 *             <p>
 *                <b>For the latest version of AWS
 *       WAF</b>, use the AWS WAFV2 API and see the <a href="https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html">AWS WAF Developer Guide</a>. With the latest version, AWS WAF has a single set of endpoints for regional and global use. </p>
 *          </note>
 * 		       <p>Returns the status of a <code>ChangeToken</code> that you got by calling <a>GetChangeToken</a>. <code>ChangeTokenStatus</code> is
 * 			one of the following values:</p>
 * 		       <ul>
 *             <li>
 *                <p>
 *                   <code>PROVISIONED</code>: You requested the change token by calling <code>GetChangeToken</code>, but you haven't used it yet
 * 				in a call to create, update, or delete an AWS WAF object.</p>
 *             </li>
 *             <li>
 *                <p>
 *                   <code>PENDING</code>: AWS WAF is propagating the create, update, or delete request to all AWS WAF servers.</p>
 *             </li>
 *             <li>
 *                <p>
 *                   <code>INSYNC</code>: Propagation is complete.</p>
 *             </li>
 *          </ul>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { WAFRegionalClient, GetChangeTokenStatusCommand } from "@aws-sdk/client-waf-regional"; // ES Modules import
 * // const { WAFRegionalClient, GetChangeTokenStatusCommand } = require("@aws-sdk/client-waf-regional"); // CommonJS import
 * // import type { WAFRegionalClientConfig } from "@aws-sdk/client-waf-regional";
 * const config = {}; // type is WAFRegionalClientConfig
 * const client = new WAFRegionalClient(config);
 * const input = { // GetChangeTokenStatusRequest
 *   ChangeToken: "STRING_VALUE", // required
 * };
 * const command = new GetChangeTokenStatusCommand(input);
 * const response = await client.send(command);
 * // { // GetChangeTokenStatusResponse
 * //   ChangeTokenStatus: "PROVISIONED" || "PENDING" || "INSYNC",
 * // };
 *
 * ```
 *
 * @param GetChangeTokenStatusCommandInput - {@link GetChangeTokenStatusCommandInput}

 *
 * @throws {@link WAFInternalErrorException} (server fault)
 *  <p>The operation failed because of a system problem, even though the request was valid. Retry your request.</p>
