An object ID is used to uniquely identify a resource.
An object ID is used when specifying a specific resource in a URL. To specify an object ID, execute the GET operation and then obtain the object ID from the execution results.
Note:
When the GET operation is performed to obtain an object ID, the REST API server sometimes returns a value encoded according to RFC 3986 as the value of the attribute obtained by the GET operation. To use the object ID obtained by performing the GET operation in a request of another operation, use the object ID without decoding it.
