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 one collection relationship can take longer than the answer should.

  • Check whether a wallet owns any token from a specified collection.
  • Avoid retrieving a full wallet inventory for a simple question.
  • Use a direct request for ownership verification.

Setup

Build it in a few focused steps.

  • 1Connect Agenty and Alchemy once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and name it.
  • 3Tell Notis to check the wallet address and collection contract included in each request.
  • 4Pick the webhook trigger and choose where run reports go.
  • 5Test with a real wallet and collection you are authorized to check.
