403 error, hosted on railway.app

Questions
1

Hey there,

I hope someone could help. I am migrating from make.com and wanted to try n8n. The setup was working perfectly until recently, but now I’m getting 403 errors when trying to interact with Airtable through n8n.

Details:

Error: 403 Forbidden - Invalid permissions
Setup: n8n is self-hosted on Railway.app

Using Airtable modules to interact with a base

  • API keys and OAuth tokens are correctly configured.
  • Verified that the permissions for the Airtable base and tables are set correctly.
  • Tested the same operations with make.com, and they work fine.

What I’ve Tried:

  • Double-checked the API key permissions.
  • Recreated the credentials in n8n.

Additional Information:

  • The problem seems to be intermittent, as it was working fine earlier. I’m unsure whether the issue lies with Airtable, Railway.app, or n8n itself.

  • Other parts of my workflow are functioning without any issues.

Hope someone can help.

Cheers

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:

Hey @Roman_J,

Welcome to the community :cake:

A 403 error is pretty standard if something has been forbidden, It sounds like for some reason Airtable may be restricting you.

Depending on the exact error the Airtable docs page here: Airtable API Common Troubleshooting | Airtable Support may help
