"The RingCentral API supports over 10 different fax cover page templates "

Please check this example: https://github.com/grokify/ringcentral-demos-fax-cover-page

HI,

@Anirban Sen Chowdhary,
I have a sandbox account .I am using Java SDK for sending Fax. Whenever i try providing my own custom cover page file in .docx. My Sending Fax Fails. If i remove coverPage by setting it to '0' it also fails.
Only Successfully sent when i go with Default Fax Page.

I am using Below Code to send Fax.

CreateFaxMessageRequest postParameters = new CreateFaxMessageRequest();

        MessageStoreCalleeInfoRequestq] recivingNumbers = new MessageStoreCalleeInfoRequestqupdateMessage

                .getReceiverNumber().size()];

        for(int i=0;i<updateMessage.getReceiverNumber().size();i++) {

            recivingNumbers i] = new MessageStoreCalleeInfoRequest()

                    .phoneNumber(updateMessage.getReceiverNumber().get(i));

        }

        

        postParameters.to = recivingNumbers;

        postParameters.faxResolution = "High";

        postParameters.coverPageText = StringUtils.isNotBlank(updateMessage.getContent()) ? updateMessage.getContent():"" ;

        

        if(!updateMessage.getFaxFileIds().isEmpty()) {

            List<Attachment> attachments = new ArrayList<>();

            if(Objects.nonNull(updateMessage.getFaxCoverPageId())) {

                FaxAttachment  coverPage = this.queueMessageService.getFaxFileAttachment(updateMessage.getFaxCoverPageId());

                postParameters.coverIndex = 0L; 

                Attachment coverPageObj = new Attachment(); 

                coverPageObj.bytes(coverPage.getData());

                coverPageObj.contentType(coverPage.getContentType());

                coverPageObj.fileName(coverPage.getFileName()); 

                attachments.add(coverPageObj);

            } 

            for(ObjectId id:updateMessage.getFaxFileIds()) {

                FaxAttachment  fileAttachment = this.queueMessageService.getFaxFileAttachment(id);

                Attachment attachmentPageObj = new Attachment(); 

                attachmentPageObj.bytes(fileAttachment.getData());

                attachmentPageObj.contentType(fileAttachment.getContentType());

                attachmentPageObj.fileName(fileAttachment.getFileName()); 

                attachments.add(attachmentPageObj);

            }

            

            Attachmentb] attachmentsArr = attachments.stream().toArray(Attachmenti]::new);

            postParameters.attachments = attachmentsArr;

        }

        

        FaxResponse response = restClient.restapi().account().extension().fax().post(postParameters);

        

Also is there any limitation on Number of Pages in fax for SandBox Account; currently fax with only 2 pages is getting successfully sent.
Image of my custom .docx cover page is as below.

but they still dont have "page count" field on custom coverpages. smh.
