Tier 1 · Recommended

Hosted Payment Links (Tier 1)

Create a hosted checkout page from your dashboard. Embed the link or button in your website, MVP, or application — Starterpay manages the payment UI, operator prompt, and redirects. Zero RCCM/NIU required.

Tier 2 · Registered Business

Direct REST API (Tier 2)

Programmatic server-to-server calls (POST /api/v1/pay) with direct Mobile Money debit and custom webhooks. Available to all developers in Sandbox; Live production requires Tier 2 business registration (RCCM/NIU).
