Sync NFT Inventory via Webhook Triggers
When external blockchain monitoring tools detect changes to your collection, Notis can receive a webhook and automatically catalog all NFTs to keep Linear in sync.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.

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.
Why this helps
You use external blockchain monitoring tools but they don't connect to Linear. NFT inventory changes happen without updating your project tracker.
- External blockchain tools can trigger NFT inventory updates via webhook
- Your Linear projects stay in sync with on-chain collection changes
- No manual updates needed when NFTs are minted or burned
- Multiple systems talk to each other through Notis
Setup
Build it in a few focused steps.
- 1Connect Notis to Linear and Alchemy via the portal.
- 2Ask Notis 'Give me a webhook URL for NFT inventory updates' and Notis will provide it.
- 3Configure your external blockchain tool to send webhooks to that URL when changes occur.
- 4Optionally set which contract address to query when webhooks arrive.
- 5Test by triggering a webhook from your external tool and verifying NFT inventory updates in Linear.
Questions about this workflow
What format should the webhook payload be?
Notis accepts simple JSON. The webhook just needs to specify the contract address or collection you want to catalog. Notis handles the rest.
Can I send webhooks from multiple external tools?
Yes, multiple tools can send to the same webhook URL. Notis queues and processes all updates.

Issue Created Trigger
Triggered when a new issue is created.
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.
Issue Updated Trigger
Triggered when an issue is updated. For example labels are changed, issue status is changed, etc.
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.
Private Team Comment Created
Fires when a new comment is posted on an issue in a private Linear team (polled with the connected user's token).
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.
Private Team Issue Created
Fires when a new issue appears in a private Linear team (polled with the connected user's token).
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.
Private Team Issue Properties Updated
Fires when properties on an issue change in a private Linear team (polled with the connected user's token).
