5 Sample script
This section presents the various components of the Storage Center REST API discussed in previous
sections and assembles it into a cohesive, functional, and complete sample script. This sample script is
annotated to explain statements or sections as needed.
Additional code can be injected into this complete sample script where denoted by the placeholder:
"===== YOUR CODE GOES HERE =====".
The following assumptions are made regarding the code:
• Assumes a true or successful condition (return code) from each requested REST API call
• Contains minimal error trapping and management to promote readability and understanding
• Creates the data structures required to facilitate passing the data between REST API calls
