Start transaction watches automatically
Make every transaction monitoring request follow the same path.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Subscribe Transaction Hash
Tool to subscribe to transaction state change events of an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the subscription message.
Why this helps
Manual monitoring setup creates missed hashes and inconsistent handoffs between systems.
- Standardize monitoring intake
- Reduce missed transaction hashes
- Create consistent subscription preparation
Setup
Build it in a few focused steps.
- 1Connect TimelinesAI and Blocknative in Notis once.
- 2Create an automation describing the transaction watch outcome.
- 3Tell Notis to validate the webhook transaction hash and prepare a Blocknative transaction hash subscription.
- 4Select a Notis webhook trigger and choose where reports go.
- 5Send one valid test payload and confirm the subscription details.
Questions about this workflow
Can the webhook contain multiple hashes?
Design the prompt and payload contract explicitly if batch handling is needed; each hash must be valid.
Does this remove the subscription later?
No. Use a separate unsubscribe action when monitoring should stop.
