Webhook Integration

Subscribe to real-time event notifications delivered directly to your server the instant something happens — a new order, a lead capture, a client registration. Webhooks eliminate polling and let you build truly reactive, event-driven applications.

SDK Downloads

Skip the raw HTTP layer entirely. Our officially maintained SDKs for JavaScript/Node.js, Python, PHP, and Ruby wrap every endpoint in idiomatic, typed, well-documented functions. All SDKs are MIT licensed and actively maintained on GitHub.

API Overview

A clean, predictable REST API

The KVL TECH API follows RESTful conventions. Every resource is addressable by a URL, every operation maps to an HTTP verb, and every response is JSON. There are no surprises — what you read in these docs is exactly what you get in production.

Base URL

https://api.kvlbusinesssolutions.com/v1

Format

JSON (request & response)

Auth

Bearer token (JWT) in Authorization header

Rate Limits

1,000/hr free · 10,000/hr paid · Unlimited enterprise

Versioning

v1 (current) · v2 (beta)

example.js

// Fetch all products
const response = await fetch(
  'https://api.kvlbusinesssolutions.com/v1/products',
  {
    method: 'GET',
    headers: {
      'Authorization': 'Bearer YOUR_JWT_TOKEN',
      'Content-Type': 'application/json',
      'Accept': 'application/json',
    },
  }
);

const data = await response.json();
// { products: [...], total: 42, page: 1 }
console.log(data.products);

Replace YOUR_JWT_TOKEN with the token returned by POST /auth/token

Endpoints

Core API Endpoints

Every endpoint supports HTTPS only. All responses include a status code, a data object, and pagination metadata where applicable. Error responses follow RFC 7807 (Problem Details) so your error handling stays consistent.

Method	Endpoint	Description
GET	/products	List all products with optional filters, pagination, and sorting.
GET	/products/:id	Retrieve full details for a single product by its unique identifier.
POST	/orders	Create a new order, link it to a client, and trigger fulfillment workflows.
GET	/orders/:id	Fetch the current status, line items, and payment details of an order.
POST	/leads	Submit a new sales lead directly into the KVL CRM pipeline.
GET	/clients	Retrieve your full client list including contact info and account status.

SDKs

Official Client Libraries

Stop writing boilerplate HTTP code. Our officially maintained SDKs handle authentication, retries, rate-limit back-off, and response parsing so you can focus purely on building your product. Install in seconds, integrate in minutes.

JavaScript / Node.js

npm install kvltech-sdk

Python

pip install kvltech

PHP

composer require kvltech/sdk

Ruby

gem install kvltech

Webhooks

Real-time Event Notifications

Webhooks push events to your server the moment they occur — no polling required. Register an HTTPS endpoint in your developer dashboard and we will send a signed POST request containing a full JSON payload whenever a subscribed event fires. Every delivery is signed with HMAC-SHA256 so you can verify authenticity before processing.

order.created

Fired when a new order is placed.

order.paid

Fired when payment is confirmed.

lead.new

Fired when a new lead enters the CRM.

client.registered

Fired when a new client account is created.

Example Payload — order.created
