// GetChangeTokenRequest returns a request value for making API operation for
// AWS WAF.
//
//
// This is AWS WAF Classic documentation. For more information, see AWS WAF
// Classic (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide.
//
// For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS
// WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html).
// With the latest version, AWS WAF has a single set of endpoints for regional
// and global use.
//
// When you want to create, update, or delete AWS WAF objects, get a change
// token and include the change token in the create, update, or delete request.
// Change tokens ensure that your application doesn't submit conflicting requests
// to AWS WAF.
//
// Each create, update, or delete request must use a unique change token. If
// your application submits a GetChangeToken request and then submits a second
// GetChangeToken request before submitting a create, update, or delete request,
// the second GetChangeToken request returns the same value as the first GetChangeToken
// request.
//
// When you use a change token in a create, update, or delete request, the status
// of the change token changes to PENDING, which indicates that AWS WAF is propagating
// the change to all AWS WAF servers. Use GetChangeTokenStatus to determine
// the status of your change token.
//
//    // Example sending a request using GetChangeTokenRequest.
//    req := client.GetChangeTokenRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
//    }
