Important: A submitted status means documents are under manual review. The wallet is not verified until status becomes completed.
Verification Levels: The verify endpoint returns verified status for wallets that were verified at your organization’s current verification level. If you upgrade your verification level, previously verified wallets will need to re-verify. Wallets verified through other organizations at the same scrutiny level will also appear as verified.
