Overview - Corsair

Use NetSuite through Corsair: one client, typed API calls, local DB sync. What you get:

84 typed API operations
13 synced entities (customerPayments, customers, employees, invoices, itemFulfillments, itemReceipts, and 7 more) for fast .search() / .list()

Setup

Install

npm install corsair @corsair-dev/netsuite

yarn add corsair @corsair-dev/netsuite

pnpm install corsair @corsair-dev/netsuite

bun add corsair @corsair-dev/netsuite

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { netsuite } from '@corsair-dev/netsuite';

export const corsair = createCorsair({
	plugins: [
		netsuite({
			accountId: 'TSTDRV123',
		}),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

With multiTenancy: true, scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

OAuth 2.0 (Recommended)

Open hub.corsair.dev, navigate to your project, and enter the client ID and client secret from your NetSuite OAuth app.NetSuite needs your account ID to build account-specific REST and OAuth URLs.

netsuite({
	accountId: 'TSTDRV123',
})

More: OAuth 2.0

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'netsuite',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

List customer records

const tenant = corsair.withTenant('acme');
await tenant.netsuite.api.records.listRecords({ recordType: 'customer', limit: 10 });

Create a customer

const tenant = corsair.withTenant('acme');
await tenant.netsuite.api.customers.createCustomer({
	body: {
		entityId: 'ACME',
		companyName: 'Acme Inc.',
		isPerson: false,
		subsidiary: { id: '1' },
	},
});

See the full list on the API page.

Synced entities support tenant.netsuite.db.<entity>.search() and .list(): customerPayments, customers, employees, invoices, itemFulfillments, itemReceipts, items, journalEntries, purchaseOrders, salesOrders, vendorBills, vendorPayments, vendors. See Database for filters and operators.
