With the development of eCommerce today, PayPal has become one of the most popular payment options that many people around the world prefer. Therefore, integrating with online stores is also the top priority with any merchant.

However, PayPal is a third-party payment, so it sometimes causes problems during the checkout process. This, in many cases, makes customers confused and can lead to cart abandonment.

So, how can we fix it? How can people test the integration between PayPal and eCommerce stores before offering it to customers?

The solution for it is PayPal sandbox. Understanding the difficulty of entrepreneurs, PayPal introduced the sandbox mode to its users, which creates a mock transaction for them to test. This mock test is entirely the same as in the live environment, so merchants can check it without affecting other customers.

In this post, we will guide you on how to set up PayPal sandbox on WooCommerce as well as use it to test transactions.

Benefits of PayPal sandbox

Via PayPal sandbox, merchants will have opportunities to test their checkout process before actually launching it. By doing that, they can make sure that their customers will be served with the best services and complete the purchase with no problems, especially in terms of money, which are usually regarded as sensitive.

More than that, the sandbox mode in PayPal is a helpful tool for store owners to figure out problems or limitations in the checkout process. Only when putting themselves in their customers’ shoes, do merchants understand their demand and feelings to improve their store? Hence, their customers will be able to experience a fantastic shopping journey in your store.
