Prepare multichain monitoring cleanup from a webhook
When a monitoring request is complete, turn its close signal into the details needed to clean up subscriptions.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Unsubscribe Multichain
Tool to unsubscribe from events across multiple chains using the multichain sdk. use after stopping monitoring of an address or transaction to clean up resources, e.g., call: blocknative.unsubscribe({ id: '0x..', chainid: '0x1' }).
Why this helps
Finished monitoring can leave subscriptions active because cleanup is another easy-to-miss step.
- Tie cleanup preparation to a clear incoming stop signal.
- Keep relevant unsubscribe details in the run report.
Setup
Build it in a few focused steps.
- 1Connect Blocknative once in Notis.
- 2Create an automation in plain language or in Automations, New Automation.
- 3Ask Notis to prepare Blocknative multichain unsubscribe details from the supplied identifier and chain id.
- 4Choose a webhook trigger and select where reports go.
- 5Test with one real stop request.
