SMS API in Thoothukudi — FAQs

Does the API support Unicode and regional languages?

Yes. Send messages in any Indian language by passing Unicode content — useful when your Thoothukudi application serves customers who prefer reading in their own script. Long-message concatenation is handled automatically.

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 Thoothukudi marketing team can also use the web panel on the same credits.

How quickly can my Thoothukudi 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 Thoothukudi 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 Thoothukudi 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 Thoothukudi business through the one-time DLT registration at no charge.

How fast are OTP messages delivered to Thoothukudi numbers?

Our dedicated OTP route delivers in a few seconds to all Tamil Nadu 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.
