Run phone due diligence on a 21risk vendor signal

Trigger

Webhook received

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

Action

Get Phone Number Information

Why this helps

Vendor due diligence gets delayed when phone checks rely on ad hoc manual research.

  • Standardizes a vendor phone check
  • Adds carrier and complaint evidence
  • Keeps due diligence connected to the signal

  • 3Pick the 21risk webhook trigger and choose the due diligence report destination.
  • 4Test with one real vendor number.
