Notis

Prepare transaction state monitoring for a delivery request

Keep a transaction hash follow-up ready when an address-sensitive request needs status visibility.

Trigger

Webhook received

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

Action

Subscribe Transaction Hash

Prepares a subscription to status changes for an Ethereum transaction.

Why this helps

A transaction hash can arrive during delivery work and then require a separate manual step to prepare status monitoring.

  • Prepare a subscription message for Ethereum transaction state changes.
  • Keep monitoring preparation tied to the webhook that supplied the hash.
  • Make the next status follow-up easier to start.

Setup

Build it in a few focused steps.

  • 1Connect Addresszen and Blocknative once in the Notis portal.
  • 2Create an automation from Automations, New Automation, or tell Notis from any channel.
  • 3Describe that the webhook should include an Ethereum transaction hash and request the Blocknative subscription message.
  • 4Pick the webhook trigger and choose where run reports should go.
  • 5Test with one real hash and review the prepared subscription message.

Questions about this workflow

Does this action begin monitoring immediately?

No. It prepares the subscription message after a websocket connection is established. It does not establish the connection itself.

What transaction hashes are supported here?
