All products loaded with the Payments API also come with a custom developer gateway to allow developers to test a payment transaction quickly and easily.
The developer gateway allows anyone selecting it to view the details of an order, and manually approve the transaction.
To turn on the Developer Gateway, you first need to enable the WordPress Debug Mode. Then, the next time you go to your Payments Tab, you will be able to enable the Developer Gateway as one of the gateways.
Warning: Enabling the Developer Gateway allows listings to be created without any payment, by any user. It is recommended that you only have it enabled on a staging environment, as enabling it on a production site will allow users to circumvent the payment process.
