Capture an Authorization
Note: This guide assumes you have completed a basic Smart Payment Buttons integration.
Complete these steps on the server:
This code:
- Sets up your server to make calls to PayPal.
- Gets the authorization ID from your database.
- Calls PayPal to capture the authorization.
- Saves the order ID to your database.
- Handles any errors from the call.
// Note: This is example code. 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_AUTHORIZATION_API = 'https://api.sandbox.paypal.com/v2/payments/authorizations/'; // 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. Get the authorization ID from your database authorizationID = database.lookupAuthorizationID(); // 3. Call PayPal to capture the authorization capture = http.post(PAYPAL_AUTHORIZATION_API + authorizationID + '/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) { return console.error(capture.error); }
curl -v -X POST https://api.sandbox.paypal.com/v2/payments/authorizations/ <authorization-id>/capture \ -H "Content-Type: application/json" \ -H "Authorization: Bearer Access-Token" \ -H "PayPal-Request-Id: 123e4567-e89b-12d3-a456-426655440010" \

The capture request generates a response with a capture ID that you can use for refunding transactions:
{
"id": "2GG279541U471931P",
"status": "COMPLETED",
"links": [
{
"rel": "self",
"method": "GET",
"href": "https://api.paypal.com/v2/payments/captures/2GG279541U471931P"
},
{
"rel": "refund",
"method": "POST",
"href": "https://api.paypal.com/v2/payments/captures/2GG279541U471931P/refund"
},
{
"rel": "up",
"method": "GET",
"href": "https://api.paypal.com/v2/payments/authorizations/0VF52814937998046"
}
]
}
For the full list of parameters and example responses, see capturing authorized payments in the Payments API reference.
Note: Remember to swap the credentials and API URL from sandbox to production when going live with your integration.
You can now call the PayPal Orders API to capture an authorization.
