Pricing: paid
Base URL: https://rest.esms.vn
Important note: Self-serve signup; every call carries ApiKey + SecretKey. Pay per message; brandname SMS and Zalo ZNS templates require registration/approval. Docs Vietnamese-first. 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.
