Preparing developer boundaries before exposing merchant APIs

Oceafin’s MVP is web-first: Merchant Web, Admin Web, and the operator app carry the user experience. That does not mean the platform should ignore developer readiness.

The backend still needs clean internal boundaries for payment creation, idempotency keys, webhook ingestion, transaction events, merchant context, and audit trails. These boundaries are the foundation for future merchant API keys, signatures, rate limits, webhook subscriptions, and a developer portal.

Designing this early avoids a costly rewrite later. A future external API should expose a disciplined version of the platform’s existing operating model, not a rushed wrapper over raw channel calls.

For PSPs, developer readiness is also a trust signal. Merchants may start in a console, but larger operators will eventually ask how payment events, settlement status, and reconciliation data can connect to their own systems.
