Verify collection ownership with one request
Check a wallet against a collection when access or eligibility questions come up, then get the result in Notis.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Check Collection Ownership
Checks whether a wallet owns any token from an NFT collection.
Why this helps
Verifying collection ownership manually adds friction to access checks and eligibility reviews.
- Check for ownership of any token from a specified collection.
- Support ERC721 and ERC1155 collection checks.
- Get a focused result without retrieving a full holdings list.
Setup
Build it in a few focused steps.
- 1Connect Addressfinder and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it Collection Ownership Check.
- 3Tell Notis to check whether each supplied wallet address owns any token from the specified NFT collection and report the result.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with a wallet and collection whose ownership status you can verify.
Questions about this workflow
Does this return every NFT the wallet owns?
No. It checks for ownership of a specified collection. Use a holdings action to retrieve a broader NFT list.
Can it check ERC1155 collections?
Yes. The action description says it supports ERC721 and ERC1155.
