Look up supported chains when a request arrives
Give an intake process a current network reference without asking someone to look it up and relay it by hand.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Why this helps
Network support questions interrupt work while someone searches for the current list of supported chains.
- Start the lookup from an HTTP request.
- Retrieve current supported chain metadata from Blocknative.
- Prepare a compact reference for the workflow that needs it.
Setup
Build it in a few focused steps.
- 1Connect Blocknative once in the Notis portal.
- 2Create an automation in the portal or tell Notis in plain language.
- 3In one instruction, ask Notis to retrieve supported chain metadata and summarize it for the intake request.
- 4Pick a webhook trigger and use the generated request endpoint in your intake process.
- 5Choose a report channel and test with one real request.
Questions about this workflow
Does the workflow validate a specific transaction?
No. This action retrieves supported chain metadata, not transaction validity or status.
What starts a webhook workflow?
An HTTP request to the automation's webhook endpoint starts it.
