Can you obtain a payment-provider account for us?
Provider approval and onboarding remain subject to the provider’s eligibility and verification requirements. Integration support does not guarantee account approval.
Do you support subscriptions or split payments?
These can be discussed where the provider and business model support them. Availability, permissions, settlement rules and implementation scope must be confirmed first.
