Setting Up PayPal Sandbox Accounts
The PayPal Sandbox allows you to setup test accounts that can be used to test the full registration process in Restrict Content Pro with the PayPal gateways.
To create a sandbox account, visit http://developer.paypal.com and click Login or Signup if you do not already have an account set up. You can log in with your existing PayPal account.
Once logged in, click on Dashboard in the top menu:
Dashboard will take you to a screen that looks like this:
Now click on the Accounts link under the Sandbox menu, which will take you to this page:
Click on the blue Create Account button in the top right corner of the screen. You will now be presented with an account creation form:
Select your country and choose Business for the account type. All other fields can be filled out however you wish.
Once the account is created, it will be shown in the Accounts list under the Sandbox menu.
Click on the account and click on Profile:
This will open a popup window. Click on the API Credentials tab and copy those credentials to Restrict > Settings > General, as shown in the setup instructions for PayPal Pro, PayPal Express, and PayPal Standard.
You can log in with your sandbox credentials at https://www.sandbox.paypal.com just like the live PayPal site. This is where you can view your test transactions, set up your sandbox IPN, etc. You can learn more about sandbox testing here: https://developer.paypal.com/docs/classic/lifecycle/sb_overview/
