## PayPal Checkout API SDK for NodeJS

![PayPal Developer](/homepage.jpg)

### To consolidate support across various channels, we have currently turned off the feature of GitHub issues. Please visit https://www.paypal.com/support to submit your request or ask questions within our community forum.

**Welcome to PayPal NodeJS SDK**. This repository contains PayPal's NodeJS SDK and samples for [v2/checkout/orders](https://developer.paypal.com/docs/api/orders/v2/) and [v2/payments](https://developer.paypal.com/docs/api/payments/v2/) APIs.

This is a part of the next major PayPal SDK. It includes a simplified interface to only provide simple model objects and blueprints for HTTP calls. This repo currently contains functionality for PayPal Checkout APIs which includes [Orders V2](https://developer.paypal.com/docs/api/orders/v2/) and [Payments V2](https://developer.paypal.com/docs/api/payments/v2/).

Please refer to the [PayPal Checkout Integration Guide](https://developer.paypal.com/docs/checkout/) for more information.

## Usage

### Binaries

It is not mandatory to fork this repository for using the PayPal SDK. You can refer [PayPal Checkout Server SDK](https://developer.paypal.com/docs/checkout/reference/server-integration) for configuring and working with SDK without forking this code.

For contirbuting or referrring the samples, You can fork/refer this repository.

## Examples

### Creating an Order

#### Code to Execute:

```javascript
import { core, orders, payments } from '@hyperse/paypal-node-sdk';

// Creating an environment
let clientId = '<<PAYPAL-CLIENT-ID>>';
let clientSecret = '<<PAYPAL-CLIENT-SECRET>>';
// This sample uses SandboxEnvironment. In production, use LiveEnvironment
let environment = new core.SandboxEnvironment(clientId, clientSecret);
let client = new core.PayPalHttpClient(environment);

// Construct a request object and set desired parameters
// Here, OrdersCreateRequest() creates a POST request to /v2/checkout/orders
let request = new orders.OrdersCreateRequest();
request.requestBody({
  intent: 'CAPTURE',
  purchase_units: [
    {
      amount: {
        currency_code: 'USD',
        value: '100.00',
      },
    },
  ],
});

// Call API with your client and get a response for your call
let createOrder = async function () {
  let response = await client.execute(request);
  console.log(`Response: ${JSON.stringify(response)}`);
  // If call returns body in response, you can get the deserialized version from the result attribute of the response.
  console.log(`Order: ${JSON.stringify(response.result)}`);
};
createOrder();
```

#### Example Output:

```
{
    "id": "4VW45368HJ294683Y",
    "links": [
        {
            "href": "https://api.sandbox.paypal.com/v2/checkout/orders/4VW45368HJ294683Y",
            "method": "GET",
            "rel": "self"
        },
        {
            "href": "https://www.sandbox.paypal.com/checkoutnow?token=4VW45368HJ294683Y",
            "method": "GET",
            "rel": "approve"
        },
        {
            "href": "https://api.sandbox.paypal.com/v2/checkout/orders/4VW45368HJ294683Y",
            "method": "PATCH",
            "rel": "update"
        },
        {
            "href": "https://api.sandbox.paypal.com/v2/checkout/orders/4VW45368HJ294683Y/capture",
            "method": "POST",
            "rel": "capture"
        }
    ],
    "status": "CREATED"
}
```

## Capturing an Order

Before Capturing an order, it should be approved by the buyer using approve link in the create order response.

### Code to Execute:

```javascript
let captureOrder = async function (orderId) {
  request = new orders.OrdersCaptureRequest(orderId);
  request.requestBody({});
  // Call API with your client and get a response for your call
  let response = await client.execute(request);
  console.log(`Response: ${JSON.stringify(response)}`);
  // If call returns body in response, you can get the deserialized version from the result attribute of the response.
  console.log(`Capture: ${JSON.stringify(response.result)}`);
};

let capture = captureOrder('REPLACE-WITH-APPROVED-ORDER-ID');
```
