Trello Trigger counts an execution for every board event — high execution usage

[Vlad26]

Hi everyone

I’ve encountered a problem with how Trello Trigger works in n8n Cloud, and I’d like to understand if there’s a better way to optimize executions.

I have a workflow where:

• The Trello Trigger listens to a specific board (using Model ID = boardId)

• Then I immediately filter the incoming events with a Function node to process only when a card is created or moved into specific lists (e.g., “Bugs” or “Technical Review”)

• All other events (updateCard, deleteCard, etc.) are ignored with return [] right away.

  Even though my Function node exits early and does no further processing,
  each Trello event still counts as a full workflow execution in n8n Cloud.

  Trello sends a lot of webhook events for every small change (labels, comments, renames, etc.), so these executions add up extremely fast, even if I don’t use them.

  I’ve confirmed this by checking:

  • Executions are recorded (even those lasting <50 ms)

  • “Save Successful Executions” = None → they don’t appear in logs, but still count towards my plan’s execution quota.

    To reduce unnecessary executions and only process Trello events related to specific lists or actions — ideally without setting up an external proxy or separate webhook gateway.
