    Get your CLIENT_ID and CLIENT_SECRET in the following link.

    Other options have been added and you can choose any time after installation:


- **Sandbox:** By default, sandbox have been selected. We believe, you need a environment to test your first payment.

- **Kind of Checkout:** Now you can choose what kind of checkout has adapted better with your front-end design, we recommend checkout transparent.

- **Instant Payment Notification (IPN) URL:** In this part, you can check your IPN URL, where you will get notified about payment updates.
