Notis

Verify collection ownership during contact research

Provide a wallet and collection contract in a request to get a focused ownership check without retrieving a full portfolio.

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

A simple ownership question can lead to unnecessary browsing through full wallet holdings.

  • Check whether an address owns any token from a specified collection.
  • Use a direct ownership result for a focused research question.
  • Avoid requesting a full NFT portfolio when only one collection matters.

Setup

Build it in a few focused steps.

  • 1Connect Affinity and Alchemy once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and name it for collection ownership checks.
  • 3Tell Notis to check whether the wallet address in each request owns a token from the specified collection contract and report the result with the supplied context.
  • 4Pick the webhook trigger and choose where run reports go.
  • 5Test with one wallet and collection contract you are authorized to check.

Questions about this workflow

What details should I include?

Include the wallet address and NFT collection contract address in the request.

Does the check retrieve every NFT in the wallet?

No. It checks ownership for the specified collection, which keeps the result focused.
