Take wallet balance snapshots on demand
Send an address from your own intake or alert system and receive a current token balance report.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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
External alerts often stop at notification and leave the actual wallet check for later.
- Connect existing alerts to blockchain data
- Get balances without manual copying
- Create a reusable verification endpoint
Setup
Build it in a few focused steps.
- 1Connect Alchemy in Notis once.
- 2Create an automation and describe that it should read the wallet address from the webhook and retrieve ERC20 balances.
- 3Choose a Notis webhook as the trigger.
- 4Choose where run reports should go and copy the generated webhook endpoint.
- 5Test it with one real webhook payload containing an Ethereum address.
Questions about this workflow
Where does the address come from?
The webhook payload must provide the address or a clear instruction for Notis to use it.
Can the report be sent to a team channel?
Yes. Choose the connected report destination during automation setup.

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.
New Document Created
Triggers when a new Google Doc is created. This trigger monitors Google Docs and fires when new documents are detected. Uses timestamp filtering to efficiently poll for new documents.
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.
Document Deleted
Triggers when an existing Google Doc is deleted (moved to trash). This trigger monitors Google Docs and fires when documents are trashed.
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.
Document Placeholder Filled
Triggers when a Google Doc's plain text changes such that a configured placeholder token/pattern is no longer present (i.e., the document has been filled in). This trigger monitors a specific Google Doc and fires when a placeholder pattern that was previously present is no longer found in the document's plain text.
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.
Document Search Update
Triggers when a Google Doc matching a user-defined search query is newly created or updated since the last poll. This trigger uses timestamp filtering to efficiently monitor documents.
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.
Document Structure Changed
Triggers when a Google Doc's structure changes (headers/footers added/removed, tables/images count changes). This trigger monitors a specific document for structural changes like: - Headers added or removed - Footers added or removed - Tables added or removed - Images (inline objects) added or removed - Positioned objects added or removed - Footnotes added or removed
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.
Document Updated
Triggers when an existing Google Doc is updated or modified. This trigger monitors Google Docs and fires when documents are updated.
