Centralized Solution for Multiple Gmail Accounts in n8n

Questions
1

Hi everyone,

I’ve developed a workflow in n8n that:

  1. Watches emails using a Gmail Trigger.
  2. Uses a Text Classifier to categorize emails (e.g., Leads, Qualified Leads, etc.).
  3. Adds labels to emails based on the classification.

This worked fine when I had just one Gmail account. However, I now need to add six more Gmail accounts, and I want to avoid creating six separate workflows.

I tried adding multiple Gmail Triggers in the same workflow and duplicating the logic for each account, but it quickly became unmanageable. Anytime I need to make a change, I would have to update everything for all accounts, which is time-consuming and error-prone.

Is there a way to:

  • Centralize the logic so I don’t have to duplicate it for each account?
  • Use dynamic inputs or parameters to handle multiple Gmail accounts within a single workflow?

Any guidance or best practices for handling this kind of scenario in n8n would be greatly appreciated!

Thanks in advance!

  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hi @Rohit_Gurav,

This looks like a similar question to this one here: Passing credentials as variables and this is the solution that’s being suggested:

There’s also a feature request to Allow expression for credential selection which might be relevant. Hope that helps :star:
