  • Article

TFS 2017 | TFS 2015 | TFS 2013

Note

Looking for REST APIS that support TFS 2018 or later versions? See the Azure DevOps REST API Reference.

This resource has been deprecated as of api-version = 3.0-preview. Please use the comments API instead.

api-version = 1.0

Discussion history is a list of comments provided by user on a work item. These are stored as part of revisions but this endpoint is a short-hand way to view the complete discussion of a work item.

If you haven't already, look at the information on getting started with these APIs.
