Access your site's data through an easy-to-use HTTP REST API. (Version 2)
WordPress is moving towards becoming a fully-fledged application framework, and we need new APIs. This project was born to create an easy-to-use, easy-to-understand and well-tested framework for creating these APIs, plus creating APIs for core.
This plugin provides an easy to use REST API, available via HTTP. Grab your site’s data in simple JSON format, including users, posts, taxonomies and more. Retrieving or updating data is as simple as sending a HTTP request.
Want to get your site’s posts? Simply send a GET
request to /wp-json/wp/v2/posts
. Update user with ID 4? Send a PUT
request to /wp-json/wp/v2/users/4
. Get all posts with the search term “awesome”? GET /wp-json/wp/v2/posts?filter[s]=awesome
. It’s that easy.
The WordPress REST API exposes a simple yet easy interface to WP Query, the posts API, post meta API, users API, revisions API and many more. Chances are, if you can do it with WordPress, the API will let you do it.
The REST API also includes an easy-to-use JavaScript API based on Backbone models, allowing plugin and theme developers to get up and running without needing to know anything about the details of getting connected.
Check out our documentation for information on what’s available in the API and how to use it. We’ve also got documentation on extending the API with extra data for plugin and theme developers!
All tickets for the project are being tracked on GitHub. You can also take a look at the recent updates for the project.
Install the WP REST API via the plugin directory, or by uploading the files manually to your server.
For full-flavoured API support, you’ll need to be using pretty permalinks to use the plugin, as it uses custom rewrite rules to power the API.
Once you’ve installed and activated the plugin, check out the documentation for details on your newly available endpoints.

Introduce support for Post Meta, Term Meta, User Meta, and Comment Meta in
their parent endpoints.
For your meta fields to be exposed in the REST API, you need to register
them. WordPress includes a register_meta()
function which is not usually
required to get/set fields, but is required for API support.
To register your field, simply call register_meta and set the show_in_rest
flag to true. Note: register_meta must be called separately for each meta
key.
(props @rmccue, @danielbachhuber, @kjbenk, @duncanjbrown, #2765)
Introduce Settings endpoint.
Expose options to the REST API with the register_setting()
function, by
passing $args = array( 'show_in_rest' => true )
. Note: WordPress 4.7 is
required. See changeset [38635][https://core.trac.wordpress.org/changeset/38635].
(props @joehoyle, @fjarrett, @danielbachhuber, @jonathanbardo,
@greatislander, #2739)
Attachments controller, change permissions check to match core.
Check for the upload_files
capability when creating an attachment.
(props @nullvariable, @adamsilverstein, #2743)
Add ?{taxonomy}_exclude=
query parameter
This mirrors our existing support for ?{taxonomy}= filtering in the posts
controller (which allows querying for only records with are associated with
any of the provided term IDs for the specified taxonomy) by adding an
equivalent _exclude
variant to list IDs of terms for which associated posts
should NOT be returned.
(props @kadamwhite, #2756)
Use get_comment_type()
when comparing updating comment status.
Comments having a empty comment_type
within WordPress bites us again.
Fixes a bug where comments could not be updated because of bad comparison
logic.
(props @joehoyle, #2753)
BREAKING CHANGE: Fix Content-Disposition header parsing.
Allows regular form submissions from HTML forms, as well as properly formatted HTTP requests from clients. Note: this breaks backwards compatibility, as previously, the header parsing was completely wrong.
(props @rmccue, #2239)
BREAKING CHANGE: Use compact links for embedded responses if they are available.
Introduces curies for sites running WordPress 4.5 or greater; no changes for those running WordPress 4.4.
(props @joehoyle, #2412)
JavaScript client updates:
_.contains
me
endpointwp.api.loadPromise
so developers can ensure api load complete before using(props @adamsilverstein, #2403)
Only adds alternate link header for publicly viewable CPTs.
(props @bradyvercher, #2387)
Adds roles
param for GET /wp/v2/users
.
(props @BE-Webdesign, #2372)
Declares password
in user schema, but never displays it.
(props @danielbachhuber, #2386)
Permits edit
context for requests which can edit the user.
(props @danielbachhuber, #2383)
Adds rest_pre_insert_{$taxonomy}
filter for terms.
(props @kjbenk, #2377)
Supports taxonomy collection args on posts endpoint.
(props @joehoyle, #2287)
Removes post meta link from post response.
(props @joehoyle, #2288)
Registers description
attribute when registering args from schema.
(props @danielbachhuber, #2362)
Uses $comment
from the database with rest_insert_comment
action.
(props @danielbachhuber, #2349)
Removes unnecessary global variables from users controller.
(props @claudiosmweb, #2335)
Ensures GET /wp/v2/categories
with out of bounds offset doesn’t return results.
(props @danielbachhuber, #2313)
Adds top-level support for date queries on posts and comments.
Respects show_avatars
setting for comments.
(props @BE-Webdesign, #2271)

