Introduction

The PHP examples in this documentation will assume you are using the WooCommerce client from Automattic to connect to the WooCommerce REST API, which you can require in your project via Composer:

$ composer require automattic/woocommerce

You will then need to configure and instantiate the client in your project, like so:

<?php

require __DIR__ . '/vendor/autoload.php';

use Automattic\WooCommerce\Client;

$woocommerce = new Client(
    'http://example.com',    // Your store URL
    'consumer_key',          // Your consumer key
    'consumer_secret',       // Your consumer secret
    [
        'wp_api'  => true,   // Enable the WP REST API integration
        'version' => 'wc/v3' // WooCommerce WP REST API version
    ]
);

?>

Welcome to the WooCommerce Memberships REST API documentation!

Since version 1.11.0, Memberships extends WooCommerce and builds upon the WordPress REST API to handle user memberships and memberships plans data through robust REST API endpoints.

Memberships currently supports v2 and v3 (added in 1.12.0) of the WooCommerce REST API extension for WordPress. All its endpoints will be added to the /wc/v2/ and /wc/v3/ routes.

This documentation showcases the available HTTP API methods and endpoints to perform valid requests, along with some examples in PHP.

If you spot a typo, an error, have a question, want to provide feedback or extend the documentation, please refer to the GitHub repository of this documentation.

Authentication

HTTP Basic Auth example:

<?php

require __DIR__ . '/vendor/autoload.php';

use Automattic\WooCommerce\Client;

$woocommerce = new Client(
    'https://example.com',
    'consumer_key',
    'consumer_secret',
    [
        'wp_api' => true,
        'version' => 'wc/v3'
    ]
);

?>

Occasionally, some servers may not parse the Authorization header correctly.

If you see a "Consumer key is missing" error when authenticating over SSL, likely you have a server issue. 

In this case, you may provide the consumer key/secret as query string parameters instead.

Example for servers that not properly parse the Authorization header:

<?php

require __DIR__ . '/vendor/autoload.php';

use Automattic\WooCommerce\Client;

$woocommerce = new Client(
    'https://example.com',
    'consumer_key',
    'consumer_secret',
    [
        'wp_api' => true,
        'version' => 'wc/v3',
        // Force Basic Authentication as query string true and using under HTTPS
        'query_string_auth' => true 
    ]
);

?>

Since Memberships REST API is built on top of the WordPress REST API and requires WooCommerce to function, authorization for performing HTTP requests successfully is handled by WooCommerce and WordPress.

WooCommerce includes two ways to authenticate with the WP REST API. It is also possible to authenticate using any WP REST API authentication plugin or method.

Follow instructions from the WooCommerce core REST API Authentication chapter for authentication guidelines.

Discovery

Available Routes

/memberships

The memberships root endpoint lists all routes, along with supported HTTP methods for each, made available by WooCommerce Memberships.

HTTP REQUEST

GET http://example.com/wp-json/wc/v3/memberships

User Memberships

The User Membership

A user membership is created when a customer gets access to a membership plan, therefore all user memberships are linked to one user and one membership plan only. Also, a membership has a status and a start date.

Data Structure

A user membership has the following data structure in the REST API:

Property	Type	Description
`id`	`int`	`read-only` The unique identifier (integer) of the user membership.
`customer_id`	`int`	The unique identifier (integer) of the customer that owns the membership.
`plan_id`	`int`	The unique identifier (integer) of the membership plan the membership is for.
`status`	`string`	The current status (string) of the user membership.
`order_id`	`int\|null`	The unique identifier (integer) of the order that may have granted access to the matching membership plan. If the user membership is not linked to an order, it will return `null`.
`product_id`	`int\|null`	The unique identifier (integer) of a product that may have granted access to the matching membership plan. If the user membership is not linked to a product, it will return `null`.
`subscription_id`	`int\|null`	The unique identifier (integer) of a subscription that may be linked to the user membership. This property will exist only if the site is running WooCommerce Subscriptions alongside with Memberships. If there is no link to a subscription, the value will be `null`.¹
`date_created`	`datetime`	`read-only` The date (in Atom format) when the user membership object was created, in the local timezone. This does not necessarily match with the start date.
`date_created_gmt`	`datetime`	`read-only` The date (in Atom format) when the user membership object was created, in UTC. This does not necessarily match with the start date.
`start_date`	`datetime`	`read-only` The date (in Atom format) when the membership starts, in the local timezone.
`start_date_gmt`	`datetime`	The date (in Atom format) when the membership starts, in UTC.
`end_date`	`datetime\|null`	`read-only` The date (in Atom format) when the ends, in the local timezone. This is `null` if the membership doesn't have an end date.
`end_date_gmt`	`datetime\|null`	The date (in Atom format) when the ends, in UTC. This is `null` if the membership doesn't have an end date.
`paused_date`	`datetime\|null`	`read-only` The date (in Atom format) when the membership was last paused, in the local timezone. This is `null` if the membership was never paused. The value is not removed if the membership changes status.
`paused_date_gmt`	`datetime\|null`	`read-only` The date (in Atom format) when the membership was last paused, in UTC. This is `null` if the membership was never paused. The value is not removed if the membership changes status.
`cancelled_date`	`datetime\|null`	The date (in Atom format) when the membership was cancelled, in the local timezone. This is `null` if the membership was not cancelled.
`cancelled_date_gmt`	`datetime\|null`	The date (in Atom format) when the membership was cancelled, in UTC. This is `null` if the membership was not cancelled.
`view_url`	`string`	`read-only` URL pointing to the site's Members Area accessible to the membership's owner.
`profile_fields`	`array\|object`	Holds any profile fields set on the membership. Each array item has a "slug" `(string)` and a "value" (either a `boolean`, an `integer`, `float`, `string`, or `array`).
`meta_data`	`array\|object`	Holds any WordPress meta data set on the membership. Each array item has an "id" `(integer)`, a "key" `(string)` and a "value" (either a `boolean`, an `integer`, or `string`, which could also represent serialized data).
`_links`	`array`	`read-only` An array of items linking to related objects accessible through the REST API.

Notes:

¹ If WooCommerce Subscriptions is inactive this field will not exist.

`subcription_access_length`	`int\|null`	When access to the plan is tied to a subscription, the length in seconds that a corresponding user membership will have. This could be null if it lasts as long as the subscription is active or the plan does not have a subscription product that can grant access.¹
