I'm integrating a Vietnam API into my app.

API: MoMo ~ e-wallet payment platform API
Provider: MoMo (M_Service)
Auth: requires an API key (sign up: https://developers.momo.vn/v3/)
Pricing: freemium
Base URL: https://payment.momo.vn
Important note: Public EN+VI docs with a public test environment (test-payment.momo.vn); requests signed HMAC-SHA256 with partnerCode/accessKey/secretKey. Production keys only after merchant onboarding with business registration. VN-first.

Source: MoMo (M_Service) (https://developers.momo.vn/v3/)
Source type: Provider API or developer docs
Endpoint type: Provider API base URL
Integration difficulty: Needs API key
Last checked: 2026-07-03
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
