I can't achieve to create relation ids with notion

Hi everyone,

I can’t find the way to put property with a relation database on Notion create page node.

I know it’s possible by looking at the forum, but I don’t find the way to do it. Can someone explain me ?

Below is a pic of my node, the table on the right is the one with a relation database I would like to update :

  • n8n version: 1.69.2
  • Running n8n via (Docker, npm, n8n cloud, desktop app): n8n cloud
  • Database (default: SQLite): SQLite
  • n8n EXECUTIONS_PROCESS setting (default: own, main): own, main

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hi @aya !

I can’t achieve to share my workflow, do I have to paste the json ?

Also I saw plenty of users achieving to put relation ids database with n8n to notion like this one :

Or is it because it a table view database with relation to database ?

There is no way I can achieve to put a database property like I want to ? If no, when are you gonna launch this future ? Because it’s kind of urgent for me, thanks in advance.

Yes, you can share your workflow by copy & pasting the workflow JSON content in between two block quotes (```).

Tip for sharing your workflow in the forum

Pasting your n8n workflow


Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!


It’s possible to create a two-way relation between databases:

Let’s say you want to connect database B to database A, in order to select database B as a relation under properties, you have to

  • connect both databases A and B to n8n
  • Enable Two-way relation

So it does work as long as you’ve done the above two things, but two-way relations aren’t always good for performance as they can slow down the database so there is a feature request to be able to make a one-way connection instead: [NODE-1494]

Hey man, i stumbled on the same problem. The issue is on the phrasing they choose to describe which id is needed.
On the Relation IDs properties it says

But what it really being needed on that field is the ID of the Row inside that other database (The relation database) you want this item to relate to. If it sounds confusing just read slowly again.

This ID can be found opening that row on a full page and collecting from the UUID showed on the end of URL, I recorded a 1min video going trough more below.

Hope it helps man, and @aya could you guys consider to fix this? I checked a bunch of other similar post before and all of them tried to get the wrong ID because of the deceiving text. Much appreciated

Hi @aya is there an expected date for when one-way relations will be supported (NODE-1494)? I’ve been tracking this since earlier this year (April) and the lack of support has been limiting.

Hi @ledigdev, thanks for the feedback and for putting together a video about it. We’ll make sure to update the description! fix(Notion Node): Fix Relation ID description by ayatnkw · Pull Request #12301 · n8n-io/n8n · GitHub
