Do you develop themes? Great! Stand right here. Now listen.
We made a new Theme ManagementĀ page. It looks nice and itās been filled with useful numbers. Among them:
Your daily, monthly, and all-time install counts
A day-by-day graph of installs over the last 30 days
The 250 blogs which most recently installed your work
A chart of the relative performance of each of your themes (premium themes only)
Excited? Want to make a new theme just to watch it get managed? Go ahead and do so at tumblr.com/themes/new, which is another page weāve gone and improved.

Hey there, cool theme developers!
We added a simple file manager to tumblr.com/customize. It allows theme assets to be uploaded right from the Customize interface, so youāll never have to visit the static file uploader again. You can also insert and automatically update the asset URLs in the source code for your theme. Yes!

Hey all,
Iām happy to announce the release of the 0.8.0 version of our tumblr_client gem! This release is a major bump from our 0.7.5 release! An important update is the deprecation of the :raw_data parameter for posting. If you need this parameterĀ do not update past 0.7.5.
Changelog
Removing support for :raw_data parameter for posting
Adding support for multipart file uploading
Removing all custom OAuth code and letting better tested libraries take care of it for us!
Allowing you to configure any of your favorite ruby HTTP clients supported by Faraday!
And if you have any issues, let me know here or @codingjester on Twitter or report issues directly here.
Get hacking everyone!Ā
You asked, we delivered: Ā Hereās your fancy new developerās console so you can see results of your API calls and live examples of our API clients. Boom!

Hello fearless Tumblr app developers!
Today we're pushing a few changes to our Application Developer and API License Agreement that we wanted to make you aware of. These changes likely won't impact the majority of you.
We made a few cosmetic edits to soften and clarify language in the agreement.
We modified the terms to apply to those developers building applications using our data firehose. This is mainly a mechanical change to the document.
We added restrictions against modifying the order of content that we send you, and clarified that anything we insert (like sponsored content!) shouldn't be removed.
We clarified our previous restriction on public re-display.
Location should reflect real, mappable geography.
We clarified our policy on collection of private information, emphasizing the need for user notice and consent when appropriate.
As always, if you have any questions or concerns, please send an email toĀ [email protected]Ā and check out ourĀ developer forum.
ATTN: fantastic theme developers! Tumblr users can now interact with posts straight from the blog index and permalink pages on your theme! This is super exciting news! Previously blog visitors could only like or reblog posts through the controls in the corner of post permalinks.
All you have to do is incorporate our new Like and Reblog buttons anywhere in your design ā weāll take care of the rest.
If youāve been using other methods to add this functionality to your themes, youāll need to update to the latest code. Visit our updated Theme Developers documentation for more information.

Last week, two of our engineers, Wolf and JC, got to stay up all night eating pizza with some really talented young hackers at two different hackathons ā 2013 hackNY Student Hackathon at Columbia University and Photo Hack Day at Facebook HQ.
After a long day of hacking, pizza, sleep deprivation, more pizza, and some DIY tacos, participants demoed their hacks, including a few for the Tumblr API. We were absolutely blown away by the creativity and quality of the projects and look forward to seeing what youāll build at the next hackathon!
Over the past few weeks weāve open-sourced quite a few official client libraries for the Tumblr API. Today Iām proud to announce the Tumblr iOS SDK, an Objective-C library for easily integrating Tumblr data into your iOS (or OS X) applications, however you see it.
The Tumblr SDK for iOS contains a few different components to start:
Authentication (OAuth and xAuth implementations)
A full wrapper around all of our API endpoints
Inter-app communication (this is pretty limited at the moment but we plan to expand it quite a bit going forward)
A UIActivity stub for easy inclusion of a Tumblr button in a standard Apple UIActivityViewController
Weāve been using this SDK in production for quite some time now and are thrilled to finally be able to share it with you.
If youāre interested in integrating with Tumblr on iOS or OS X in a way that the SDK doesnāt currently facilitate, please get in touch. Iām very interested in hearing any and all feedback on how we can make this as easy as possible.
tumblr.php
Iām here to announce another new addition to our list of official API clients. This week we have tumblr.php - itās available on GitHub and composer via packagist. It is tested, is PSR-2 compatible, and is well documented.
Like the other clients weāve been announcing (most recently JS and Java) it has full support for all of the Tumblr v2 API endpoints.
Time to make something cool!
tumblr Java client: jumblr
Last week we announced our first official API client, for JavaScript (read: the announcement). This week weāre back to announce the release of an official Java client, Jumblr:
Blog blog = client.blogInfo("seejohnrun.tumblr.com"); for (Post post : blog.posts()) { post.like(); // you're too kind.. }
Like its JavaScript counterpart, Jumblr comes with full support for all of the API V2 endpoints. Check out more detail on the github page!
If youāre interested in following along with any of our open-source work, check out our GitHub page.
tumblr.js JavaScript client
Today Iām excited to announce the release of tumblr.js, the first of several official API clients weāll be rolling out over the next few months.
You can install it now with npm, and start making something awesome:
var tumblr = require('tumblr.js'); var client = tumblr.createClient({ consumer_key: 'consumer_key', consumer_secret: 'consumer_secret', token: 'oauth_token', token_secret: 'oauth_token_secret' }); // Name all of the authenticating user's blogs client.userInfo(function (err, data) { data.user.blogs.forEach(function (blog) { console.log(blog.name); }); });
It comes with full support for all of the API V2 endpoints including tag search, following, liking, and post creation. For more detail, see the GitHub page.
More to come soon!
