I'm integrating a Vietnam API into my app.

Provider: SpeedSMS
Auth: requires an access token (sign up: https://speedsms.vn/sms-api/)
Pricing: paid
Base URL: https://api.speedsms.vn/index.php
Important note: Register at connect.speedsms.vn to get an access token, used as the username in HTTP Basic auth. Pay-per-message; SDKs and code samples for most languages. Docs Vietnamese-first. VN-first.

Source: SpeedSMS (https://speedsms.vn/sms-api/)

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.
