For testing with PayPal, we recommend creating low-cost products and walking through live paid transactions. Using this method, you can verify that your checkout process flows as expected, and confirm that your site is fully configured to manage subscriptions and to issue refunds for PayPal payments.
Note: In older versions of MemberMouse, the “Enable Test Mode” checkbox in the PayPal section of the Payment Settings is a legacy setting. Testing using PayPal Sandbox is no longer fully supported.
