# Overview

Once the integration is complete, you need to test it on the sandbox environment using the sandbox credentials available at API section of the [Sandbox Admin Panel](https://sandbox.transactbridge.com/) and using the [test payment credentials](https://docs.transactbridge.com/#uat-testing) listed here.

When the test transaction is complete, you can move your code to Live or Production environment with production account details.

### Going Live on Production Environment

Replace your sandbox credentials with production credentials.

* API Key
* Secret Key

  * Sandbox: [https://sandbox-api.transactbridge.com](https://sandbox-api.transactbridge.com)
  * Production: [https://api.transactbridge.com](https://api.transactbridge.com)

  The production account details will be available on the [Reseller Admin Panel](https://reseller.transactbridge.com/) only when your account is approved and created by TransactBridge. Please contact your account manager to get the production account created.
