Review ERC-20 token balances from a webhook
Send a wallet address to a Notis webhook and get a readable balance summary from Alchemy.
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
A wallet check can turn into a multi-step interruption when the address and results have to be handled manually.
- Start a balance lookup with an HTTP request.
- Summarize available ERC-20 balances for the supplied address.
- Use a specific token contract list when the request supplies one.
Setup
Build it in a few focused steps.
- 1Connect Alchemy once in Notis.
- 2Create an automation for on-demand wallet balance reviews.
- 3In one instruction, ask Notis to retrieve and summarize ERC-20 balances for the wallet address supplied with each request, using any supplied token contract list.
- 4Pick the webhook trigger and choose where run reports go.
- 5Test with one real request containing a wallet address.
Questions about this workflow
Can the webhook request limit the lookup to specific tokens?
Yes. The action supports either all tokens the address has interacted with or a specified set of token contract addresses.
Does it transfer tokens?
No. This workflow reads token balances; it does not send transactions.

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.

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.
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.
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.
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.
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.
