Introduction

WooCommerce (WC) 2.6+ is fully integrated with the WordPress REST API. This allows WC data to be created, read, updated, and deleted using requests in JSON format and using WordPress REST API Authentication methods and standard HTTP verbs which are understood by most HTTP clients.

The current WP REST API integration version is v2 which takes a first-order position in endpoints.

The following table shows API versions present in each major version of WooCommerce:

API Version	WC Version	WP Version	Documentation
v2	3.0.x or later	4.4 or later	-
v1	2.6.x or later	4.4 or later	v1 docs

Prior to 2.6, WooCommerce had a REST API separate from WordPress which is now known as the legacy API. You can find the documentation for the legacy API separately.

API Version	WC Version	WP Version	Documentation
Legacy v3	2.4.x or later	4.1 or later	Legacy v3 docs
Legacy v2	2.2.x or later	4.1 or later	Legacy v2 docs
Legacy v1	2.1.x or later	4.1 or later	Legacy v1 docs

Requirements

To use the latest version of the REST API you must be using:

• WooCommerce 2.6+.
• WordPress 4.4+.
• Pretty permalinks in Settings > Permalinks so that the custom endpoints are supported. Default permalinks will not work.
• You may access the API over either HTTP or HTTPS, but HTTPS is recommended where possible.

If you use ModSecurity and see 501 Method Not Implemented errors, see this issue for details.

Please note that you are not required to install the WP REST API (WP API) plugin.

Request/Response Format

The default response format is JSON. Requests with a message-body use plain JSON to set or update resource attributes. Successful requests will return a 200 OK HTTP status.

Some general information about responses:

• Dates are returned in ISO8601 format: YYYY-MM-DDTHH:MM:SS
• Resource IDs are returned as integers.
• Any decimal monetary amount, such as prices or totals, will be returned as strings with two decimal places.
• Other amounts, such as item counts, are returned as integers.
• Blank fields are generally included as null or emtpy string instead of being omitted.

JSONP Support

The WP REST API supports JSONP by default. JSONP responses use the application/javascript content-type. You can specify the callback using the ?_jsonp parameter for GET requests to have the response wrapped in a JSON function:

GET

/wp-json/wc/v2?_jsonp=callback

curl https://example.com/wp-json/wc/v2/products/tags/34?_jsonp=tagDetails \
	-u consumer_key:consumer_secret

WooCommerce.get("products/tags/34?_jsonp=tagDetails")
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.log(error.response.data);
  });

<?php print_r($woocommerce->get('products/tags/34', ['_jsonp' => 'tagDetails'])); ?>

print(wcapi.get("products/tags/34?_jsonp=tagDetails").json())

woocommerce.get("products/tags/34", _jsonp: "tagDetails").parsed_response

Response:

/**/tagDetails({"id":34,"name":"Leather Shoes","slug":"leather-shoes","description":"","count":0,"_links":{"self":[{"href":"https://example.com/wp-json/wc/v2/products/tags/34"}],"collection":[{"href":"https://example.com/wp-json/wc/v2/products/tags"}]}})%

Errors

Occasionally you might encounter errors when accessing the REST API. There are four possible types:

Error Code	Error Type
400 Bad Request	Invalid request, e.g. using an unsupported HTTP method
401 Unauthorized	Authentication or permission error, e.g. incorrect API keys
404 Not Found	Requests to resources that don't exist or are missing
500 Internal Server Error	Server error

WP REST API error example:

{
  "code": "rest_no_route",
  "message": "No route was found matching the URL and request method",
  "data": {
    "status": 404
  }
}

WooCommerce REST API error example:

{
  "code": "woocommerce_rest_term_invalid",
  "message": "Resource doesn't exist.",
  "data": {
    "status": 404
  }
}

Errors return both an appropriate HTTP status code and response object which contains a code, message and data attribute.

Parameters

Almost all endpoints accept optional parameters which can be passed as a HTTP query string parameter, e.g. GET /orders?status=completed. All parameters are documented along each endpoint.

Pagination

Requests that return multiple items will be paginated to 10 items by default. This default can be changed by the site administrator by changing the posts_per_page option. Alternatively the items per page can be specified with the ?per_page parameter:

GET /orders?per_page=15

You can specify further pages with the ?page parameter:

GET /orders?page=2

You may also specify the offset from the first resource using the ?offset parameter:

GET /orders?offset=5

Page number is 1-based and omitting the ?page parameter will return the first page.

The total number of resources and pages are always included in the X-WP-Total and X-WP-TotalPages HTTP headers.

Link Header

Pagination info is included in the Link Header. It's recommended that you follow these values instead of building your own URLs where possible.

Link: <https://www.example.com/wp-json/wc/v2/products?page=2>; rel="next",
<https://www.example.com/wp-json/wc/v2/products?page=3>; rel="last"`

The possible rel values are:

Value	Description
next	Shows the URL of the immediate next page of results.
last	Shows the URL of the last page of results.
first	Shows the URL of the first page of results.
prev	Shows the URL of the immediate previous page of results.
