# Test Your Integration and Go Live (/archive/paypal-plus/de/integrate/test-and-go-live)



> **Note:** **Important:** PayPal Plus Germany is not available for new integrations. PayPal provides this documentation to support existing integrations. For new integrations, see the [PayPal Checkout Integration Guide](/checkout).

## Test [#test]

The PayPal test environment, sandbox, is a mirror of the PayPal live system. Any part of the PayPal integration can be tested in this environment without *real* funds being moved.

PayPal recommends using the sandbox for ensuring your integration is working before switching to the live system.

## Go live [#go-live]

When testing is complete and you are ready to go live:

1. Change the API endpoint from `https://api-m.sandbox.paypal.com` to `https://api-m.paypal.com`.
2. Change the environment in the configuration element of the PLUS library by commenting out `"mode": "sandbox"` or replace `sandbox` with `live`.
3. Change your sandbox client ID and secret credentials to the live client ID and secret credentials. To get the live credentials, generate a new REST app or navigate to the credentials view of your app and switch to live
4. Enable your live account for PayPal PLUS.
