Python Version

Python 2.7+ and 3.4+ are supported and tested.

Third Party Libraries and Dependencies

The following libraries will be installed when you install the client library:

• requests

Documentation

For more details visit Coinbase API docs.

To start using library, you need to register on Commerce SignUp. And get your API_KEY from user settings.

Next create a Client object for interacting with the API:

from coinbase_commerce.client import Client

API_KEY = "API KEY"
client = Client(api_key=API_KEY)

Client contains links to an every Python Class representations of the API resources Checkout, Charge, Event

You can call list, list_paging_iter, create, retrieve, modify methods from an API resource classes

client.charge.create
client.checkout.list_paging_iter 
client.event.list
client.charge.retrieve
client.checkout.modify

as well as save, delete, refresh methods from API resource class instances.

checkout = client.checkout.retrieve(<id>)
checkout.refresh()
checkout.save()
checkout.delete()

Each API method returns an APIObject (a subclass of dict) representing the JSON response from the API, all of the models are dumpable with JSON.
Also when the response data is parsed into Python objects, the appropriate APIObject subclasses will be used automatically. All subclasses of APIResource class support refresh method. This will update their attributes and all nested data by making a fresh GET request to the relevant API endpoint.

Client support Common API Errors and Warnings handling. All errors occuring during interaction with the API will be raised as exceptions.

Error	Status Code
APIError	*
InvalidRequestError	400
ParamRequiredError	400
ValidationError	400
AuthenticationError	401
ResourceNotFoundError	404
RateLimitExceededError	429
InternalServerError	500
ServiceUnavailableError	503

Validating webhook signatures

You could verify webhook signatures using our library. To perform the verification you'll need to provide the event data, a webhook signature from request header, and the endpoint’s secret. In case of invalid request signature or request payload, you will receive appropriate error message.

WEBHOOK_SECRET = 'your_webhook_secret'

# using Flask
@app.route('/webhooks', methods=['POST'])
def webhooks():
    # event payload
    request_data = request.data.decode('utf-8')
    # webhook signature
    request_sig = request.headers.get('X-CC-Webhook-Signature', None)

    try:
        # signature verification and event object construction
        event = Webhook.construct_event(request_data, request_sig, WEBHOOK_SECRET)
    except (WebhookInvalidPayload, SignatureVerificationError) as e:
        return str(e), 400

    print("Received event: id={id}, type={type}".format(id=event.id, type=event.type))
    return 'success', 200

Testing and Contributing

Any and all contributions are welcome! The process is simple: fork this repo, make your changes, run the test suite, and submit a pull request. Tests are run via nosetest. To run the tests, clone the repository and then:

Install the requirements

pip install -r requirements.txt

Run the tests for your current version of Python

Use tox to run the test suite against multiple versions of Python. You can install tox with pip or easy_install:

pip install tox
easy_install tox

Tox requires the appropriate Python interpreters to run the tests in different environments. We recommend using pyenv for this. Once you've installed the appropriate interpreters, running the tests in every environment is simple:

tox
