We were exploring RingCentral fax for sending fax. We wanted to attach pdf docs and send it with Java code. But with RingCentral SDK I just wanted to know how do set the mime type or content type in the code. Any example will be helpful.
I tried :
`Attachment attachment = new Attachment();
attachment.fileName = "c:\\ testRun.pdf";`
Is there any way to set the document mime type?
