Node.js examples

All examples use the Inzi REST API directly. No SDK package required.

Create checkout (fetch)

const res = await fetch('https://api.inzilink.com/api/v1/checkouts', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.INZI_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    amount: '25.00',
    currency: 'USD',
    metadata: { order_id: 'ORD-123' },
    redirect_url: 'https://yoursite.com/success',
    webhook_url: 'https://yoursite.com/webhooks/inzi',
  }),
})
 
const { checkout_url, id } = await res.json()

Create checkout (axios)

import axios from 'axios'
 
const { data } = await axios.post(
  'https://api.inzilink.com/api/v1/checkouts',
  {
    amount: '25.00',
    currency: 'USD',
    metadata: { order_id: 'ORD-123' },
    redirect_url: 'https://yoursite.com/success',
  },
  {
    headers: { Authorization: `Bearer ${process.env.INZI_API_KEY}` },
  },
)
 
const { checkout_url } = data

Get checkout status

const res = await fetch(
  `https://api.inzilink.com/api/v1/checkouts/${checkoutId}`,
  { headers: { Authorization: `Bearer ${process.env.INZI_API_KEY}` } },
)
const checkout = await res.json()
console.log(checkout.status) // pending | completed | expired

Verify webhook signature

import crypto from 'crypto'
 
function verifyInziWebhook(rawBody, headers, secret) {
  const timestamp = headers['x-inzi-timestamp']
  const signature = headers['x-inzi-signature'].replace('sha256=', '')
 
  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${timestamp}.${rawBody}`)
    .digest('hex')
 
  return crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(signature))
}

List checkouts with pagination

const params = new URLSearchParams({
  status: 'completed',
  limit: '20',
  offset: '0',
})
 
const res = await fetch(
  `https://api.inzilink.com/api/v1/checkouts?${params}`,
  { headers: { Authorization: `Bearer ${process.env.INZI_API_KEY}` } },
)
const { data, total } = await res.json()
