The Prediction Studio APIs facilitate the monitoring and management of predictions remotely, using the scripting language of your choice. They offer endpoints for various operations, such as getting a list of Predictions and their attributes, introducing a challenge model, and more. These operations are categorized under Data export, Models, Reporting, Predictions, and Prediction Studio. As a System Admin, you generate the client credentials that provide access to the APIs, and then inspect the API responses.

Use the following credentials to log in to the exercise system:

Role	User name	Password
System Admin	SystemAdmin	rules

Your assignment consists of the following tasks:

Task 1: Generate the ADM export artifacts

Generate the dataflows to export the ADM model and predictor snapshots.

Task 2: Generate a Client ID and a Client Secret

Generate a Client ID and a Client Secret for access to the Prediction Studio APIs.

Task 3: Inspect the API responses

Use REST calls to try out the Prediction Studio APIs.
