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 membership or access from a document means finding both the right wallet and collection before checking ownership.
- Extract both wallet and collection details from a parse.
- Check collection ownership with a focused Alchemy action.
- Return a clear result for follow-up or review.
Setup
Build it in a few focused steps.
- 1Connect Airparser and Alchemy once in Notis.
- 2Create an automation in Notis by describing the result you want.
- 3In one instruction, ask Notis to extract the wallet address and NFT collection contract from each submitted parse, check ownership through Alchemy, and report the result.
- 4Choose the Notis webhook trigger and select where run reports should go.
- 5Test with one real record containing both a wallet and collection contract.
