Close out transaction hash monitoring cleanly
Include a prepared unsubscribe step in the same closeout flow as the delivery follow-up.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Unsubscribe Transaction Hash
Unsubscribes from status change events for an Ethereum transaction.
Why this helps
A completed follow-up can leave a transaction subscription active when cleanup depends on someone remembering another step.
- Prepare the unsubscribe message for an Ethereum transaction hash.
- Tie monitoring cleanup to a webhook that signals follow-up completion.
- Make transaction monitoring closeout easier to remember.
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 its unsubscribe message after follow-up ends.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real closeout request and review the prepared message.
Questions about this workflow
Does this terminate the websocket connection?
No. It prepares the transaction hash unsubscribe message after establishing a Blocknative websocket connection.
When should this run?
Run it when your external system signals that monitoring for the transaction hash is no longer needed.
