Developers use the WordPress.com API to build external apps and integrate WordPress.com site content into a wide variety of external platforms.
WordPress.com REST API #
All WordPress.com sites, including VIP sites, feature the WordPress.com REST API. This is the recommended API for all integrations and features methods for handling posts, users, categories, tags and much more. Authentication is handled using OAuth2. A great way to begin exploring the REST API is to check out the developer console.
The VIP site theme loads for a REST API request to your site, which means custom post types, custom taxonomies, and custom user roles are there.
However, please note that due to the way theme loading is implemented, the theme only loads on single site endpoints (URLs like
/sites/:site/*), not multi-site endpoints.
REST API specific filters like
rest_api_allowed_post_types are in effect. Please be careful of theme constants like
TEMPLATEPATH as they’re not available in the REST API context.
WordPress REST API #
All WordPress.com VIP sites also feature the REST API infrastructure included in WordPress since version 4.4. This allows you to build your own API endpoints on your site, or you can enable the WP-API plugin and use the endpoints defined there.
Like the WordPress.com REST API, WordPress.com VIP supports OAuth2 authentication. Standard WordPress cookie+nonce authentication is also available, but this should only be used for features that run within the site itself.
A couple of important notes to keep in mind when developing against this API framework:
- While the WordPress.com API serves all requests from
https://public-api.wordpress.com/rest/…, WP REST API requests are served from your site’s domain:
- OAuth2 authentication is only available over HTTPS. Please use HTTPS for all API communication.
All WordPress.com sites, including VIP sites, also have an XML-RPC endpoint enabled at
/xmlrpc.php. Though it is required by certain legacy apps, we strongly urge the use of the REST API for all new development. Additional information on XML-RPC support is available here and here.
Note: XML-RPC requests that lack a user agent are blocked on WordPress.com.
Can REST or XML-RPC be disabled? #
No. These are enabled and secure for all WordPress.com sites, including VIP sites.
