SAP integration shouldn’t be this hard

Connecting to SAP S/4HANA typically means weeks of setup, complex authentication flows, and fighting with OData quirks. S4Kit changes that. 
// The traditional way: 50+ lines of boilerplate
import axios from 'axios';

// Step 1: Get CSRF token
const tokenResponse = await axios.get(
  'https://sap-server.company.com/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartner',
  {
    headers: {
      'Authorization': `Basic ${Buffer.from(`${user}:${pass}`).toString('base64')}`,
      'x-csrf-token': 'Fetch',
      'sap-client': '100',
    }
  }
);
const csrfToken = tokenResponse.headers['x-csrf-token'];
const cookies = tokenResponse.headers['set-cookie'];

// Step 2: Make the actual request
const response = await axios.get(
  'https://sap-server.company.com/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartner',
  {
    params: {
      '$select': 'BusinessPartner,BusinessPartnerName',
      '$filter': "BusinessPartnerCategory eq '1'",
      '$top': 10
    },
    headers: {
      'Authorization': `Basic ${Buffer.from(`${user}:${pass}`).toString('base64')}`,
      'x-csrf-token': csrfToken,
      'Cookie': cookies.join('; '),
      'sap-client': '100',
      'Accept': 'application/json',
    }
  }
);

// Step 3: Parse the weird OData response format
const partners = response.data.d.results;

Built for developers who value their time

5-Minute Setup

Install the SDK, add your API key, start querying SAP. No SAP expertise required.

Type-Safe

Full TypeScript support. Generate types from your SAP metadata. Catch errors at compile time.

Stripe-like DX

Simple API keys instead of certificates. Clear error messages. Predictable behavior.

Multi-Environment

Sandbox → Dev → QA → Production. Same code, different connection string.

Observable

Every request logged. Performance metrics. Error tracking. Full audit trail.

Secure by Design

Encrypted credentials. Granular permissions. Full audit trails.

​
How it works

You call the SDK

Your app uses the S4Kit SDK with a simple API key. No SAP credentials in your code.
await client.A_SalesOrder.list({ top: 10 })

We handle the complexity

S4Kit authenticates to SAP, manages tokens, handles CSRF, retries on failure.

SAP responds

Your SAP system processes the request and returns data through our secure proxy.

You get clean JSON

No OData wrapper objects. No d.results. Just the data you asked for.

​
Everything you need

Create, read, update, and delete any SAP entity. Batch operations. Deep inserts. Navigation properties.
// Create
const order = await client.A_SalesOrder.create({ ... });

// Read
const orders = await client.A_SalesOrder.list({ top: 100 });

// Update
await client.A_SalesOrder.update(orderId, { Status: 'C' });

// Delete
await client.A_SalesOrder.delete(orderId);
Full OData query support with a clean API. Filter, sort, paginate, expand relations.
const orders = await client.A_SalesOrder.list({
  select: ['SalesOrder', 'TotalNetAmount', 'SoldToParty'],
  filter: "CreationDate ge 2024-01-01 and TotalNetAmount gt 10000",
  orderBy: 'CreationDate desc',
  expand: ['to_Item', 'to_Partner'],
  top: 50
});
Generate TypeScript types from your SAP OData metadata. Full autocomplete in your IDE.
npx s4kit generate-types --api-key sk_live_... --output ./types
Control exactly which entities and operations each API key can access.
production:
  API_BUSINESS_PARTNER:
    A_BusinessPartner: [list, get]
    A_BusinessPartnerAddress: [list, get]
  API_SALES_ORDER_SRV:
    A_SalesOrder: [list, get, create, update]
