PayPal Checkout
Capture Transaction Funds
Note: This guide assumes you have completed a basic Smart Payment Buttons integration.
On the server
- Set up your server to make calls to PayPal
- Set up your server to receive a call from the client with the order ID
- Call PayPal to capture the order
- Save the capture ID to your database
- Handle any errors from the call
- Return a successful response to the client
Note: To install the PayPal SDK on your server, see the Set up Server-Side SDK guide. If you are calling the API directly, you do not need to install the SDK.
// Note: This code is intended as a *pseudocode* example. Each server platform and programming language has a different way of handling requests, making HTTP API calls, and serving responses to the browser.
// 1. Set up your server to make calls to PayPal
// 1a. Add your client ID and secret
PAYPAL_CLIENT = 'PAYPAL_SANDBOX_CLIENT';
PAYPAL_SECRET = 'PAYPAL_SANDBOX_SECRET';
// 1b. Point your server to the PayPal API
PAYPAL_OAUTH_API = 'https://api.sandbox.paypal.com/v1/oauth2/token/';
PAYPAL_ORDER_API = 'https://api.sandbox.paypal.com/v2/checkout/orders/';
// 1c. Get an access token from the PayPal API
basicAuth = base64encode(`${ PAYPAL_CLIENT }:${ PAYPAL_SECRET }`);
auth = http.post(PAYPAL_OAUTH_API {
headers: {
Accept: `application/json`,
Authorization: `Basic ${ basicAuth }`
},
data: `grant_type=client_credentials`
});
// 2. Set up your server to receive a call from the client
function handleRequest(request, response) {
// 2a. Get the order ID from the request body
orderID = request.body.orderID;
// 3. Call PayPal to capture the order
capture = http.post(PAYPAL_ORDER_API + orderID + '/capture', {
headers: {
Accept: `application/json`,
Authorization: `Bearer ${ auth.access_token }`
}
});
// 4. Save the capture ID to your database
if (!capture.error) {
captureID = capture.purchase_units[0]
.payments.captures[0].id;
database.saveCaptureID(captureID);
}
// 5. Handle any errors from the call
if (capture.error) {
console.error(capture.error);
return response.send(500);
}
// 6. Return a successful response to the client
response.send(200);
}
// 1. Set up your server to make calls to PayPal
// 1a. Import the SDK package
const checkoutNodeJssdk = require('@paypal/checkout-server-sdk');

Note: Remember to swap the credentials and API URL from sandbox to live when going live with your integration.
On the client
Next, change the onApprove function on your client. This function now calls your server with the order ID and no longer call actions.order.capture().
onApprove: function(data) {
return fetch('/my-server/capture-paypal-transaction', {
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: data.orderID
})
}).then(function(res) {
return res.json();
}).then(function(details) {
alert('Transaction funds captured from ' + details.payer_given_name);
}
Now your client and server are set up to call the PayPal Orders API to capture funds from a transaction.