for terms-for-post for better performance.
(props @rmccue, #2257)
Ensures comments search is an empty string.
(props @rmccue, #2256)
If no title is provided in create attachment request or file metadata, falls back to filename.
(props @danielbachhuber, #2254)
Removes unused $img_url_basename
variable in attachments controller.
(props @danielbachhuber, #2250)
BREAKING CHANGE: Removes meta endpoints from primary plugin.
If your project depends on post meta endpoints, please install WP REST API Meta Endpoints. For the gory history of meta, read #1425 and linked issues. At this time, we recommend using register_rest_field()
to expose meta (docs).
(props @danielbachhuber, #2172)
BREAKING CHANGE: Returns original resource when deleting PTCU.
Now that all resources require the force
param, we don’t need to wrap delete responses with the trash
state.
(props @danielbachhuber, #2163)
BREAKING CHANGE: Uses roles
rather than role
in the Users controller.
Building the REST API gives us the opportunity to standardize on roles
, instead of having both roles
and role
.
(props @joehoyle, #2177)
BREAKING CHANGES: Moves to consistent use of context
throughout controllers.
Contexts limit the data present in the response. Here’s how to think of them: embed
correlates with sidebar representation, view
represents the primary public view, and edit
is the data expected for an editor.
(props @danielbachhuber, #2205, #2204, #2203, #2218, #2216, #2230, #2184, #2235)
BREAKING CHANGE: Removes post_*
query param support for GET /wp/v2/comments
.
The proper pattern is to use GET /wp/v2/posts
to fetch the post IDs to limit the request to.
(props @danielbachhuber, #2165)
BREAKING CHANGE: Introduces rest_validate_request_arg()
/rest_sanitize_request_arg()
.
Dedicated functions means we can use them for validating / sanitizing query args too. Removes WP_REST_Controller::validate_schema_property()
and WP_REST_Controller::sanitize_schema_property()
.
Requires minimum value of 1 for page
param.
(props @danielbachhuber, #2241)

Passes original $request context to prepare_items_query
.
(props @danielbachhuber, #2211)
Adds parent
and parent_exclude
params to GET Comments.
(props @danielbachhuber, #2206)
Enforces minimum 1 and maximum 100 values for per_page
parameter.
(props @danielbachhuber, #2209)
Adds author
and author_exclude
params to GET Posts and Comments.
Adds menu_order
param for GET
Pages; support menu_order
orderby.
(props @danielbachhuber, #2193)

when sanitizing type=string,format=email
.
(props @danielbachhuber, #2185)
Validates GET /wp/v2/comments
private query params.
Returns an error when user doesn’t have permission to use them, instead of silently discarding.
(props @danielbachhuber, #2178)
Explicitly prevents uploading attachments to other attachments or revisions.
(props @danielbachhuber, #2180)
Permits user urls to be edited through the API.
(props @danielbachhuber, #2182)
Marks all Status, Type and Taxonomy fields as readonly
.
(props @danielbachhuber, #2181)
Adds validation callbacks to collection query params.
Links taxonomy terms to the post type collections they support.

