PayPal Sandbox for testing

Tutorial created by Ray Borduin, WebAssist

Categories: eCart, PowerStore


The PayPal sandbox allows you to process transactions on your website, without the official exchange of money. This is one way for PayPal users to test purchases on their online store, prior to going live.

However, we suggest not using PayPal Sandbox at all. WebAsisst code has been throughly tested over the years. The reality is that the sandbox APIs are spread through multiple pages and can be cumbersome to update. It is often much better to just use live PayPal transactions.

Create a $1 item in your store for testing purposes and then simply refund test transactions. PayPal refunds all fees with refunded transactions, so there is no real drawback to this technique and there are some clear advantages since you can be testing with the live code without having to make updates after.
