Build status NuGet version (NewTumblrSharp)


This is a continuation of the excellent TumblrSharp C# Library developed by the community.


Please refer to the Wiki to learn how to use TumblrSharp. A complete documentation can be found here.


TumblrSharp is a very nicely designed library, and perhaps the only usable C# library that currently exists. However, development for the Codeplex project stopped in 2014. While using the library, I've noticed several bugs which I'll fix and post to this repository.

What has been fixed in this new version?

If you download the old TumblrSharp version off of CodePlex or NuGet, you won't get any of the fixes this libary provides - most notably, support for Asks and Submissions.

  • Errors with getting submission posts and their new post state type
  • Allow posts to be sent with a published state, which is currently the only way to publish asks
  • New CreateAnswer method on PostData class allows for editing and publishing asks
  • Eliminated superfluous constructor overloads in PostData methods, allowing for shorter, more maintainable code
  • Eliminated unnecessary required parameters like title or body from a text post, as they are not required by the Tumblr API.
  • Opted for default values in PostData. This is important because specifying something simple like a PostCreationState on a photo post would require possibly unneeded data, like tags.
  • Move everything into a PCL for maximum compatibility.
  • Getting dashboard posts after a date rather than before
  • "Reblogged from" broken
  • Add Reblog Trail support

What needs to be implemented?

  • Better documentation
  • Examples of how to use the library

What will not be implemented?

  • Chat
  • Activity

(This is due to restrictions to the V2 API. These endpoints exist but can only be accessed with the official Tumblr app API key).
