Communication Services
SMS, WhatsApp, and Email APIs — integrate real-time messaging directly into your applications and automate the communications your business depends on.
Why Communication APIs
Whether you're sending order confirmations, OTPs, appointment reminders, or bulk promotional messages — Sahyadri integrates messaging APIs directly into your existing or new application. One integration, every channel.
SMS reaches customers even without internet. We integrate transactional and promotional SMS into your application — OTPs, alerts, booking confirmations, delivery updates, and bulk campaigns.
We also support two-way shortcode integration — letting customers reply, opt in, or interact with your service via SMS, with responses captured and processed in your system.

WhatsApp is where your customers already are. We integrate the official WhatsApp Business API into your application — enabling automated notifications, two-way conversations, rich media messages, and interactive reply buttons.
Ideal for appointment reminders, order tracking, customer support workflows, and promotional campaigns — all running through one familiar interface your customers trust.
Email remains the highest-ROI communication channel for business. We integrate transactional and marketing email APIs into your applications — reliably delivering welcome emails, invoices, reports, newsletters, and campaigns straight from your system.
