In this walkthrough, you'll learn how to link records between NocoDB tables using a raw HTTP request inside n8n.
We’re working with a real many-to-many setup and covering:
- How to understand source vs. target in link relationships
- Where to find the actual linkFieldId (not the fake one)
- How to build the right request payload (without trial-and-error hell)
- What errors like “Primary key not found” really mean
- How to test and confirm the link worked
Tools used:
- 🧱 NocoDB (self-hosted)
- ⚙️ n8n (self-hosted)
- 📡 HTTP Node (manual API call)
p.s.: After I shared the video, a friend, Oliver, pointed out that you do NOT need to make a Formula column, rather just select on "Fields" and toggle "Show System Fields" -- Thanks Oliver for teaching me that!!! 💖🔥
