balanced-erlang: balancedpayments client. erlang flavored.

Status

balanced-erlang is a minimal balancedpayments client.

It currently only supports operations required to pay and get paid. Anything else you need can be handled from the balancedpayments console for now.

The operations we have so far: creating a new anonymous account, creating a new account as a person/merchant so they can receive payments, attaching a credit card to an account, attaching a bank account to an account, debiting a credit card, and crediting a bank account.

Usage

Note: The last few errors above are normal. The balanced dev tokens/keys/URIs don't work properly for actual testing. Annoying.

Configuration

You must start inets and ssl before using balanced.

By default, erlang-balanced uses the global balanced API test token. You must change this to your private API key before you can receive payments:

inets:start(),
ssl:start(),
application:start(balanced),
application:set_env(balanced, auth_token, "da3da6de7c9311e288c9026ba7f8ec28").

Building

    rebar get-deps
    rebar compile

Testing

    rebar eunit skip_deps=true suite=balanced

Next Steps

In no specific order:

  • Flesh out remaining balanced API
  • Add tests for error conditions
  • Move from env-specified auth token to something more call specific
    • Options:
      • Per-call auth token (balanced:charge_card(AuthToken, ...))
      • Leave env, but add per-auth token options
