We are a Payment Service Provider (PSP)/Payment Processor/Payment Gateway and have completed the Apple Pay integration and successfully tested transactions in the Sandbox environment. We are now planning to move the integration to Production and would like to understand the prerequisites, certification requirements and process involved in enabling Apple Pay for our merchants. Could you please clarify the following: Production Enablement: What are the mandatory prerequisites for a PSP/Payment Processor/Payment Gateway to move from Sandbox to Production? Certification: Is formal certification or approval from Apple required for the Payment Processor before Go-Live? Certificates: Are separate Production Payment Processing and Merchant Identity Certificates required? Merchant Onboarding: What is the process for onboarding and enabling individual merchants under our PSP/Payment Processor setup? Any provisions for Bulk On-boarding? Testing & Validation: Are there any mandatory test scenarios or validations required before Production enablement? Production Access: What approvals, configurations or access enablements are required from Apple's end? Go-Live Process: What is the recommended sequence of activities and expected timeline for Production activation?
