Daily API Calls

Quick start

A modern RESTful API

Our REST API follows industry best practices with predictable resource-oriented URLs, JSON-encoded request and response bodies, and standard HTTP methods.

01

Get an API key

Generate a key from your dashboard — test and live keys are kept separate.

02

Make your first call

Send a request with your key as a Bearer token. Pick cURL, JavaScript or Python.

03

Listen for events

Register a webhook endpoint to hear about paid invoices, new customers and low stock.

Authentication

Security & real-time events

API Keys

Generate API keys from your dashboard. Include your key in theAuthorizationheader as a Bearer token. Ideal for server-side integrations.

OAuth 2.0

Use the authorization code flow for user-facing apps. Users authorize your app to access their KornexAI data securely with scoped permissions and refreshable tokens.

Webhooks

Hear about every change, the moment it happens

Subscribe to the events you care about and we’ll deliver signed JSON payloads to your endpoint — with retries when it’s down.
