Prepare a watch for transaction changes
When you need to follow a transaction, gather its context and prepare the Blocknative subscription details in one 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
A transaction can stay pending while you switch between context sources and the tools needed to prepare a status watch.
- Gather requested transaction context from websites.
- Prepare a subscription for state changes on an Ethereum transaction hash.
- Keep the returned details with the context for follow-up.
Setup
Build it in a few focused steps.
- 1Connect AgentQL and Blocknative once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis to create it from any channel.
- 3In one instruction, ask AgentQL to gather context from the sources you name and Blocknative to prepare a transaction hash state-change subscription.
- 4Choose the webhook trigger and where run reports should go.
- 5Test with one real Ethereum transaction hash and check the returned subscription details.
Questions about this workflow
Will this notify me of future transaction changes?
The listed action prepares the subscription message after a websocket connection is established. It does not itself establish the connection.
Can I use a non-Ethereum transaction hash?
This action is described for an Ethereum transaction hash. Use the multichain subscription action when preparing monitoring across multiple chains.
