Check NFT collection ownership after location validation
Combine a validated user location with a targeted NFT ownership check for access or eligibility reviews.
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
Location and token eligibility often live in separate tools, leaving a founder to repeat the same review by hand.
- Check a specific collection against the wallet in an Addresszen request.
- Keep location validation and eligibility review in one automation run.
- Reduce repetitive lookups when screening access requests.
Setup
Build it in a few focused steps.
- 1Connect Addresszen and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, ask Notis to check whether the request's wallet owns a token from the NFT collection you specify and summarize the result.
- 4Pick the notis_webhook trigger and choose where run reports should go.
- 5Test with one real request, wallet address, and collection contract address.
