I am trying to implement REST web services in our Oracle Apps which is on 12.1.3 version. I have followed all the steps in the doc ids 556540.1 and 1998019.1. But I don't see the "REST Web Services" tab in the Integration Repository page. Should I set any profile options to enable the REST web services? The document says the REST web services are available in 12.1.3. Are the web services really available in 12.1.3. Please let me know what I am missing. Thanks!
