Common Workflows

Basic Address Verification

1. POST /v3/poa/ → {"document": utility_bill}
2. If "Approved" → address verified
   If "Declined" → check warnings:
     EXPIRED_DOCUMENT → ask for a more recent document
     MISSING_ADDRESS_INFORMATION → ask for clearer image
     NAME_MISMATCH → verify identity matches

Full KYC with Address

1. POST /v3/id-verification/ → verify identity document
2. POST /v3/passive-liveness/ → verify real person
3. POST /v3/poa/ → verify address
4. System auto-matches name between ID and PoA documents
5. All Approved → identity + address verified
