# Authorising a payment

[View source](/paypal-hpp/express-checkout-shortcut/authorising-a-payment.md)

**PayPal Express Checkout Shortcut will be deprecated by November 1, 2024.**

We will release the new PayPal Express Checkout on Web Drop-in/Components in April 2024.

If the payment is authorised on PayPal, the authResult URL parameter Adyen returns is authResult=PENDING. Send us a payment authorisation request to complete the PayPal Express Checkout transaction. Provide authentication credentials. You configure these details in the library you use for server-to-server communication with the Adyen payments platform. The username is automatically retrieved when you initiate a payment and should to match the username value you specify when you authenticate to send your authorise API call.

A predefined username isws\@Company.\[YourCompanyAccount]. You set the corresponding password in the [Customer Area](https://ca-test.adyen.com/) > **Developers** > **API credentials**. The payment request authorise API call you make to Adyen always should include the payment token you receive from us in the **payment.token HTTP POST return** field as a key/value pair entry in the `additionalData` container object. Also, the paypal\_ecs value that you passed in the `brandCode` field with the initial HTTP POST message while initiating the payment.

Include the paypal\_ecs brandCode

```
...
 <form id="adyenForm" name="adyenForm" onsubmit="return formValidate(this ,'default' );" autocomplete="off" method="post" action="https://live.adyen.com/hpp/skipDetails.shtml">
 ...
 <input type="hidden" value="paypal_ecs" name="brandCode">
 ...
 </form>
 ...
```

 ...
```