status to GET /wp/v2/statuses
.
(props @danielbachhuber, #2158)
Indicates when fields have HTML in schema.
(props @joehoyle, #2159)
Permits viewing of User who has published any Public posts.
(props @danielbachhuber, #2155)
Respects show_avatars
option when adding avatars to Users.
(props @nullvariable, #2151)
Controllers use $namespace
and $rest_base
class variables for easier subclassing.
(props @danielbachhuber, #2119, #2130, #2131, #2132, #2133, #2134, #2139, #2141, #2142)
BREAKING CHANGE: Moves Post->Term relations to the Post Resource
Previously, a client would fetch a Post’s Tags with GET /wp/v2/posts/<id>/tags
.
In Beta 11, an array of term ids is included on the Post resource.
The collection of terms for a Post can be fetched with GET /wp/v2/tags?post=<id>
.
The WP_REST_Posts_Terms_Controller
class no longer exists.
(props @joehoyle, #2063)
BREAKING CHANGE: Adds latest JS client including a minified version.
See pull request for a summarized changelog.
(props @adamsilverstein, #1981)
BREAKING CHANGE: Changes featured_image
attribute on Posts to featured_media
.
While featuring other attachment types isn’t yet officially supported, this makes it easier for us to introduce the possibility in the future.
(props @danielbachhuber, #2044)
BREAKING CHANGE: Uses discrete schema title for categories and tags.
If you’ve used register_rest_field( 'term' )
, you’ll need to change 'term'
to 'tag'
and/or 'category'
.
(props @danielbachhuber, #2005)
BREAKING CHANGE: Makes many filters dynamic based on the controller type.
If you were using the rest_prepare_term
filter, you’ll need to change it to rest_prepare_post_tag
or rest_prepare_category
.
If you were using rest_post_query
or rest_terms_query
, you’ll need update your use to rest_page_query
, etc.
If you were using rest_post_trashable
, rest_insert_post
or rest_delete_post
, they are now dynamic based on the post type slug.
Renames GET /wp/v2/comments
user
param to author
to match resource attribute.
Not a breaking change, because it didn’t work in the first place.
(props @danielbachhuber, #2105)
Adds support for GET /wp/v2/pages parent=1,2,3
.
(props @danielbachhuber, #2101)
Persists image metadata title and caption when not present in the request.
(props @danielbachhuber, #2079)
Add parent_exclude
param to GET /wp/v2/posts
.
(props @danielbachhuber, #2077)

.
(props @danielbachhuber, #2069)
Filter the responses by context after processing additional fields.
(props @danielbachhuber, #2067)
Adds offset
param support for collections of Posts, Users, Comments, and Taxonomy Terms.
Adds rest_insert_{$taxonomy}
and rest_delete_{$taxonomy}
actions.
(props @danielbachhuber, #2060)
Provides more helpful error message/code on Post Create/Update fail.
(props @danielbachhuber, #2053)
Forces GET /wp/v2/media
to be limited to 'status' => [ inherit, private, trash ]
(props @danielbachhuber, #2026)
Uses more correct error code for Comment::delete
permission check.
(props @danielbachhuber, #2054)
Calls prepare_item_for_response()
directly in create and update methods.
This lets us pass the original request through, giving the method and its filter genuine context, and avoids an
unnecessary call to get_item()
.
Moves permission check methods across controllers.
Placing them above the method they’re supposed to check makes the code more readable.
(props @danielbachhuber, #2030, #2029, #2034, #2036, #2037, #2035, #2039)
Requires force
argument for DELETE /wp/v2/<taxonomy>/<id>
.
(props @danielbachhuber, #2028)
Conditionally requires and defines REST API classes and functions.

Adds helpful description to force
param across all DELETE
registrations
In GET /wp/v2/<taxonomy>
, drops support for orderby=>term_id
.
Only one id
is exposed through the REST API.
(props @danielbachhuber, #1990)
SECURITY: Ensure media of private posts are private too.
Reported by @danielbachhuber on 2016-01-08.
BREAKING CHANGE: Removes compatibility repo for WordPress 4.3.
WordPress 4.4 is now the minimum supported WordPress version.
(props @danielbachhuber, #1848)
BREAKING CHANGE: Changes link relation for types and taxonomies.
In Beta 9, this link relation was introduced as item
, which isn’t correct. The relation has been changed to https://api.w.org/items
.
(props @danielbachhuber, #1853)
BREAKING CHANGE: Introduces edit
context for wp/v2/types
and wp/v2/taxonomies
.
Some fields have moved into this context, which require edit_posts
and manage_terms
, respectively.
BREAKING CHANGE: Removes post_format
as a term _link
for Posts.
Post formats aren’t a custom taxonomy in the eyes of the REST API.
(props @danielbachhuber, #1854)
Declares parent
query param for Pages.
(props @danielbachhuber, #1975)
Permits logged-in users to query for media.
(props @danielbachhuber, #1973)
Removes duplicated query params from Terms controller.

