Turn a transaction hash in a message into a monitoring subscription
Forward the request once. Abstract pulls out the transaction hash, and Blocknative prepares the subscription so you can follow its status changes.
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 buried in chat or operational notes are easy to miss, and setting up monitoring means switching tools and copying them by hand.
- Start monitoring from a plain language request
- Avoid manually finding and copying a hash
- Prepare a subscription for transaction state changes
Setup
Build it in a few focused steps.
- 1Connect Abstract and Blocknative once in the Notis portal.
- 2Create an automation in Automations, then New Automation.
- 3In one instruction, ask Notis to use Abstract to extract an Ethereum transaction hash from the incoming text and use Blocknative to prepare a subscription for that hash.
- 4Choose the webhook trigger and select where run reports should go.
- 5Test with one real request containing a transaction hash.
Questions about this workflow
What should the webhook request contain?
Include text that clearly identifies an Ethereum transaction hash you want to monitor. Abstract can process the text to extract the hash.
Does this create a live WebSocket connection?
The Blocknative action prepares a transaction hash subscription message after a WebSocket connection is established. The action description does not establish that connection for you.
Can I send any blockchain transaction hash?
This action is specifically for an Ethereum transaction hash. Use a different supported Blocknative action when you need multichain tracking.
