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 Tirunelveli business through the one-time DLT registration at no charge.
How fast are OTP messages delivered to Tirunelveli 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.
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 Tirunelveli application always knows which messages were delivered, when, and on which operator.
What uptime can my Tirunelveli business expect from the API?
We maintain 99.9% API availability with redundant infrastructure and 230+ operator routes behind it. Status alerts and 24x7 engineering support mean the rare incident is communicated and contained before it hurts your traffic.
Does the API support Unicode and regional languages?
Yes. Send messages in any Indian language by passing Unicode content — useful when your Tirunelveli 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 Tirunelveli marketing team can also use the web panel on the same credits.
