A clean, well-documented SMS API with SDKs, SMPP and webhooks so developers ship messaging in hours, not weeks.
The icpaas.ai SMS API gives developers a straightforward way to send transactional, promotional and OTP messages directly from any application. With a simple REST interface, predictable JSON responses and ready-made SDKs for Node.js, Python, Java, PHP and Go, you can integrate reliable Indian SMS delivery into your stack and go live in a single afternoon.
Built by a TRAI/DLT-registered provider serving India since 2015, the API handles entity, header and template registration, DND scrubbing and consent management for you. Direct operator connectivity drives high delivery and roughly 2-5 second OTP latency, while SMPP v3.4 support, delivery webhooks and campaign analytics give serious teams the throughput and visibility they need at scale.
