Onboard an existing Entity with a Banking Connectivity provider.

Onboarding types

ONE_STEP: Submit all information, compliance declarations, risk assessment, and documents at once. The provider processes immediately.
PREVIOUSLY_ONBOARDED: Generate an internal Yuno onboarding ID without contacting the provider. Use when the entity was already onboarded externally.

For ONE_STEP, include compliance_declaration, risk_assessment, source_of_funds, and documentation. See Documentation types for the full list of supported document types.

Monitor progress via Get Entity Onboarding Status or webhook events. See Onboarding statuses for the full status lifecycle.
