Start multichain monitoring from any system
Give forms, scripts, and internal tools one clean monitoring handoff.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Subscribe Multichain
Tool to generate websocket subscription details for events across multiple chains. use when preparing to track a transaction hash or account address across chains via blocknative multichain sdk.
Why this helps
Manual copying between intake systems and monitoring tools causes missed chains and inconsistent coverage.
- Connect any intake system to monitoring
- Cover multiple chains from one request
- Standardize monitoring handoffs
Setup
Build it in a few focused steps.
- 1Connect Blocknative in Notis once.
- 2Create an automation that accepts the webhook payload and prepares a Blocknative multichain subscription.
- 3Choose a Notis webhook trigger and copy its endpoint to the sending system.
- 4Select where run reports should go.
- 5Send one real payload to test the subscription details.
Questions about this workflow
What should the webhook contain?