.
Ensures GET /wp/v2/posts
respects order
and orderby
params.
(props @danielbachhuber, #1962)
Fixes fatal by loading wp-admin/includes/user.php
to expose wp_delete_user()
.
(props @danielbachhuber, #1958)
Permits making a post sticky when also supplying an empty password.
(props @westonruter, #1949)
Uses WP_REST_Request
internally across controllers.
Cleans up permissions checks in WP_REST_Terms_Controller
.
(props @danielbachhuber, #1941)
Uses show_in_rest
to determine publicness for post types.
(props @danielbachhuber, #1942)
Makes description
strings available for translation.
(props @danielbachhuber, #1944)
Checks assign_terms
cap for taxonomy when managing post terms.
(props @danielbachhuber, #1940)
Defer to edit_posts
of the custom post type when accessing private query vars.

Permits creating comments without an assigned post.
(props @danielbachhuber, #1857)
Prevents error notice when show_in_rest
isn’t set for a post type.
(props @danielbachhuber, #1852)
BREAKING CHANGE: Move tags and categories to top-level endpoints.
Tags are now accessible at /wp/v2/tags
, and categories accessible at /wp/v2/categories
. Post terms reside at /wp/v2/posts/<id>/tags
and /wp/v2/<id>/categories
.
(props @danielbachhuber, #1802)
BREAKING CHANGE: Return object for requests to /wp/v2/taxonomies
.
This is consistent with /wp/v2/types
and /wp/v2/statuses
.
(props @danielbachhuber, #1825)
BREAKING CHANGE: Remove rest_get_timezone()
.
json_get_timezone() was only ever used in v1. This function causes fatals, and shouldn’t be used.
(props @danielbachhuber, #1823)
BREAKING CHANGE: Rename register_api_field()
to register_rest_field()
.
Introduces a register_api_field()
function for backwards compat, which calls _doing_it_wrong()
. However, register_api_field()
won’t ever be committed to WordPress core, so you should update your function calls.
(props @danielbachhuber, #1824)
BREAKING CHANGE: Change taxonomies’ post_type
argument to type
.
It’s consistent with how we’re exposing post types in the API.
(props @danielbachhuber, #1824)
Sync infrastructure with shipped in WordPress 4.4.
Change terms endpoints to use term_id
not tt_id
.
(props @joehoyle, #1837)
Standardize declaration of context
param for GET
requests across controllers.
However, we’re still inconsistent in which controllers expose which params. Follow #1845 for further discussion.
Link types / taxonomies to their collections, and vice versa.
Collections link to their type / taxonomy with the about
relation; types / taxonomies link to their colletion with the item
relation, which is imperfect and may change in the future.
Add missing ‘wp/v2’ in Location Response header when creating new Post Meta.
(props @johanmynhardt, #1790)
Expose Post collection query params, including author
, order
, orderby
and status
.
(props @danielbachhuber, #1793)
Ignore sticky posts by default.
(props @danielbachhuber, #1801)
Include full
image size in attachment sizes
attribute.
(props @danielbachhuber, #1806)
In text strings, use id
instead of ID
.
ID is an implementation artifact. Our Resources use id
.
(props @danielbachhuber, #1803)
Ensure attachment.sizes[]
use mime_type
instead of mime-type
.
(props @danielbachhuber, #1809)
Introduce rest_authorization_required_code()
.
Many controllers returned incorrect HTTP codes, which this also fixes.
(props @danielbachhuber, #1808)
Respect core’s comment_registration
setting.
If it’s enabled, require users to be logged in to comment.
(props @danielbachhuber, #1826)
Default to wildcard when searching users.

