Use the dashboard when code is not the right tool

Connect onboarding and recurring verification to the same normalized data. Keep human review for mismatches, adverse results, missing fields, and consequential decisions.

One account for dashboard and API access.
Consistent multi-jurisdiction response fields.
Source authority and freshness context.
