bigcommerce 0.20.0

Connect Python applications with the Bigcommerce API

Wrapper over the requests library for communicating with the Bigcommerce v2 API.

Install with pip install bigcommerce or easy_install bigcommerce. Tested with python 2.7.7+ and 3.4, and only requires requests and pyjwt.

Usage

Connecting

import bigcommerce

# Public apps (OAuth)
# Access_token is optional, if you don't have one you can use oauth_fetch_token (see below)
api = bigcommerce.api.BigcommerceApi(client_id='', store_hash='', access_token='')

# Private apps (Basic Auth)
api = bigcommerce.api.BigcommerceApi(host='store.mybigcommerce.com', basic_auth=('username', 'api token'))

BigcommerceApi also provides two helper methods for connection with OAuth2:

• api.oauth_fetch_token(client_secret, code, context, scope, redirect_uri) – fetches and returns an access token for your application. As a side effect, configures api to be ready for use.

• BigcommerceApi.oauth_verify_payload(signed_payload, client_secret) – Returns user data from a signed payload.

Accessing and objects

The api object provides access to each API resource, each of which provides CRUD operations, depending on capabilities of the resource:

api.Products.all()                         # GET /products (returns only a single page of products as a list)
api.Products.iterall()                     # GET /products (autopaging generator that yields all
                                           #                  products from all pages product by product.)
api.Products.get(1)                        # GET /products/1
api.Products.create(name='', type='', ...) # POST /products
api.Products.get(1).update(price='199.90') # PUT /products/1
api.Products.delete_all()                  # DELETE /products
api.Products.get(1).delete()               # DELETE /products/1
api.Products.count()                       # GET /products/count

The client provides full access to subresources, both as independent resources:

api.ProductOptions.get(1)                  # GET /products/1/options
api.ProductOptions.get(1, 2)               # GET /products/1/options/2

And as helper methods on the parent resource:

api.Products.get(1).options()              # GET /products/1/options
api.Products.get(1).options(1)             # GET /products/1/options/1

These subresources implement CRUD methods in exactly the same way as regular resources:

api.Products.get(1).options(1).delete()

Filters

Filters can be applied to all methods as keyword arguments:

customer = api.Customers.all(first_name='John', last_name='Smith')[0]
orders = api.Orders.all(customer_id=customer.id)

Error handling

Minimal validation of data is performed by the client, instead deferring this to the server. A HttpException will be raised for any unusual status code:

• 3xx status code: RedirectionException

• 4xx status code: ClientRequestException

• 5xx status code: ServerException

The low level API

The high level API provided by bigcommerce.api.BigcommerceApi is a wrapper around a lower level api in bigcommerce.connection. This can be accessed through api.connection, and provides helper methods for get/post/put/delete operations.

Managing OAuth Rate Limits

You can optionally pass a rate_limiting_management object into bigcommerce.api.BigcommerceApi or bigcommerce.connection.OAuthConnection for automatic rate limiting management, ex:

import bigcommerce

api = bigcommerce.api.BigcommerceApi(client_id='', store_hash='', access_token=''
                                     rate_limiting_management= {'min_requests_remaining':2,
                                                                'wait':True,
                                                                'callback_function':None})

min_requests_remaining will determine the number of requests remaining in the rate limiting window which will invoke the management function

wait determines whether or not we should automatically sleep until the end of the window

callback_function is a function to run when the rate limiting management function fires. It will be invoked after the wait, if enabled.

callback_args is an optional parameter which is a dictionary passed as an argument to the callback function.

For simple applications which run API requests in serial (and aren’t interacting with many different stores, or use a separate worker for each store) the simple sleep function may work well enough for most purposes. For more complex applications that may be parallelizing API requests on a given store, it’s adviseable to write your own callback function for handling the rate limiting, use a min_requests_remaining higher than your concurrency, and not use the default wait function.

To do

• Automatic enumeration of multiple page responses for subresources.
