Notis

Start an Ethereum transaction watch from an HTTP request

Send a transaction hash to a Notis webhook to prepare a Blocknative status subscription without manually rebuilding the request.

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

Transaction hashes shared across campaign or operations tools are easy to lose, and setting up a watch manually takes extra steps.

  • Start the workflow with an HTTP request.
  • Prepare the supported Blocknative transaction hash subscription message.
  • Keep the returned subscription details in a Notis run report.

Setup

Build it in a few focused steps.

  • 1Connect ActiveCampaign and Blocknative once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and describe the transaction watch outcome.
  • 3Tell Notis to use the transaction hash supplied with the request to prepare a Blocknative transaction state change subscription.
  • 4Choose the webhook trigger and report channel, then test with one real transaction hash.

Questions about this workflow

Does this action itself establish a WebSocket connection?

No. The listed action prepares the subscription message after a Blocknative WebSocket connection has been established.

Can ActiveCampaign automatically provide the transaction hash?

ActiveCampaign has no trigger events in this package. The Notis webhook starts the automation when an external system sends an HTTP request with the required transaction hash.