Set fields=>id
when using WP_User_Query
to fix large memory usage
(props @joehoyle, #1770)

(props @danielbachhuber, #1734)
Change link relations to use api.w.org.
(props @danielbachhuber, #1726)
Remove global inclusion of wp-admin/includes/admin.php
For a long time, the REST API loaded wp-admin/includes/admin.php to make use of specific admin utilities. Now, it only loads those admin utilities when it needs them.
If your custom endpoints make use of admin utilities, you’ll need to make sure to load wp-admin/includes/admin.php before you use them.
(props @joehoyle, #1696)
Link directly to the featured image in a Post’s links.
Provide object type as callback argument for custom API fields.
(props @jtsternberg, #1714)

For image attachments, media_details includes a sizes array of image sizes, which is useful for templating.
(props @danielbachhuber, #1667)
Make WP_REST_Controller
error messages more helpful by specifying method to subclass.
(props @danielbachhuber, #1670)
Expose slug
in embed
context for Users.
user_nicename is a public attribute, used in user URLs, so this is safe data to present.
(props @danielbachhuber, #1666)
Handle falsy value from wp_count_terms()
, fixing fatal.
(props @joehoyle, #1641)
Correct methods in WP_REST_SERVER::EDITABLE

(props @pento, #1499)
In WP_REST_Posts_Controller::update_item()
, check the post ID based on the proper post type.
(props @rachelbaker, #1497)
Load api-core as a compatibility library
Now api-core has been merged into WordPress trunk (for 4.4) we should no longer load the infrastructure code when it’s already available. This also fixes a fatal error for users who were on trunk.
(props @rmccue)
Switch to new mysql_to_rfc3339
(props @rmccue)
Double-check term taxonomy
(props @rmccue)
Load admin functions
This was removed from the latest beta of WordPress in the REST API infrastructure, a more long term fix is planned.
(props @joehoyle)
Add Add compat shim for renamed rest_mysql_to_rfc3339()
(props @danielbachhuber)
Compat shim for wp_is_numeric_array()
(props @danielbachhuber)
Revert Switch to register_post_type_args filter
(props @joehoyle)
Show public user information through the user controller.
In WordPress as of r32683 (scheduled for 4.3), WP_User_Query
now has support for getting users with published posts.
To match current behaviour in WordPress themes and feeds, we now expose this public user information. This includes the avatar, description, user ID, custom URL, display name, and URL, for users who have published at least one post on the site. This information is available to all clients; other fields and data for all users are still only available when authenticated.
Send schema in OPTIONS requests and index.
Rather than using separate /schema
endpoints, the schema for items is now available through an OPTIONS request to the route. This means that full documentation is now available for endpoints through an OPTIONS request; this includes available methods, what data you can pass to the endpoint, and the data you’ll get back.
This data is now also available in the main index and namespace indexes. Simply request the index with context=help
to get full schema data. Warning: this response will be huge. The schema for single endpoints is also available in the collection’s OPTIONS response.
⚠️ This breaks backwards compatibility for clients relying on schemas being at their own routes. These clients should instead send OPTIONS
requests.
Custom endpoints can register their own schema via the schema
option on the route. This option should live side-by-side with the endpoints (similar to relation
in WP’s meta queries), so your registration call will look something like:
`php
register_rest_route( ‘test-ns’, ‘/test’, array(
array(
‘methods’ => ‘GET’,
‘callback’ => ‘my_test_callback’,
),
‘schema’ => ‘my_schema_callback’,
) );
`
Update JavaScript API for version 2.
Our fantastic JavaScript API from version 1 is now available for version 2, refreshed with the latest and greatest changes.
As a refresher: if you want to use it, simply make your script depend on wp-api
when you enqueue it. If you want to enqueue the script manually, add wp_enqueue_script( 'wp-api' )
to a callback on wp_enqueue_scripts
.
Embed links inside items in a collection.
Previously when fetching a collection of items, you only received the items themselves. To fetch the links as well via embedding, you needed to make a request to the single item with _embed
set.
No longer! You can now request a collection with embeds enabled (try /wp/v2/posts?_embed
). This will embed links inside each item, allowing you to build interface items much easier (for example, post archive pages can get featured image data at the same time).
This also applies to custom endpoints. Any endpoint that returns a list of objects will automatically have the embedding applied to objects inside the list.
Fix potential XSS vulnerability.
Requests from other origins could potentially run code on the API domain, allowing cross-origin access to authentication cookies or similar.

