Coinbase.Pro.REST (coinbasepro_rest v1.0.0) View Source

This package implements a low-level REST API of the Coinbase Pro. Low-level means it is just a wrapper over HTTP library which handles authentication, request signing and has a few nice helper functions but you still have to construct URLs and interpret responses on your own.

If you want to use a high-level API, see elixir-coinbase/coinbasepro.

Installation

If available in Hex, the package can be installed by adding coinbasepro_rest to your list of dependencies in mix.exs:

def deps do
  [
    {:coinbasepro_rest, "~> 1.0"}
  ]
end

Additional dependencies

As it uses Tesla underneath, you have to follow its installation instructions. Specifically, you have to install JSON library and you probably should install a HTTP client library as default HTTP client based on httpc does not validate SSL certificates.

For example, add Jason and Hackney to the dependencies in mix.exs:

defp deps do
  [
    {:hackney, "~> 1.16.0"},
    {:jason, ">= 1.0.0"}
  ]
end

Configure default adapter in config/config.exs (optional).

config :tesla, adapter: Tesla.Adapter.Hackney

See Tesla's README for list of supported HTTP and JSON libraries.

Configuration

Base URL

By default, the API sends requests to the production API. If you want to use Sandbox, you can add the following to the config/config.exs:

config :coinbasepro_rest, :base_url, "https://api-public.sandbox.pro.coinbase.com"

User Agent

It is a good idea to override the default value of the User-Agent header added to the requests to something that clearly identifies your application name and version. If you want to do this, you can add the following to the config/config.exs:

config :coinbasepro_rest, :user_agent, "MyApp/1.0.0"

Usage

In order to issue GET request

alias Coinbase.Pro.REST.{Context,Request}
# Obtain these values from Coinbase
context = %Context{key: "...", secret: "...", passphrase: "..."}

{:ok, response} = Request.get(context, "/orders?limit=10")
{:ok, response} = Request.post(context, "/deposits/payment-method", %{
  "amount": 10.00,
  "currency": "USD",
  "payment_method_id": "bc677162-d934-5f1a-968c-a496b1c1270b"
})
