Simply Beautiful Elixir library for the Plaid API.

motivation-principles

Motivation & Principles

1. Provide FANTASTIC documentation
2. Full plaid API coverage
3. Use the plaid API versioning plan
4. Return well-defined structs, always

Example Usage

# get auth data
Plaid.Auth.get("access-prod-123xxx", client_id: "123", secret: "abc")

# get item details
Plaid.Item.get("access-prod-123xxx", client_id: "123", secret: "abc", env: :production)

# refresh transactions
Plaid.Transactions.refresh("access-prod-123xxx", client_id: "123", secret: "abc", env: :development)

configuration

Configuration

Each function takes a Plaid.config keyword list as it's trailing argument. Authenticated requests require a client_id and secert at minimum for authentication with the plaid API.

Key	Value
:client_id	Your plaid client id. (required for authenticated requests)
:secret	Your plaid secret. (required for authenticated requests)
:env	Either :production, :development, or :sandbox. (defaults to :sandbox)
:http_client	Any module that implements the Plaid.Client behaviour. (defaults to Plaid.Client.HTTPoison)
:test_api_host	Any base URL e.g. http://localhost:2100/.

The choice to avoid using application configuration is due to the anti-pattern documented by elixir of libraries using application configuration. Passing configuration to each function avoids the library touching any global state, as well as making function calls objectively more "functional".

Likely you will need to pass keys dynamically anyway for development/production, overwriting the need for global application config. Therefore using patterns like those outlined in this blog post and using a test mocking library like Mox help aid in making code more clear.

installation

Installation

    # optional, but recommended http client
    {:httpoison, "~> 1.7"}
  ]
end
