Examples

Creating an Order

Code to Execute:

const paypal = require('@paypal/checkout-server-sdk');
  
// Creating an environment
let clientId = "<<PAYPAL-CLIENT-ID>>";
let clientSecret = "<<PAYPAL-CLIENT-SECRET>>";
let environment = new paypal.core.SandboxEnvironment(clientId, clientSecret);
let client = new paypal.core.PayPalHttpClient(environment);

// Construct a request object and set desired parameters
// Here, OrdersCreateRequest() creates a POST request to /v2/checkout/orders
let request = new paypal.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:

let captureOrder =  async function(orderId) {
    request = new paypal.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');