Move /posts
WP_Query
vars back to filter
param.
In version 1, we had internal WP_Query
vars available via filter
(e.g. filter[s]=search+term
). For our first betas of version 2, we tried something different and exposed these directly on the endpoint. The experiment has now concluded; we didn’t like this that much, so filter
is back.
We plan on adding nicer looking arguments to collections in future releases, with a view towards being consistent across different collections. We also plan on opening up the underlying query vars via filter
for users, comments, and terms as well.
⚠️ This breaks backwards compatibility for users using WP Query vars. Simply change your x=y
parameter to filter[x]=y
.
(props @WP-API, #1420)
Respect rest_base
for taxonomies.
⚠️ This breaks backwards compatibility by changing the /wp/v2/posts/{id}/terms/post_tag
endpoint to /wp/v2/posts/{id}/tag
.
(props @joehoyle, #1466)
Add permission check for retrieving the posts collection in edit context.
By extension of the fact that getting any individual post yields a forbidden context error when the context=edit
and the user is not authorized, the user should also not be permitted to list any post items when unauthorized.
(props @danielpunkass, #1412)
Ensure the REST API URL always has a trailing slash.
Previously, when pretty permalinks were enabled, the API URL during autodiscovery looked like /wp-json
, whereas the non-pretty permalink URL looked like ?rest_route=/
. These are now consistent, and always end with a slash character to simplify client URL building.
Use wp_json_encode
instead of json_encode
Since WordPress 4.1, wp_json_encode
has been available to ensure encoded values are sane, and that non-UTF8 encodings are supported. We now use this function rather than doing the encode ourselves.
(props @rmccue, @pento, #1417)
Add role
to schema for users.
The available roles you can assign to a user are now available in the schema as an enum
.
(props @joehoyle, #1400)
Use the schema for validation inside the comments controller.
Previously, the schema was merely a decorative element for documentation inside the comments controller. To bring it inline with our other controllers, the schema is now used internally for validation.
(props @joehoyle, #1422)
Don’t set the Location header in update responses.
Previously, the Location header was sent when updating resources due to some inadvertent copypasta. This header should only be sent when creating to direct clients to the new resource, and isn’t required when you’re already on the correct resource.
(props @rachelbaker, #1441)
Re-enable the rest_insert_post
action hook for WP_REST_Posts_Controller
This was disabled during 2.0 development to avoid breaking lots of plugins on the json_insert_post
action. Now that we’ve changed namespaces and are Mostly Stable ™, we can re-enable the action.
Fix post taxonomy terms link URLs.
When moving the routes in a previous beta, we forgot to correct the links on post objects to the new correct route. Sorry!
Use wp_get_attachment_image_src()
on the image sizes in attachments.
Since the first versions of the API, we’ve been building attachment URLs via str_replace
. Who knows why we were doing this, but it caused problems with custom attachment URLs (such as CDN-hosted images). This now correctly uses the internal functions and filters.
(props @joehoyle, #1462)
Make the embed context a default, not forced.
If you want embeds to bring in full data rather than with context=edit
, you can now change the link to specify context=view
explicitly.
(props @rmccue, #1464)
Ensure we always use the term_taxonomy_id
and never expose term_id
publicly.
Previously, term_id
was inadvertently exposed in some error responses.
(props @jdolan, #1430)
Fix adding alt text to attachments on creation.
Previously, this could only be set when updating an attachment, not when creating one.
(props @joehoyle, #1398)
Throw an error when registering routes without a namespace.
Namespaces should always be provided when registering routes. We now throw a doing_it_wrong
error when attempting to register one. (Previously, this caused a warning, or an invalid internal route.)
If you really need to register namespaceless routes (e.g. to replicate an existing API), call WP_REST_Server::register_route
directly rather than using the convenience function.
(props @joehoyle, @rmccue, #1355)
Show links on embeds.
Previously, links were accidentally stripped from embedded response data.
(props @rmccue, #1472)
Clarify insufficient permisssion error when editing posts.
(props @danielpunkass, #1411)
Improve @return inline docs for rest_ensure_response()

