Unfortunately not @sssamsss8. Your best bet in such cases would usually be to copy the required curl request from the respective documentation.
Also, be aware that if your relational field in Notion is using the rollup type. Notion currently won’t allow any changes through their API (this is listed under limitations in their documentation).
With Airtables “Linked Record” it should however be possible. Assuming my table looks like this:
The linked column is the “Employee” one. To update this column, I’d use an HTTP Request node like this:
The values you’d need to adjust are the URL: https://api.airtable.com/v0/appwTLCOMpC9wzoUW/Shift%20plan/reck3giqB1NZdlpBO
In this URL you’d need to replace appwTLCOMpC9wzoUW with your actual base ID, Shift plan with your actual table name and reck3giqB1NZdlpBO with the ID of the record you want to update.
You’d also need to update the value of the fields.Employee to match the record you want to link.
Hope this helps!
