Turn a collection contract discovered while browsing into a holder overview for research and planning.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Owners for Collection
Lists owner addresses for an NFT collection, with optional token balances.
Why this helps
Understanding holder distribution takes time when owner information must be collected one result at a time.
- Retrieve owner addresses for a specified collection contract.
- Include token balances per owner when the action returns them.
Setup
Build it in a few focused steps.
- 1Connect Airtop and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis to create it in plain language.
- 3Describe the outcome: retrieve owners for the NFT collection contract supplied by my Airtop workflow and summarize ownership distribution and any returned token balances.
- 4Pick the webhook trigger and choose where run reports go.
- 5Test with a collection contract whose ownership you can verify.
