Prepare transaction watch cleanup from Ably

When the team says a transaction no longer needs attention, capture the request and prepare the matching unsubscribe details.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

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

Transaction monitoring can linger after the team has moved on, leaving cleanup as an easy-to-forget follow-up.

  • Capture a clear stop request arriving through Ably.
  • Prepare unsubscription details for the specified Ethereum transaction hash.
  • Include missing hash information in the run report for quick follow-up.

Setup

Build it in a few focused steps.

  • 1Connect Ably and Blocknative once in the Notis portal.
  • 2Create an automation in Automations, then New Automation, and name the cleanup workflow.
  • 3Tell Notis to extract the Ethereum transaction hash from a stop request and prepare Blocknative unsubscription details.
  • 4Choose the webhook trigger and where run reports should go. Configure Ably to send matching stop requests to the Notis webhook.
  • 5Test with one real transaction hash and confirm the report includes the prepared cleanup details.

Questions about this workflow

What does the webhook need to contain?

It needs the Ethereum transaction hash for the subscription to stop.

Can this action unsubscribe from multichain events?

No. This action is for an Ethereum transaction hash. Use the multichain unsubscribe action for multichain monitoring.
