PayPal V2 introduces the PayPal Checkout, which features a RESTful API solution that includes standard checkout, PayPal Express, and the new PayPal Vault functionality. With these flexible and powerful payment solutions, we aim to enhance the e-commerce experience for both merchants and their customers. By enabling customers to quickly complete transactions using their PayPal accounts, this integration reduces cart abandonment and accelerates the payment process. PayPal V2 offers streamlined authentication and approval steps, ensuring a secure, efficient, and user-friendly checkout experience for your e-commerce platform. In addition to the standard checkout, you also have the option to utilize the JavaScript SDK to render PayPal buttons and respond to various PayPal events.
We provide the flexibility to implement payment options across multiple pages:
The PayPal Checkout V2 handles the regular checkout. For more information about the Product page and Shopping Cart page please use our PayPal Express V2 implementation guide.
There are two options for rendering the PayPal button: merchants can choose between a dynamic PayPal button or the standard JavaScript SDK to create buttons and respond to key events (onApprove, onError, onCancel, onShippingChange).
The JavaScript Button Render provides a straightforward and efficient way to integrate the PayPal button into your website, enhancing both functionality and user experience. To ensure that the PayPal button functions correctly and delivers a seamless checkout process, you will need to prepare the following components:
Partner id LIVE: given by PAYONE
Endpoint: api.paypal.com ( or api-m.paypal.com )
Client id: generated in your PayPal developer account
Secret: generated in your PayPal developer account
|
The display of payment and shipping might change depending on the shipping address retrieved from PayPal. Therefore you have the option to patch/update your order after the redirection from PayPal back to the merchant.
PayPal allows the configuration of the initiation script via Query parameters to help define specific content or actions based on the data being passed. Each piece of data sent contains:
In this example, the script includes the following query parameters:
<script src="https://www.paypal.com/sdk/js?client-id=Axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&merchant-id=LXXXXXXXXXXXXX¤cy=EUR&intent=authorize&locale=de_DE&commit=true&vault=false&disable-funding=card,sepa,bancontact&enable-funding=paylater"></script>
For debug purpose you can also add the parameter
debug: true/false
