Check wallet access to an NFT collection
When a follow-up depends on collection ownership, ask Alchemy for a direct ownership check.
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 by browsing holdings manually adds avoidable steps to a follow-up.
- Check if a wallet owns any token from a specified collection.
- Use a focused check instead of retrieving a full portfolio.
- Support ERC-721 and ERC-1155 ownership checks.

- 1Connect AimTell and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Describe the wallet and collection to check and how to report the result in one instruction.
- 4Pick the webhook trigger and choose where run reports go.
- 5Test with one real example using a wallet and collection you can query.
