Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Check NFT Holder Status
Checks whether a wallet holds any NFTs from a contract.
Why this helps
Verifying NFT ownership by hand can delay an access or membership decision tied to a device event.
- Check holder status for a supplied wallet and contract.
- Return a focused ownership result for review.
- Use an IoT event to start the check.
Setup
Build it in a few focused steps.
- 1Connect Adafruit IO and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3Ask Notis to check whether the supplied wallet holds an NFT from the supplied contract and summarize the result.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real example containing a wallet address and contract address.
