For more endpoints (bulk send, scheduling, delivery reports, OTP verify) see the SpringEdge API documentation.

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.

Frequently Asked Questions

Starts at ₹0.18 per SMS for low-volume startups (Starter tier). Drops to ₹0.12 at high volume. Volume discounts apply automatically — no negotiation required. See /pricing for current rates.

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, no minimums, no contract length. Stop sending any time. Wallet credits don't expire for 12 months.

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.

100 requests/second per API key with burst to 200/second. Higher limits available on request for enterprise accounts. We don't throttle based on monthly volume, only per-second rate.

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.
