Key Takeaways
- node.js android sms gateway api send sms: use server-side fetch/axios against documented HTTPS JSON — not a branded npm “SMS SDK” product from us.
- Accept ≠ deliver; wire DLR or webhooks.
- AbortSignal / timeouts belong on every outbound call.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. BYO Android and operator airtime.
- Keep OTP lanes off marketing blast loops.
- Free is 300 SMS lifetime; paid from $19/month.
fetch/axios — not an npm SMS SDK SKU
Search intent for node.js android sms gateway api send sms is a production HTTP client, not a marketplace package theatre. Service pricing is based on device count and total SMS sent through the gateway. Start from Android SMS Gateway API and confirm fields in Developer Center.
Shipping `sms-gateway-sdk` on npm that only wraps one POST is fine as your private module — it is not a first-party product line from us, and it still spends your SIM airtime.
Send flow in Node.js
Server process loads the Bearer from env, POSTs JSON, stores the accepted id, and correlates webhooks. Conceptual sketch — confirm live schema before production.
const res = await fetch(process.env.SMS_GATEWAY_SEND_URL, {
method: 'POST',
headers: {
Authorization: `Bearer ${process.env.SMS_GATEWAY_API_KEY}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({ to: e164, text: body, client_ref: challengeId }),
signal: AbortSignal.timeout(15_000),
});
Node path vs aggregator SDK habits
| Habit | Aggregator SDK | Android SIM gateway |
|---|---|---|
| Client library | Vendor SDK package | Thin HTTPS client you own |
| From number | Rented cloud number | Your SIM MSISDN |
| Cost model | Per-message + number rent | Devices + send volume + carrier airtime |
| Last mile | Aggregator SMSC | Paired Android radio |
Timeouts and offline devices
Abort hung sockets. Alert on device last-seen and Pending age — queues accept work the radio cannot send. Sibling bulk patterns: Node bulk send loop.
Server-only secrets
Never embed keys in Next.js client bundles or React Native. Rotate after staff changes. Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Adjacent features: two-way SMS.
Node send checklist
- REST client only — no official npm SDK expectation.
- Env Bearer + AbortSignal timeout.
- Persist id; verify DLR/webhook.
- OTP separate from marketing concurrency.
- BYO Android + operator credit.
