Why Businesses Pick DV Connect for OTP
Verification traffic is different from marketing traffic, and we treat it that way
A late OTP is a lost signup. We keep verification traffic on routes that are provisioned separately from promotional campaigns, monitor delivery per operator, and fail over automatically when a route degrades, so your success rate stays flat during peak hours and festival traffic.
The service suits login and registration flows, payment and transaction confirmation, password resets, KYC journeys, delivery verification and any two factor authentication you run in your own application.
What Our Clients Say
Feedback from businesses, agencies and development teams using DV Connect
Excellent OTP delivery speed with stable API performance. Integration took an afternoon and messages land instantly without delays.
We moved our whole signup flow across and the drop-off at the OTP step fell noticeably. Support answered on WhatsApp within minutes.
Reliable delivery, secure routing and pricing that actually works at our volume. Perfect for login verification.
The credits not expiring is what sold us. We buy in bulk when the rate is good and use them through the year.
Frequently Asked Questions
OTP delivery, API access, DLT rules and account setup
No. If you use our pre-approved OTP templates you can start sending immediately, with no DLT registration and no waiting period. DLT is only needed if you want your own custom OTP wording or your own sender ID.
Your API key is issued automatically within a couple of minutes of a successful payment and appears in your client area under the purchased service.
OTPs are sent over high priority verification routes and normally reach the handset within a few seconds. Delivery time beyond our gateway depends on the receiving operator.
Yes. OTP and verification traffic is transactional in nature, so it is delivered to DND registered numbers as permitted by TRAI regulations.
Without your own DLT registration, OTPs are delivered through our approved entities and templates, so the six character sender header may differ between messages. Register on DLT if you need a fixed brand header.
Yes, but custom content requires your own DLT entity registration and an approved template, as mandated by TRAI. Our team will guide you through the process at no extra charge.
No. OTP credits stay in your account until they are used. Buying another pack simply tops up the same API key.
We are not able to offer free OTP demos since the DLT mandate came into force. You can start with the smallest pack to test integration before committing to volume.
Failed messages are reported back through the API response and the delivery report, and undelivered credits are not deducted from your balance.
Yes. A plain HTTP API with JSON responses, sample code and delivery-report webhooks is available in your client area after purchase.
