Documentation

For more details visit Coinbase API docs.

To start using library, you'll need to create a Coinbase Commmerce account. Once you've created your Coinbase Commerce account, create an API_KEY in Settings.

Next create a Client object for interacting with the API:

require'coinbase_commerce'API_KEY="API KEY"client=CoinbaseCommerce::Client.new(api_key: API_KEY)

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

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

client.charge.createclient.checkout.auto_pagingclient.event.listclient.charge.retrieveclient.checkout.modify

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

checkout=client.checkout.retrieve<id>checkout.refreshcheckout.savecheckout.delete

Each API method returns an APIObject representing the JSON response from the API, all of the models support hash and JSON representation.
Also when the response data is parsed into Ruby 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.

The client supports handling of common API errors and warnings. All errors occuring during the interaction with the API will be raised as exceptions.

Validating webhook signatures

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