Check the Addresszen key before VAT validation

Prevent address workflow failures by checking key readiness as soon as a VAT request arrives.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Key Availability

Tool to get public information on an api key, including whether it is currently usable. use when you need to verify that a key is valid and available before making further api requests.

Why this helps

A downstream address lookup can fail after a VAT check because the API key was unavailable.

  • Catch unusable credentials early
  • Reduce failed address requests
  • Keep VAT processing moving

Setup

Build it in a few focused steps.

  • 1Connect 44API and Addresszen in Notis once.
  • 2Create an automation named VAT key readiness.
  • 3Tell Notis to check Addresszen key availability for each incoming 44API VAT request and report the result.
  • 4Choose notis_webhook as the trigger and send the request payload to Notis.
  • 5Choose a report channel and test with one real VAT request.
