# Culqi Node SDK (TypeScript)

[![NPM Version](https://img.shields.io/npm/v/culqi-nodejs.svg)](https://www.npmjs.com/package/culqi-nodejs)

**Culqi, zero-runtime-dependency SDK** for integrating Culqi’s REST API in
Node.js projects.  
The library ships with **API v2** resources and is scaffolded to support future
versions side by side.

## Requirements

The SDK Supports NodeJS version 22 or higher.

## Quick start

```bash
npm install culqi-nodejs
```

```ts
import { CulqiClient } from 'culqi-nodejs';

const culqi = CulqiClient.init({
  publicKey: process.env.CULQI_PUBLIC_KEY!,
  secretKey: process.env.CULQI_SECRET_KEY!,
  apiVersion: '2',
});

const { id: tokenId } = await culqi.tokens.create({
  card_number: '4111111111111111',
  cvv: '123',
  expiration_month: '07',
  expiration_year: '2027',
  email: 'jane_doe@domain.com',
});

await culqi.charges.create({
  amount: 1000,
  currency_code: 'PEN',
  source_id: tokenId,
  email: 'jane_doe@domain.com',
});
```

## Versioning strategy

- **Code & Types are namespaced by API version** (`src/types/v2`, `src/resources/v2`).
- If Culqi ever ships an API v3, we’ll simply add new types and resources inside a `v3` namespace without breaking applications that remain on v2.
