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
Confirming collection membership can take several manual steps when the address and contract come from separate references.
- Identify wallet and collection references from a page
- Check collection ownership without loading a full portfolio
- Keep the source and result together for review
Setup
Build it in a few focused steps.
- 1Connect Agentql and Alchemy once in the Notis portal.
- 2Create an automation and instruct Notis to extract a wallet address and collection contract from the supplied page.
- 3Choose a Notis webhook trigger for each ownership check.
- 4Choose where run reports should go, then test with a known wallet and collection.
Questions about this workflow
Does this return the exact NFT tokens held?
No. This action checks whether a wallet owns any token from the specified collection.
Can it check an entire article's addresses automatically?
The prompt can ask Agentql to identify relevant addresses, but it should clearly define which wallet and collection pair to evaluate.
