Bring token balance context into RSVP follow-up

When a key attendee responds, let Notis fetch ERC20 balances for the wallet relevant to the conversation.

Trigger

Attendee Response Changed

Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.

Action

Get Token Balances

This tool retrieves erc20 token balances for a specified ethereum address. it can either return balances for all tokens an address has ever interacted with or for a specific set of token contract addresses. it is useful for checking token balances for wallets, monitoring erc20 token holdings, portfolio tracking, and defi applications.

Why this helps

RSVP changes can prompt quick follow-up, but gathering wallet context often means leaving the calendar and searching manually.

  • React to accepted, declined or tentative responses with a balance lookup.
  • Use balances for all previously interacted tokens or a supplied contract list.
  • Keep the follow-up context together in a Notis run report.

Setup

Build it in a few focused steps.

  • 1Connect Google Calendar and Alchemy once in the Notis portal.
  • 2Create an automation in Automations, New Automation, or tell Notis from a connected channel.
  • 3In one instruction, ask Notis to retrieve token balances for the relevant wallet when an attendee RSVP changes and summarize the response.
  • 4Choose Attendee Response Changed as the trigger and select where run reports should go.
  • 5Test with one real event and a known wallet address.

Questions about this workflow

Can Notis infer a wallet from the attendee's email address?

No. Supply the wallet address in the event details or automation instruction.

Can this show balances for a particular token list?

Yes, if the contract addresses are supplied. Without them, the action can retrieve balances for tokens the address has interacted with.
