Notis

Start multichain monitoring from a webhook

Let your deployment or operations system hand monitoring context directly to Notis.

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

Automated systems may produce wallet or transaction data without a simple path to start cross-chain monitoring.

  • Connect existing systems without manual entry
  • Start monitoring immediately after an event
  • Support multiple networks in one workflow

Setup

Build it in a few focused steps.

  • 1Connect Google Super and Blocknative once in the Notis portal.
  • 2Create an automation named Webhook wallet multichain subscription.
  • 3Tell Notis to read the incoming wallet or transaction context and prepare the matching Blocknative multichain subscription.
  • 4Choose an HTTP webhook trigger and choose a report channel.
  • 5Test by sending one real webhook payload.

Questions about this workflow

What should the webhook include?

Include the wallet address or transaction identifier and the chain context needed for monitoring.

Can one payload include several networks?

Yes. Ask Notis to prepare a multichain subscription from all valid network and identifier data in the payload.
