a two-way relationship, you can select or filter by the relation property when working with the Notion node’s Database Page resource.
There are multiple threads on the community forum where users are complaining that relation properties don’t appear. Have a look at these previous post.
Hope this helps
N8N can’t see the details of the relationship field unless you do a couple things first:
- in Notion make sure you have connected the related database to N8N
- in N8N use the Notion Get a Database Page node and pull the related record from the related database using the relation ID that will only show up if you have shared the related database from Notion
Once you have done that then the relation details will be available to use in your automation
