SMS API in Delhi — FAQs
Can the same API account send promotional campaigns too?
Yes. One account covers transactional, promotional and OTP routes, each with the correct sender ID type and time-window rules applied automatically. Your Delhi marketing team can also use the web panel on the same credits.
How quickly can my Delhi team integrate the SMS API?
Most developers send their first test message within 15 minutes using our sample code in PHP, Python, Java, Node.js or .NET. A production-ready integration with delivery webhooks typically takes a day. Our engineers are available throughout on call or WhatsApp.
What is the API pricing for a Delhi startup?
Pay per message with volume slabs and no monthly minimum or setup fee — a sandbox account for testing is free. Share your expected volumes and message types and we will quote exact rates for your Delhi project the same day.
Does the API handle DLT compliance automatically?
Largely, yes. Your approved DLT templates are mapped to IDs inside the API; requests validate against them before sending, and clear error codes flag mismatches instantly. We also assist your Delhi business through the one-time DLT registration at no charge.
How fast are OTP messages delivered to Delhi numbers?
Our dedicated OTP route delivers in a few seconds to all Delhi operators, with automatic re-routing if a route hiccups and optional voice-OTP fallback. That speed holds during login storms and festival traffic spikes alike.
Can I get delivery reports back into my application?
Yes. Webhooks push real-time delivery status to your endpoint, and a pull API lets you query message status anytime. Your Delhi application always knows which messages were delivered, when, and on which operator.
