NextPay API
NextPay API is the partner-facing surface for money movement work I have been building at NextPay.
The shipped surface covers collection and payout primitives, provider callbacks, integration contracts, and operational safety around high-trust payment flows.
Where public proof is limited by product and partner context, the story should stay focused on the shipped contract shape, operational boundaries, and integration responsibilities that can be described safely.
