Hi there,

I'm using RingCentral SDK 2.4 to test the API to send High Volume SMS (HV SMS). My application has been approved and active on PROD environment.

I'm using the sample code as bellow:

    CreateSMSMessageBatchRequest parameters = new CreateSMSMessageBatchRequest();

    parameters.from = "+14082223XXX";

    parameters.text = "Hello Team, This is MOSO called High Volume APIs";

    String[] numbers = new String[] {"+14243325470", "+14243325455"};

    parameters.messages = new MessageCreateRequest[numbers.length];

    for (int i=0; i<numbers.length; i++) {

      MessageCreateRequest m = new MessageCreateRequest();

      m.to = new String[] {numbers[i]};

      parameters.messages[i] = m;

    }

    for (int i = 0; i < 2 ; i++ ) {

      MessageBatchInfo post = restClient.restapi().account().a2pSms().batches().post(parameters);

      System.out.println(post.from + " - " + post.id + " - " + post.creationTime +

              " - " + post.status + " - " + post.batchSize + " - " + post.processedCount);

    }

But i alway got this (404) error message:

status code: 400

I'm pretty sure that the from number already correct.
