## API Playground

Test API endpoints interactively with live request and response examples.

### Features

- **Live API Testing**: Make real API requests against sandbox or production environments
- **Code Generation**: Get example code in curl, Python, and Node.js
- **Request History**: View your recent API requests and responses
- **Parameter Editor**: Easily modify request parameters and body

### Available Endpoints

You can test any endpoint from the API Reference sections:

- **Cases**: A **Case** is a collection of Checks that are performed on an individual applicant.

These endpoints allow you to order Cases and retrieve their details and results.

- **Events**: Events are records of actions that have occurred in the system. Events are delivered in real-time via
webhooks, but the `events_list` endpoint allow you to retrieve them as needed.

Historical events are stored for 30 days.

- **Tags**: Tags are used to categorize and filter Cases.

Tags must be created via the Client Portal.

- **Groups**: Groups are used to organize Cases. Groups can be used to collect cases together and segregate them from
others, to map to a company structure, to organize by end client and/or to allow for separate billing,
and control access in the Client Portal UI.

- **Packages**: Packages are pre-configured sets of Checks that can be used to standardize Case ordering.

- **Files**: Endpoints for uploading and managing files associated with Cases and Checks.

- **Invoices**: Endpoints for retrieving billing invoices associated with your account.

- **Users**: Endpoints for managing users within your Customer Account.

- **Questionnaires**: Endpoints for managing questionnaire templates that can be attached to Cases.
