Trigger

Subscribe Trigger

Triggered when a subscriber subscribes to Mailchimp

Action

Get Supported Chains

Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.

Why this helps

New onboarding paths can stall when the chosen network is not supported by the monitoring or fee service.

  • Validate network availability early
  • Reduce onboarding handoff ambiguity
  • Keep chain choices tied to current metadata

Setup

Build it in a few focused steps.

  • 1Connect Mailchimp and Blocknative once in Notis.
  • 2Create an automation named for subscriber chain-fit reviews.
  • 3Describe that Notis should retrieve supported chain metadata after each subscription and compare it with the network context in your onboarding instruction.
  • 4Pick the Subscribe Trigger, choose where reports go, and test with one real subscription.

Questions about this workflow

What happens when no network context is provided?

Notis can return the supported chains and identify the missing onboarding detail.

Can this monitor a transaction?
