Tumblr API

Welcome to the Tumblr API! There isn't anything we enjoy more than seeing talented designers and engineers using Tumblr to invent whole new forms of creative expression. We've put a tremendous amount of care into making this API functional and flexible enough for any projects you throw at it. Join us in our discussion group to talk about how to use it, what could be better, and all the amazing things you're going to build with it. Please use the API responsibly, and send us your feedback. Enjoy!

If you're looking for documentation for the old API, you can find it here.

What You Need

Get an OAuth key: register an application

You'll need this to get your API key, even if you don't ever need to use a fully signed OAuth request.

For more details, see Authentication below.

Overview

Before you dive in, review these essentials.

URI Structure

All Tumblr API requests start with api.tumblr.com. The next segment of the URI path depends on the type of request:

Blog: get blog data or write to a blog
api.tumblr.com/v2/blog/{base-hostname}/...
User: get user data or perform user actions
api.tumblr.com/v2/user/...

See Methods below for complete details.

Blog Hostname

Each blog has a unique hostname. The hostname can be standard or custom.

Standard hostname: the blog short name + .tumblr.com.
Example: greentype.tumblr.com
Custom hostname: Anything at all, as determined by a DNS CNAME entry.
Example: www.davidslog.com

You'll need the blog hostname anytime you work with a blog. When you see the placeholder {base-hostname} in the API docs, substitute the standard or custom hostname.

Response Format

The API returns JSON-encoded objects (content-type: application/json). Responses vary according to the method used, but every response envelope includes these common parts:

meta	The `meta` object matches the HTTP response message: `status`: the 3-digit HTTP Status-Code (e.g., `200`) `msg`: the HTTP Reason-Phrase (e.g., `OK`)
response	API-specific results

Example

{
   "meta": {
      "status": 200,
      "msg": "OK"
   },
   "response": { ... }
}

All requests made with HTTP GET are JSONP-enabled. To use JSONP, append jsonp= and the name of your callback function to the request. JSONP requests will always return an HTTP status code of 200 but will reflect the real status code in the meta field of the JSON response.

About the API Documentation

The docs include some working examples. Please click them to your heart's content, but don't use the embedded API key for your own nefarious purposes. Register your application to get your own API key (your OAuth Consumer Key).

URI Conventions

Notation	Meaning	Example
Curly brackets { }	Required item	`api.tumblr.com/v2/blog/ {base-hostname}/posts` The blog hostname is required.
Square brackets [ ]	Optional item	`api.tumblr.com/v2/blog/ {base-hostname}/posts[/type]` Specifying a post type is optional.

Authentication

The API uses three different levels of authentication, depending on the method.

None: No authentication. Anybody can query the method.
API key: Requires an API key. Use your OAuth Consumer Key as your api_key.
- Example: api_key=PyezS3Q4Smivb24d9SzZGYSuh--IaMfAkE
- Get an OAuth key: register an application
OAuth: Requires a signed request that meets the OAuth 1.0a Protocol.

Each method description includes a note about the authentication level.

OAuth

The API supports the OAuth 1.0a Protocol, accepting parameters via the Authorization header, with the HMAC-SHA1 signature method only. There's probably already an OAuth client library for your platform.

Endpoints

Request-token URL	`http://www.tumblr.com/oauth/request_token`
Authorize URL	`http://www.tumblr.com/oauth/authorize`
Access-token URL	`http://www.tumblr.com/oauth/access_token`
