This documentation is for the submodule of the Commerce PayPal project. Support / feature requests and module or documentation feedback should not be posted to these comments. Please use the project issue tracker instead.
- Install the PayPal module and the PayPal WPS module.
- Enable the default Rule for the payment method at Store > Configuration > Payment methods. Edit the Rule and configure the default action that enables the payment method to use your PayPal API credentials. During development, you should use the sandbox if possible and may also want to turn on full IPN logging to log all IPN activity to the watchdog.
- Perform payment tests in the sandbox to ensure you're receiving and processing IPNs as expected. This requires a public server for testing and should result in payment transactions being created for your orders.
