Scenario: 

In the context of implementing e-Invoicing in Malaysia, the terms "sandbox environment" and "production environment" refer to different stages and setups used during the development and deployment of the e-Invoice system.

The sandbox environment is a testing setup where businesses and developers can experiment with the e-Invoice system without affecting real transactions or data. This environment is isolated from the live system, allowing users to:

• Test new features and functionalities.
• Validate integrations and workflows.
• Identify and fix bugs or issues.
• Train staff on the new system.

The sandbox environment mimics the production environment but uses simulated data, ensuring that any errors or issues do not impact actual business operations.

In QNE Optimum, to connect the LHDN API Connection Sandbox environment, user need to fill up the Client ID and Client Secret of the company, and tick the environment as ‘Sandbox’.     

Note:  The Client ID and Client Secret for the Sandbox environment and the Production environment are different. You will need to obtain them separately for each environment.
