This API is used to initiate a business payment transaction. It extends the standard transaction creation flow with additional parameters required for commercial or institutional payment scenarios. Supported Business Transaction Types The following business-to-entity payment flows are supported: B2B (Business-to-Business): Payments between two registered businesses or legal entities. B2C (Business-to-Consumer): Payments from a business to an individual (e.g., refunds, payouts, commissions). C2B (Consumer-to-Business): Payments from an individual to a business (e.g., invoice payments, service fees). 💡 Note: "Business Vertical Types" refer to the industry or use case context (e.g., e-commerce, education, travel, payroll), which may influence compliance, routing, or validation rules—but are distinct from transaction flow types above.
