Pricing: freemium
Base URL: https://openapi.zalopay.vn
Important note: Public docs in EN+VI with API Explorer and sandbox (sb-openapi.zalopay.vn); requests signed HMAC with app_id + key1, callbacks verified with key2. Production requires merchant onboarding. VN-first.

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.
