Check NFT ownership after a calendar record changes
Keep token ownership checks close to changing deal notes.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
Action
Get NFT Owners
This tool retrieves the owner(s) for a specific nft token, supporting both erc721 and erc1155 tokens on ethereum and several layer 2 chains such as polygon, arbitrum, optimism, and base. it requires the contract address and tokenid, and returns a list of owner addresses along with an optional pagination key for further results.
Why this helps
Ownership details can become outdated while negotiations and meeting plans change.
- Recheck ownership after important updates
- Tie token checks to operational changes
- Create a clear report for follow up
Setup
Build it in a few focused steps.
- 1Connect Google Super and Alchemy once in Notis.
- 2Create an automation for updated token review events.
- 3Tell Notis to extract the NFT contract and token ID from the changed event details and retrieve the owners.
- 4Pick Event Updated as the trigger and choose a report channel.
- 5Test by updating one event with a known token reference.

Supported Triggers and Actions
Notis builds workflows that link Google Super to Alchemy. A trigger fires from one place; an action lands in another.
Google Super triggers
Alchemy actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Get NFT Contract Metadata
This tool retrieves metadata for a given nft smart contract. essential for obtaining basic nft collection details such as contract name, symbol, total supply, token type (erc721 vs erc1155), contract deployer address, deployed block number, opensea metadata, and contract verification status.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get NFT Sales
This tool will retrieve nft sales data across various marketplaces. it allows users to query historical nft sales data with filtering options such as fromblock, toblock, order, marketplace, and limit in order to track nft sales activity, analyze historical data, monitor specific collections, and get real-time updates on nft transactions.
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
Get NFTs for Contract
This tool retrieves all nfts for a given contract address. it is designed to return a complete list of nfts from a specific nft collection by accepting parameters such as contractaddress (required), withmetadata (optional), pagesize (optional), and pagekey (optional). the tool is useful for analyzing collections, building nft marketplaces, and creating collection analytics.
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Get NFT Owners
This tool retrieves the owner(s) for a specific nft token, supporting both erc721 and erc1155 tokens on ethereum and several layer 2 chains such as polygon, arbitrum, optimism, and base. it requires the contract address and tokenid, and returns a list of owner addresses along with an optional pagination key for further results.
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
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.
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Get Token Metadata
This tool retrieves metadata for a given token contract address, including the token's name, symbol, decimals, and logo url if available. it is essential for applications that need to display token information, handle token transfers, or manage token listings.
Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
Get Transaction Count
This tool retrieves the number of transactions sent from a specific address (also known as the nonce). it uses the eth gettransactioncount endpoint to return the transaction count for an address at a specified block tag (latest, pending, earliest, or a hex block number), which is essential for determining the nonce for subsequent transactions.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
