Configure mempool filters from a webhook request

Convert a monitoring request into a focused mempool configuration workflow.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Configure Mempool Filters

Tool to configure filters and abi decoding for ethereum mempool transactions. use after establishing a blocknative websocket connection to set up event filters and decoding.

Why this helps

Filter setup requests arrive in different systems and get delayed before anyone acts.

  • Route setup requests quickly
  • Make filter intent explicit
  • Reduce configuration handoffs

Setup

Build it in a few focused steps.

  • 1Connect Blocknative in Notis once.
  • 2Create an automation named for webhook driven mempool filter setup.
  • 3Tell Notis to use the webhook payload to prepare filters and ABI decoding for the requested transactions.
  • 4Choose a Notis webhook trigger and select the report channel.
  • 5Test with one real filter request.

Questions about this workflow

What must the webhook payload contain?

It should describe the chain, transaction patterns, and decoding details needed for the filter.

Does this open the websocket connection?

The action is intended for use after a Blocknative websocket connection is established.
