Trigger

Card Archived Trigger

Triggered when a card is archived in the specified board

Action

Unsubscribe Transaction Hash

Tool to unsubscribe from transaction state change events for an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the unsubscription message.

Why this helps

Old subscriptions keep consuming attention after the underlying task is complete or cancelled.

  • Reduce stale monitoring subscriptions
  • Match monitoring lifecycle to task lifecycle
  • Leave an auditable cleanup report

Setup

Build it in a few focused steps.

  • 1Connect Trello and Blocknative in Notis once.
  • 2Create an automation that reads the archived card for its transaction hash and prepares a Blocknative unsubscribe request.
  • 3Choose Trello Card Archived as the trigger.
  • 4Select the report destination.
  • 5Test by archiving one card with a known transaction hash.

Questions about this workflow

What if the transaction was already unsubscribed?

Notis can report the existing state and avoid repeating cleanup when Blocknative indicates it is no longer active.

Does archiving delete the Trello card?

No. The workflow only handles the Blocknative monitoring cleanup.
