5-Minute Integration

From signup to first production SMS:

1.Sign up free at /signup — no credit card.
2.Get free test credits — instantly available in dashboard.
3.Approve sender ID + DLT template — we submit, typically 24-48 hours.
4.Get your API key — copy from dashboard.
5.Make your first API call — use a code sample below.
6.Move to production — same endpoint, same key, no code change.

Send Your First SMS

Replace <SMS_SERVICE_URL> with your SMS service URL, shared after sign-up, and YOUR_API_KEY with the key from your dashboard. Send a form-encoded POST from your server (never from browser or app code); the message must match a DLT-approved template.

cURL

curl -X POST "<SMS_SERVICE_URL>/api/web/send/" \ --data-urlencode "apikey=YOUR_API_KEY" \ --data-urlencode "sender=SEDEMO" \ --data-urlencode "to=9900XXXXXX" \ --data-urlencode "message=Hello from SpringEdge" \ --data-urlencode "format=json"

Node.js

// Node.js 18+ (built-in fetch), run as an ES module const body = new URLSearchParams({ apikey: 'YOUR_API_KEY', sender: 'SEDEMO', to: '9900XXXXXX', message: 'Hello from SpringEdge', format: 'json' }); const res = await fetch('<SMS_SERVICE_URL>/api/web/send/', { method: 'POST', body }); console.log(await res.text());

Python

import requests data = { 'apikey': 'YOUR_API_KEY', 'sender': 'SEDEMO', 'to': '9900XXXXXX', 'message': 'Hello from SpringEdge', 'format': 'json', } res = requests.post('<SMS_SERVICE_URL>/api/web/send/', data=data, timeout=10) print(res.text)

A successful request returns {"groupID": 61, "MessageIDs": "61-1", "status": "AWAITED-DLR"}. For delivery report callbacks, message status, credit balance, and error messages, see the SpringEdge SMS API documentation. Node.js users can also use the official springedge npm package.

DLT Compliance Without the Pain

Every commercial SMS in India must use a TRAI DLT-registered entity, an approved sender ID (header), and a pre-scrubbed template. For most startups this is a 1-2 week process if done in-house: register on each operator's DLT portal, get sender IDs approved across all four, submit templates and wait for scrubbing.

SpringEdge handles all three steps for you. You provide draft templates — we submit on Jio, Airtel, Vi, and BSNL portals and shepherd them through approval. Typical end-to-end time: 24-48 hours. See our DLT information guide for the full picture.

Test credits at signup are sufficient to send 25-50 test SMS, 5-10 OTP flows, or 10-20 WhatsApp template messages. Enough to verify your end-to-end integration without paying.

DLT entity registration on the operator portals has a one-time fee paid to the operator (typically ₹5,000-7,000 total). Sender ID and template approvals are free of charge. SpringEdge handles the submission process at no additional cost.

5-15 minutes to send your first test SMS. 1-2 days to wire up production flows (delivery webhooks, retry logic, error handling). Add 24-48 hours for DLT template approval if you don't already have one.

No on both. Pay-as-you-go with no monthly minimum and no contract; the minimum purchase is 25,000 credits per top-up. Stop sending any time. Credits don't expire while your account is active.

Yes — free test credits work against the same production endpoints, so test code works unchanged in production. No separate sandbox URL or sandbox-only API key.

Up to 10 requests per second per IP address. We don't throttle based on monthly volume, only per-second rate. For higher volumes, talk to our team.

Yes — the standard pattern is a 6-character alpha sender ID matching your brand (e.g. SPEDGE, ZOHOIN). Approval typically takes 2-4 business days across all four operators. Your sender ID becomes exclusive to your account on each operator's DLT.

Failed SMS (operator delivery failure, invalid number, blacklisted recipient) are automatically credited back to your wallet within 24 hours. Successful sends are not refundable. Wallet top-ups are not refundable but credits can be used for any service (SMS, WhatsApp, Voice).

Yes — most SMS API integrations are a config change (new endpoint, new key). DLT approvals don't transfer between providers; we re-submit equivalents in parallel so you keep sending throughout the switch. See Twilio alternatives in India for migration tips.
