Start a live pending transaction watch when a review needs it
Kick off a focused mempool watch for EVM activity from an HTTP request and keep the results easy to review.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Mempool Subscription
Why this helps
Pending transactions can move quickly, while manual setup adds friction when a timely watch is needed.
- Subscribe to real-time mempool updates for supported EVM chains.
- Start the watch from an incoming request.
- Keep the query scope and chain visible in run reporting.
Setup
Build it in a few focused steps.
- 1Connect Adtraction and Bitquery once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name the pending transaction watch.
- 3In one instruction, ask Notis to construct a mempool subscription for the specified EVM chain and summarize relevant pending activity.
- 4Pick the Notis webhook trigger and choose where run reports should go.
- 5Test with one real example specifying an EVM chain and the activity to watch.
Questions about this workflow
Does this cover confirmed historical transactions?
No. A mempool subscription streams pending transactions. Use an archive or database query for historical confirmed activity.
What if the request does not name an EVM chain?
The workflow should ask for the missing chain detail or report that it cannot safely start the subscription.
