# Display funding source used (/v5/checkout/show-fund-source)

Customize your PayPal checkout experience by displaying the funding source used by the buyer on the confirmation page or notification.



Display the funding source used to your buyers to provide a unique experience.

If you have a confirmation page or notification in your checkout workflow, display the payment source the payer selected.

For example, if the payer paid with Venmo, show Venmo as the payment source on the confirmation page or notification.

## Show funding source [#show-funding-source]

Your Checkout experience might have a confirmation page or a notification to the user that they're paying with PayPal. Ensure the funding source the user chose, such as Venmo, shows as expected or it might lead to confusion and reduced Checkout conversion.

Use an `onClick` handler to get the funding source and display it on a confirmation page.

```javascript lineNumbers
let fundingSource;

paypal.Buttons({
  onClick: (data) => {
    // fundingSource = "venmo"
    fundingSource = data.fundingSource;

    // Use this value to determine the funding source used to pay
    // Update your confirmation pages and notifications from "PayPal" to "Venmo"
  },
});
```

The following table shows supported `fundingSource` values:
