Public API

Build on OneHub360

A REST API that doesn't require an enterprise budget. Deploy integrations in hours, not months, with a modern JSON API plus webhooks that keep your stack in sync near real time.

Every plan comes with API keys, generous rate limits, and the documentation you need to start shipping automations, dashboards, and workflows without waiting for a partner.

Connect Everything

REST API for contacts, deals, tasks, appointments, invoices

Real-Time Webhooks

9 event types, HMAC signed, automatic retry for fire-and-forget integrations

Simple Auth

API keys, no OAuth complexity, instant setup and permission scoping

Code examples

One snippet covers a curl request and a JS fetch you can drop straight into your app.

curl https://api.onehub360.com/v1/contacts   -H 'Authorization: Bearer YOUR_API_KEY'   -H 'Accept: application/json'

const response = await fetch('https://api.onehub360.com/v1/contacts', {
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Accept': 'application/json',
  },
})
const data = await response.json()
