One Communication Platform. Every Business Alert.
Alert21 is being built as the communication layer your application can rely on — from India’s DLT-ready SMS requirements to future multi-channel notification workflows.
A Communication Layer Between Your Product and Your Customer
Instead of integrating separate vendors for every alert channel, Alert21 is designed to provide a consistent API and event model. Your application submits a message or business event; Alert21 validates policy, selects the configured route, queues delivery, normalizes provider responses and returns a consistent status.
Core Platform Capabilities
- API keys and secure authentication.
- Template and sender mapping.
- Queue-based message processing.
- Provider adapters and route switching.
- Delivery receipts and normalized message states.
- Signed webhooks.
- Rate limiting and abuse protection.
- Usage metering and billing.
- Audit logs.
- Country- and channel-ready capability registry.
A Stable API Even When Providers Change
Provider details should remain an Alert21 implementation concern. Customers integrate with Alert21 while routing, provider credentials and provider-specific payloads remain behind the platform boundary.
Customer benefit: if Alert21 changes or adds an upstream provider, the customer integration should not need to change.
Designed for India. Architected for International Scale.
India messaging begins with DLT-aware SMS. International expansion should add country-specific sender rules, route availability, consent requirements, pricing and provider adapters without changing the core customer API model.
From Message API to Event API
As Alert21 evolves, applications should be able to send a business event — such as payment.success or order.shipped — and let configured workflows determine the best communication channels.
