Review gas costs before confirming an address-sensitive checkout
Get a timely view of transaction fees while you are already checking delivery details.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Gas Prices
Retrieves gas price estimates for likely transaction inclusion.
Why this helps
A shipping check and a blockchain fee check can become two separate tasks, making it easier to miss the cost before confirming a transaction.
- Review current gas estimates alongside an address-related checkout request.
- Reduce extra context switching before a transaction decision.
- Keep the decision with you instead of confirming based only on a fee estimate.
Setup
Build it in a few focused steps.
- 1Connect Addresszen and Blocknative once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis from any channel.
- 3Describe that an incoming address-related checkout webhook should prompt a Blocknative gas estimate for review.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real checkout request and review the returned estimate.
