 ### Switching between the sandbox environment and the production environment
-Authorize.Net maintains a complete sandbox environment for testing and development purposes. The sandbox environment is an exact duplicate of our production environment, with simulated transaction authorization and settlement. By default, this SDK is configured to use the sandbox environment. To switch to the production environment, set the appropriate environment constant using ApiOperationBase `setEnvironment` method. For example:

 ### Transaction Hash Upgrade
 Authorize.Net is phasing out the MD5 based `transHash` element in favor of the SHA-512 based `transHashSHA2`. The setting in the Merchant Interface which controlled the MD5 Hash option is no longer available, and the `transHash` element will stop returning values at a later date to be determined. For information on how to use `transHashSHA2`, see the [Transaction Hash Upgrade Guide](https://developer.authorize.net/support/hash_upgrade/).
