ISP API Integration — Connect NowaCRM with Your Tech Stack

Reviewed by the NowaCRM ISP operations team Last updated: May 18, 2026

Quick answer

No ISP platform works in isolation. You need to connect with payment gateways, SMS providers, accounting software, network monitoring tools, and custom applications. NowaCRM provides comprehensive REST APIs for every major function — subscriber management, billing, payments, and network operations.

01

Subscriber Management API

Create, read, update, and search subscribers programmatically. The API supports full subscriber lifecycle management including plan assignment, status changes, and KYC updates. Use webhooks to receive real-time notifications when subscriber events occur — activation, suspension, plan change.

02

Billing & Payment API

Generate invoices, record payments, manage wallets, and query billing status via API. Integrate with external accounting software (Tally, QuickBooks) for financial sync. Payment gateway webhooks are already built-in for Razorpay and PhonePe — custom gateway integration uses the same webhook pattern.

03

RADIUS & Network API

The RADIUS API is the backbone — FreeRADIUS calls it for live authentication and accounting. NAS management, IP pool configuration, and CoA operations are available via API. Network monitoring tools can pull session data and bandwidth metrics for integrated dashboards.

04

Webhook Events

Subscribe to webhook events for real-time notifications: subscriber.activated, invoice.generated, payment.received, ticket.created, and more. Webhooks enable event-driven integrations without polling. Each webhook includes full event payload and signature verification for security.

05

API Authentication & Security

API access uses token-based authentication with per-tenant API keys. Rate limiting prevents abuse. All API calls are logged in the audit trail. HTTPS encryption ensures data security in transit. API documentation with request/response examples is available in the platform.
