CoinbaseCommerce

CoinbaseCommerce is an API wrapper for CoinbaseCommerce's APIs.

Installation

Add this line to your application's Gemfile:

gem 'coinbase_commerce'

And then execute:

$ bundle

Or install it yourself as:

$ gem install coinbase_commerce

Usage

You can create an instance of the API wrapper:

coinbase_commerce = CoinbaseCommerce::API.new("your_api_key")

You can set api_key, timeout, throws_exceptions, retry_if_fails and logger globally:

CoinbaseCommerce::API.api_key = "your_api_key"
CoinbaseCommerce::API.timeout = 15
CoinbaseCommerce::API.throws_exceptions = false
CoinbaseCommerce::API.retry_if_fails = true
CoinbaseCommerce::API.logger = Logger.new("#{Rails.root}/log/coinbase_commerce.log")

You can set webhook shared_secret to verify the webhooks. CoinbaseCommerce::Webhook.shared_secret = "your_shared_secret"

For example, you could set the values above in an initializer file in your Rails app (e.g. your_app/config/initializers/coinbase_commerce.rb).

Assuming you've set an api_key on CoinbaseCommerce, you can conveniently make API calls on the class itself:

CoinbaseCommerce::API.checkouts.all

You can also set the environment variable COINBASE_COMMERCE_API_KEY and CoinbaseCommerce will use it when you create an instance:

coinbase_commerce = CoinbaseCommerce::API.new

Fetching Checkouts

For example, to fetch all the checkouts of your account:

checkouts = coinbase_commerce.checkouts.all

Fetching Charges

Similarly, to fetch your charges:

lists = coinbase_commerce.charges.all

Or, to fetch a checkout by id:

checkout = coinbase_commerce.checkouts.find('checkout_id')

Or, to delete a checkout by id:

checkout = coinbase_commerce.checkouts.delete('checkout_id')

Or, to update a checkout by id:

checkout = coinbase_commerce.checkouts.update(id: 'checkout_id', name: 'Updated name')

passing id to update any resource is necessory

The above examples were for only checkout resource. Same way it can be used for other resources i.e. charges, events etc.

To verify a webhook request you can simply check in a before_action

begin
  CoinbaseCommerce::Webhook.verify(request)
rescue CoinbaseCommerce::CoinbaseCommerceError => e
  # do something 
end

Setting timeouts

CoinbaseCommerce defaults to a 30 second timeout. You can optionally set your own timeout (in seconds) like so:

coinbase_commerce = CoinbaseCommerce::API.new("your_api_key", {:timeout => 5})

or

coinbase_commerce.timeout = 5

Error handling

By default CoinbaseCommerce will attempt to raise errors returned by the API automatically.

If you set the throws_exceptions boolean attribute to false, for a given instance, then CoinbaseCommerce will not raise exceptions. This allows you to handle errors manually. The APIs will return a Hash with "error".

If you rescue CoinbaseCommerce::CoinbaseCommerceError, you are provided with the error message itself as well as a code attribute that you can map onto the API's error list. The API docs list possible errors at the bottom of each page. Here's how you might do that:

begin
  coinbase_commerce.checkouts.all
rescue CoinbaseCommerce::CoinbaseCommerceError => e
  # do something with e.message here
  # do something wiht e.code here
end
