Update Document Set using REST API in SharePoint 2013

You can perform essential create, read, update, and delete (CRUD) operations by REST API in SharePoint 2013. The REST interface exposes all the SharePoint entities and services available in the other SharePoint client APIs. One advantage of using REST is that you don’t have to add references to any SharePoint libraries or client assemblies. Instead, you make HTTP requests to the appropriate endpoints to retrieve or update SharePoint entities, such as webs, lists, and list items.
