The Sandbox URL:
The Production URL:
The Sandbox environment is a playground used for testing, and calls do not hit the data service vendors. Dummy data can be used in the Sandbox environment, and the environment can be used for training or testing purposes. If you want to call the Sandbox environment, use the Sandbox API.
The Production environment is used to run real production data, and calls are made to the actual data services (meaning charges are incurred). Dummy data cannot be used in the Production environment. If you want to call the Production environment, use the Production API.
You control Sandbox vs. Production on your side through the API endpoint URL for those evaluations.
Any evaluation tokens with the prefix of S- were created in the Sandbox environment. Any evaluation tokens with the prefix of L- were created in the Production environment. Regardless of environment, all individual entity-types will have entity tokens with the prefix of P-, while all business entity-types will have entity tokens with the prefix of B-.
