How to enrich transactions without sending PII.
Only send one descriptor and optional non-sensitive context. Keep full statements and customer-identifying data out of enrichment workflows.
| Allowed | Rejected |
|---|---|
| Single merchant descriptor, amount, currency, country, date, MCC | Card numbers, account numbers, bank credentials, full statements |
| Normalized signature, processor hint, confidence band | Emails, phone numbers, addresses, customer names |
