SMS service

Send any text — OTP, alerts, reminders, bulk — from a normal phone number.

Waaguan SMS is a separate product from MoMo payments. No sender ID registration — messages go out from a normal number. You write the message; we deliver it.

Quick start

Buy SMS credits (how credits work).
Generate an sk_sms_ key on Dashboard → SMS.
POST /api/v1/sms/send with { "to": "0244…", "message": "…" }.

Authentication

SMS uses Authorization: Bearer sk_sms_… — not your payment sk_live_ key. Create and revoke SMS keys on the SMS overview page.

API

Send SMS — POST /api/v1/sms/send
From numbers — GET /api/v1/sms/from
Message status — GET /api/v1/sms/:id

Dashboard

Under SMS you can:

Send — one number, bulk paste, or selected contacts
Credits — buy plans or custom top-ups with MoMo
Contacts — add or upload CSV (name,phone)
Templates — save messages; use {{name}} for personalization
History — pending, sent, delivered, failed
Send from — random (recommended) or a fixed number
