Centralpos Build Status

Installation

Add this line to your application's Gemfile:

gem 'centralpos'

And then execute:

$ bundle

Or install it yourself as:

$ gem install centralpos

Setup

You should first configure the WSDL endpoints (Sandbox & Production), by doing:

Centralpos.setup do |config|
  config.sandbox_wsdl_endpoint = 'https://sandbox.example.com?wsdl'
  config.production_wsdl_endpoint = 'https://production.example.com?wsdl'
end

In a Rails environment make sense to place this in an initializer.

Usage

In order to use this gem you must already have an account in Centralpos. Once you have it you can do the following:

  • Initialize and Account
  • Ask about Batches
  • Do stuff with an open Batch - Transactions

Initialize an Account

Load the Account with the "username" and "password", in order to ask for the batches and everything:

account = Centralpos::Account.new("username", "password")

now that you have the account you can ensure that the credentials are valid calling,

account.valid?

or ask for the cards that you are able to process with Centralpos,

account.enabled_cards

Ask about Batches

With an account loaded and valid? you can now ask about the open batches that this account has at the moment. Remember that this batches are the only one that accept new transactions to be process later on,

open_batches = account.open_batches # returns an Array of Centralpos::Batch instances

Or if you already have the batch ID you can ask directly about it,

batch = account.batch(id) # returns a Centralpos::Batch instance

If you want to know all the past batches, that are not open, you can ask them by,

past_batches = account.past_batches # returns an Array of Centralpos::Batch instances

Do stuff with an open Batch - Transactions

With an open_batch loaded we can start adding, removing or updating transactions to it, in order to process them afterwards. And also check the transactions that are already present in it

Let's create a transaction first, for this we have to pass the parameters as arguments to initialize it:

transaction_params = {
    owner_id: "owner_id1",
    cc_number: "4111111111111111",
    amount: 100.0,
}
transaction = Centralpos::Transaction.new(transaction_params)

IMPORTANT: The value of :owner_id can only appear once in a batch and this value it is the one that is being use to remove a transaction from an open batch.

There are also to optional values that you can pass to the transaction, this are:

transaction_params = transaction_params.merge({
    optional_data_1: "",
    optional_data_2: ""
})

So now with a valid transaction (yes you can call to transaction.valid? or transaction.invalid?) you can add it to the open batch,

open_batch.add_transaction(transaction)

and maybe because you make a mistake you want to remove a transaction of a open batch, to do it you have to remember that the value that it's used to match the transaction that you want to remove is the owner_id in the transaction instance, so

open_batch.remove_transaction(transaction)

You can also be able to update a transaction that it's already in the open batch, and as you can imagine you only can update the cc_number, amount, optional_data_1 and optional_data_2 values of the transaction, so

transaction.amount = 250.0
open_batch.update_transaction(transaction)

on the back what this is doing is removing the transaction from the open batch and adding it again with the new values, that's why you can't change the owner_id value of it.

TO-DOs:

  • Add tests
  • Add missing methods

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
