Check NFT contract details after a Drive share
A newly shared collection brief can prompt a quick contract metadata check, so you can review the collection basics alongside the document.
Trigger
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
Action
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.
Why this helps
Contract details can be easy to overlook when a collection brief arrives as a Drive share and you have to switch tools to verify it.
- Review collection name, symbol, supply, token type, and verification details in the context of a new share.
- Reduce manual tool switching when a collaborator shares a collection brief.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, ask Notis to find an NFT contract address in the shared item's available content and retrieve its metadata; if no address is present, report that it is missing.
- 4Pick the Google Drive File Shared trigger and choose where run reports go.
- 5Test with one real shared item that contains an NFT contract address.
Questions about this workflow
What information does the lookup return?
Alchemy's NFT contract metadata action can return collection details such as name, symbol, total supply, token type, deployer, deployed block, marketplace metadata, and verification status.
Will this work if the shared file has no contract address?
The instruction should ask Notis to report that the address is missing. It cannot retrieve contract metadata without an address.
Does this automation grant or change Drive permissions?
No. The trigger reacts to new sharing permissions. The described action looks up NFT contract metadata in Alchemy.

Get NFT Contract Metadata

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.
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
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.
File Created
Triggers when a new file is created in Google Drive.
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.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
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.
File Shared (Permissions Added)

Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
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.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
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.
