Step 3: Authorize a PayPal source
When you create a PayPal source, the customer is required to authorize the charge at PayPal. You can accomplish this by either redirecting the customer to PayPal or using the PayPal SDK to authorize the charge as part of your experience.
Redirecting the customer to PayPal for authorization
To redirect your customer to PayPal for authorization, use the redirectUrl parameter in your createSource response.
1
window.location.href = sourceResponse.redirect.redirectUrl;
Copied!
At PayPal, the customer can authorize or cancel the transaction when presented with the transaction details. If the authorization is successful, the customer will be redirected to the PayPal Return URL parameter you specified when you created the source. If the customer cancels, they will be returned to the PayPal Cancel URL parameter you specified.
Using the PayPal SDK to authorize payment
Use the PayPal Checkout SDK to streamline the authorizing PayPal transactions. This will allow you to control things like the appearance of the PayPal button and embed the entire experience into your workflow.
The PayPal SDK guide is located here: https://developer.paypal.com/docs/archive/checkout/​
More details on how you can customize the PayPal button is located here: https://developer.paypal.com/docs/archive/checkout/how-to/customize-button/#​
Example:
1.Include the PayPal Checkout SDK on your page and specify a location where the button will appear.
2. Use the PayPal SDK to customize and place the PayPal button on your page. The PayPal SDK returns two functions, onAuthorize and onCancel. If the payment was authorized, use the source you created earlier by attaching to an order or cart.

Step 3: Authorize a PayPal Credit source
When you create a PayPal Credit Source, the customer is required to authorize the charge at PayPal. You can accomplish this by either redirecting the customer to PayPal or use the PayPal SDK to authorize the charge as part of your experience.
Redirecting the customer to PayPal for authorization
To redirect your customer to PayPal for authorization, use the redirectUrl parameter in your createSource response.
Redirect example
1
window.location.href = sourceResponse.redirect.redirectUrl;
Copied!
PayPal will present the customer with the transaction details where they can authorize or cancel the transaction. A successful authorization redirects the customer to the PayPal Return URL parameter you specified when you created the source. If the customer cancels, they will return to the PayPal Cancel URL parameter you specified when you created the source.
Using the PayPal SDK to authorize payment
Use the PayPal Checkout SDK to streamline the authorizing PayPal transactions. This will allow you to control things like the appearance of the PayPal button and embed the entire experience into your workflow.
The PayPal SDK guide is located here: https://developer.paypal.com/docs/archive/checkout/​
For more details on how you can customize the PayPal button, go to https://developer.paypal.com/docs/archive/checkout/how-to/customize-button/#​
Example:
1.Include the PayPal Checkout SDK on your page and specify a location where the button will appear.
1
<script src="https://www.paypalobjects.com/api/checkout.js"></script>
2
<div id="paypal-button"></div>
Copied!
2. Use the PayPal SDK to customize and place the PayPal button on your page. The PayPal SDK returns two functions, onAuthorize and onCancel. If the payment was authorized, use the source you created earlier by attaching to an order or cart.
