To use cURL to access the REST API:

- Install cURL, as described in Quick Start.

- Invoke cURL and specify one or more of the command-line options defined in the following table, as required, to direct its execution.

  cURL Option | Description
  --- | ---
  `-d, --data @file.json` | Identifies the request document, in JSON format, on the local machine.
  `-F, --form @file.json` | Identifies form data, in JSON format, on the local machine.
  `-H` | Defines the Content type of the request document.
  `-i` | Displays response header information.
  `-u, --user username:password` | Specifies the user name and password for the <ProductName> account.

The sample files can help in creating an application that requires managing the Oracle Database Appliance using Java as a language. The sample files use DCSAgentClient API class to manage database related life cycle operations such as listDatabases, createDatabase, updateDatabase, ObjectStoreSwift operations and many more. The following are representative samples of the REST APIs.

The following is an example syntax for cURL command:

    curl -i -X GET -u <username>:<password> -H <request-header>:<value> https://<subdomain>.<domain>.com/<path>/<resource-path>
