Wordpress API - Python Client

A Python wrapper for the Wordpress and WooCommerce REST APIs with oAuth1a 3leg support.

Supports the Wordpress REST API v1-2, WooCommerce REST API v1-3 and WooCommerce WP-API v1-2 (with automatic OAuth3a handling). Forked from the excellent WooCommerce API written by Claudio Sanches and modified to work with Wordpress: https://github.com/woocommerce/wc-api-python

I created this fork because I prefer the way that the wc-api-python client interfaces with the Wordpress API compared to the existing python client, https://pypi.python.org/pypi/wordpress_json which does not support OAuth authentication, only Basic Authentication (very unsecure)

Any comments about how you're using the API and suggestions about how this repository could be improved are welcome :). You can find my contact info in my GitHub profile.

Roadmap

• [x] Create initial fork
• [x] Implement 3-legged OAuth on Wordpress client
• [x] Better local storage of OAuth credentials to stop unnecessary API keys being generated
• [x] Support image upload to WC Api
• [ ] Better handling of timeouts with a back-off
• [ ] Implement iterator for convenient access to API items

Requirements

Wordpress version 4.7+ comes pre-installed with REST API v2, so you don't need to have the WP REST API plugin if you have the latest Wordpress.

You should have the following plugins installed on your wordpress site:

• WP REST API (only required for WP < v4.7, recommended version: 2.0+)
• WP REST API - OAuth 1.0a Server (optional, if you want oauth within the wordpress API. https://github.com/WP-API/OAuth1)
• WP REST API - Meta Endpoints (optional)
• WooCommerce (optional, if you want to use the WooCommerce API)

The following python packages are also used by the package

• requests
• beautifulsoup

Installation

Install with pip

pip install wordpress-api

Download this repo and use setuptools to install the package

pip install setuptools
git clone https://github.com/derwentx/wp-api-python
python setup.py install

Testing

If you have installed from source, then you can test with unittest:

pip install -r requirements-test.txt
python -m unittest -v tests

Getting started

Generate API credentials (Consumer Key & Consumer Secret) following these instructions: http://v2.wp-api.org/guide/authentication/

Simply go to Users -> Applications and create an Application, e.g. "REST API". Enter a callback URL that you will be able to remember later such as "http://example.com/oauth1_callback" (not really important for this client). Store the resulting Key and Secret somewhere safe.

Check out the Wordpress API endpoints and data that can be manipulated in http://v2.wp-api.org/reference/.

Setup

Wordpress API with Basic authentication:

(Note: requires Basic Authentication plugin)

from wordpress import API

wpapi = API(
    url="http://example.com",
    api="wp-json",
    version='wp/v2',
    wp_user="XXXX",
    wp_pass="XXXX",
    basic_auth = True,
    user_auth = True,
)

WP REST API v2:

(Note: the username and password are required so that it can fill out the oauth request token form automatically for you. Requires OAuth 1.0a plugin. )

#...

wpapi = API(
    url="http://example.com",
    consumer_key="XXXXXXXXXXXX",
    consumer_secret="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    api="wp-json",
    version="wp/v2",
    wp_user="XXXX",
    wp_pass="XXXX",
    oauth1a_3leg=True,
    creds_store="~/.wc-api-creds.json"
)

Legacy WooCommerce API v3:

#...

wcapi = API(
    url="http://example.com",
    consumer_key="ck_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    consumer_secret="cs_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    api="wc-api",
    version="v3"
)

New WC REST API:

Note: oauth1a 3legged works with Wordpress but not with WooCommerce. However oauth1a signing still works. If you try to do oauth1a_3leg with WooCommerce it just says "consumer_key not valid", even if it is valid.

#...

wcapi = API(
    url="http://example.com",
    consumer_key="ck_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    consumer_secret="cs_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    api="wp-json",
    version="wc/v2",
    callback='http://127.0.0.1/oauth1_callback'
)

Options

Option	Type	Required	Description
url	string	yes	Your Store URL, example: http://wp.dev/
consumerKey	string	yes	Your API consumer key
consumerSecret	string	yes	Your API consumer secret
api	string	no	Determines which api to use, defaults to wp-json, can be arbitrary: wc-api, oembed
version	string	no	API version, default is wp/v2, can be v3 or wc/v1 if using wc-api
timeout	integer	no	Connection timeout, default is 5
verify_ssl	bool	no	Verify SSL when connect, use this option as False when need to test with self-signed certificates
basic_auth	bool	no	Force Basic Authentication, can be through query string or headers (default)
query_string_auth	bool	no	Use query string for Basic Authentication when True and using HTTPS, default is False which uses header
oauth1a_3leg	string	no	use oauth1a 3-legged authentication
creds_store	string	no	JSON file where oauth verifier is stored (only used with OAuth_3Leg)

Methods

Params	Type	Description
endpoint	string	API endpoint, example: posts or user/12
data	dictionary	Data that will be converted to JSON

GET

• .get(endpoint)

POST

• .post(endpoint, data)

PUT

• .put(endpoint, data)

DELETE

• .delete(endpoint)

OPTIONS

• .options(endpoint)

Upload an image

(Note: this only works on WP API with basic auth)

assert os.path.exists(img_path), "img should exist"
data = open(img_path, 'rb').read()
filename = os.path.basename(img_path)
_, extension = os.path.splitext(filename)
headers = {
    'cache-control': 'no-cache',
    'content-disposition': 'attachment; filename=%s' % filename,
    'content-type': 'image/%s' % extension
}
return wcapi.post(self.endpoint_singular, data, headers=headers)

Response

All methods will return Response object.

Example of returned data:

>>> from wordpress import api as wpapi
>>> r = wpapi.get("posts")
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=UTF-8'
>>> r.encoding
'UTF-8'
>>> r.text
u'{"posts":[{"title":"Flying Ninja","id":70,...' // Json text
>>> r.json()
{u'posts': [{u'sold_individually': False,... // Dictionary data

A note on DELETE requests.

The extra keyword arguments passed to the function of a __request call (such as .delete()) to a wordpress.API object are used to modify a Requests.request call, this is to allow you to specify custom parameters to modify how the request is made such as headers. At the moment it only passes the headers parameter to requests, but if I see a use case for it, I can forward more of the parameters to Requests. The delete function doesn’t accept a data object because a HTTP DELETE request does not typically have a payload, and some implementations of a HTTP server would reject a DELETE request that has a payload. You can still pass api request parameters in the query string of the URL. I would suggest using a library like urlparse / urllib.parse to modify the query string if you are automatically deleting users. According the the [documentation](https://developer.wordpress.org/rest-api/reference/users/#delete-a-user) for deleting a user, you need to pass the force and reassign parameters to the API, which can be done by appending them to the endpoint URL. .. code-block:: python

>>> response = wpapi.delete(‘/users/<Id>?reassign=<other_id>&force=true’)
>>> response.json()
{“deleted”:true, ... }