Check taxonomies exist before trying to set properties.
(props @joehoyle, @rachelbaker, #1354)
Update controllers to ensure we use sanitize_callback
wherever possible.
(props @joehoyle, #1399)
Add more phpDoc documentation, and correct existing documentation.
Update testing infrastructure.
Travis now runs our coding standards tests in parallel, and now uses the new, faster container-based testing infrastructure.
Add ability to declare sanitization and default options for schema fields.
The arg_options
array can be used to declare the sanitization callback,
default value, or requirement of a field.
Expand supported parameters for creating and updating Comments.
(props @rachelbaker, #1245)
Declare collection parameters for Terms of a Post.
Define the available collection parameters in get_collection_params()
and
allow Terms of a Post to be queried by term order.

Improve the Attachment error message for an invalid Content-Disposition
(props @danielbachhuber, #1317)
Return 200 status when updating Attachments, Comments, and Users.

for making REST requests internally.
(props @danielbachhuber, #1333)
Remove unused DateTime class.
(props @rmccue, #1314)
Add inline documentation for $wp_rest_server
global.
(props @Shelob9, #1324)
Load the WP REST API before the main query runs.
The rest_api_loaded
function now hooks into the parse_request
action.
This change prevents the main query from being run on every request and
allows sites to set WP_USE_THEMES
to false
. Previously, the main query
was always being run (SELECT * FROM wp_posts LIMIT 10
), even though the
result was never used and couldn’t be cached.
(props @rmccue, #1270)
Register a new field on an existing WordPress object type.
Introduces register_api_field()
to add a field to an object and
its schema.

Add endpoints for viewing, creating, updating, and deleting Terms for a Post.
The new WP_REST_Posts_Terms_Controller
class controller supports routes for
Terms that belong to a Post.
(props @joehoyle, @danielbachhuber, #1216)
Add pagination headers for collection queries.
The X-WP-Total
and X-WP-TotalPages
are now present in terms, comments,
and users collection responses.
(props @danielbachhuber, #1182)
(props @danielbachhuber, #1191)
(props @danielbachhuber, @joehoyle, #1197)
List registered namespaces in the index for feature detection.
The index (/wp-json
by default) now contains a list of the available
namespaces. This allows for simple feature detection. You can grab the index
and check namespaces for wp/v3
or pluginname/v2
, which indicate the
supported endpoints on the site.
(props @rmccue,, #1283)
Standardize link property relations and support embedding for all resources.
Change link properties to use IANA-registered relations. Also adds embedding
support to Attachments, Comments and Terms.
(props @rmccue, @rachelbaker, #1284)
Add support for Composer dependency management.
Allows you to recursively install/update the WP REST API inside of WordPress
plugins or themes.
(props @QWp6t, #1157)
Return full objects in the delete response.
Instead of returning a random message when deleting a Post, Comment, Term, or
User provide the original resource data.
(props @danielbachhuber, #1253)
(props @danielbachhuber, #1254)
(props @danielbachhuber, #1255)
(props @danielbachhuber, #1256)
Return programmatically readable error messages for invalid or missing
required parameters.
(props @joehoyle, #1175)
Declare supported arguments for Comment and User collection queries.
(props @danielbachhuber, #1211)
(props @danielbachhuber, #1217)
Automatically validate parameters based on Schema data.

(props @rachelbaker, #1267)
Add link properties to the Post Status response.
(props @joehoyle, #1243)
Return 0
for parent
in Post response instead of null
.
(props @danielbachhuber, #1269)
Only link author
when there’s a valid author
(props @danielbachhuber, #1203)
Only permit querying by parent term when tax is hierarchical.
(props @danielbachhuber, #1219)
Only permit deleting posts of the proper type
(props @danielbachhuber, #1257)
Set pagination headers even when no found posts.
(props @danielbachhuber, #1209)
Correct prefix in rest_request_parameter_order
filter.
(props @quasel, #1158)
