SMS & WhatsApp API for Transactional and OTP Messaging Across 800+ Schools
How a school CRM platform uses SMSGatewayCenter's SMS and WhatsApp APIs to power transactional and OTP messaging for more than 800 schools from a single integration.
This client operates a school management CRM used by more than 800 schools across India. Rather than each school integrating messaging separately, the CRM connects once to SMSGatewayCenter's SMS and WhatsApp APIs, and every connected school sends transactional and OTP messages through that shared integration.
The Solution
SMS API and WhatsApp API through SMSGatewayCenter
SMS API
The CRM uses SMSGatewayCenter's SMS API for OTP verification, fee reminders, attendance alerts, and other transactional messages triggered directly from the platform.
WhatsApp API
Alongside SMS, the CRM uses SMSGatewayCenter's WhatsApp API so schools can reach parents and staff with richer, two-way communication where preferred.
One Integration, Hundreds of Schools
800+ schools on one platform
A single API integration serves every school on the CRM, each sending transactional and OTP messages under its own account.
Secure OTP delivery
Login and verification OTPs reach parents and staff reliably, a critical dependency for a platform used at this scale.
DLT-compliant at scale
Transactional and OTP routing stays within TRAI DLT requirements across every connected school on the platform.

Frequently Asked Questions
A school management CRM integrates SMSGatewayCenter's SMS and WhatsApp APIs directly into its platform, so every connected school can trigger transactional and OTP messages, such as login verification, fee alerts, and attendance notifications, without building its own messaging infrastructure.
The CRM platform integrates once with SMSGatewayCenter's API, and that single integration serves every school on the platform, currently more than 800, each sending transactional and OTP messages to its own students, parents, and staff under the CRM's account.
When one API integration serves hundreds of schools at once, delivery delays or downtime affect every connected institution simultaneously, so consistent, DLT-compliant delivery at scale is essential rather than optional.
