How long does OTP API integration take for a Coimbatore business?
About 15 minutes to first test code using our REST API and sample scripts; a production integration with delivery webhooks is usually same-day work. Our engineers assist your Coimbatore team directly during integration at no extra cost.
Is DLT registration needed for OTP messages in Coimbatore?
Yes — OTP templates must be registered on DLT like all commercial SMS in India. The process is straightforward for transactional templates and we complete it with you free of charge; most Coimbatore businesses are approved within days.
Can OTP SMS work alongside my promotional campaigns?
Yes, on one account — but on separate routes. OTPs ride the dedicated transactional lane while promotions use marketing routes, so a big Coimbatore campaign never delays a login code. Reporting stays unified in one dashboard.
What does OTP SMS cost in Coimbatore?
Per-message transactional rates with volume slabs — no setup fee, no rental, free sandbox. OTP volumes grow fast, so slabs matter: share your monthly code estimate and we will quote exact Coimbatore pricing immediately.
Do OTPs deliver on DND numbers in Coimbatore?
Yes. OTPs are transactional messages, which TRAI permits to DND-registered numbers. Your Coimbatore users receive verification codes regardless of their DND status — one reason the transactional route and proper DLT templates matter.
Can I monitor my OTP delivery performance?
In real time. The dashboard shows sent, delivered, failed and average delivery time, sliceable by hour and operator — so your Coimbatore team can verify our 98-99% transactional delivery claim against your own traffic, every day.
