/**
 * <p>Retrieves the history of all changes to a parameter.</p>
 *          <p>Parameter names can't contain spaces. The service removes any spaces specified for the
 *    beginning or end of a parameter name. If the specified name for a parameter contains spaces
 *    between characters, the request fails with a <code>ValidationException</code> error.</p>
 *          <important>
 *             <p>If you change the KMS key alias for the KMS key used to encrypt a parameter,
 *     then you must also update the key alias the parameter uses to reference KMS. Otherwise,
 *      <code>GetParameterHistory</code> retrieves whatever the original key alias was
 *     referencing.</p>
 *          </important>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { SSMClient, GetParameterHistoryCommand } from "@aws-sdk/client-ssm"; // ES Modules import
 * // const { SSMClient, GetParameterHistoryCommand } = require("@aws-sdk/client-ssm"); // CommonJS import
 * // import type { SSMClientConfig } from "@aws-sdk/client-ssm";
 * const config = {}; // type is SSMClientConfig
 * const client = new SSMClient(config);
 * const input = { // GetParameterHistoryRequest
 *   Name: "STRING_VALUE", // required
 *   WithDecryption: true || false,
 *   MaxResults: Number("int"),
 *   NextToken: "STRING_VALUE",
 * };
 * const command = new GetParameterHistoryCommand(input);
 * const response = await client.send(command);
 * // { // GetParameterHistoryResult
