Ruby::Daraja is a Ruby wrapper for the Safaricom Daraja API. It provides a simple interface to the API endpoints and allows for smooth setup in Ruby on Rails applications or any other Ruby application.

IMPORTANT: This gem is not yet released to rubygems.org. The instructions below are for when the gem is released.

Install the gem and add to the application's Gemfile by executing:

$ bundle add ruby-daraja

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install ruby-daraja

With ruby-daraja you can easily make requests to the Safaricom Daraja API. The DSL is simple and easy to use. The DSL is divided into two parts:

1. Configuration
2. Requests
   1. Register C2B URLs
   2. MPESA PayBill
   3. MPESA Buy Goods And Services

In order to get started with the DSL, you need to configure the gem with your credentials.

There are two ways to get started with ruby-daraja:

1. Development
2. Production

This is a quick-start mode for the gem. It is meant to get you up and running quickly. It is not recommended for production applications. To get started with the gem in development mode, follow the steps below:

1. Setup environment variables needed for your application. The environment variables needed are:

   # mandatory variables
   CONSUMER_KEY='daraja consumer key here'
   CONSUMER_SECRET='daraja consumer secret here'
   
   # optional variables
   VALIDATION_URL='C2B Validation URL'
   CONFIRMATION_URL='C2B Confirmation URL'
   IS_SANDBOX='boolean indicating whether you are in sandbox or production'
   SHORT_CODE='daraja (paybill /till number) short code here'
   B2C_RESULT_URL='B2C Result URL'
   INITIATOR_NAME='B2C initiator name'
   INITIATOR_PASSWORD='B2C initiator password'
   SSL_CERTIFICATE='path to SSL certificate'
   BALANCE_RESULT_URL='Balance Result URL' 

2. You will need a Daraja::AppConfig instance. This instance is used to configure the application. It is created as follows:

   require 'ruby-daraja'
   
   app_config = Daraja::Default.new._app_config

TODO: Add instructions for production mode

1. Register C2B URLs - This needs to be done only once for each set of URLs.

   require 'ruby-daraja'
   
   app_config = `Daraja::AppConfig instance here`
   responses =  app_config.register_urls # array of JSON responses from Safaricom Daraja API

1. Create a new Daraja::PayBill instance.

   require 'ruby-daraja'
   
   app_config = `Daraja::AppConfig instance here`
   paybill_client = Daraja::PayBill.new(config: app_config, pass_key: 'pass key here')

2. Initiate Payment Request (STK Push) for MPESA PayBill.

    response = paybill_client.initiate_stk_push(
      amount: 1,
      phone_number: '2547xxxxxxxx',
      account_reference: 'account reference',
      transaction_description: 'transaction description'
    ) # JSON response from Safaricom Daraja API

3. Initiate B2C Request for MPESA PayBill

   response = paybill_client.initiate_b2c(
     amount: 1,
     phone_number: '2547xxxxxxxx',
     type: 0, # 0 for business, 1 for salary, 2 for promotion
     remarks: 'remarks',
     occasion: 'occasion'
   ) # JSON response from Safaricom Daraja API

4. Check balance for MPESA PayBill

   response = paybill_client.initiate_balance_request(
        remarks: 'remarks'
   ) # JSON response from Safaricom Daraja API

1. Create a new Daraja::BuyGoods instance.

   require 'ruby-daraja'
   
   app_config = `Daraja::AppConfig instance here`
   till_client = Daraja::BuyGoods.new(config: app_config, pass_key: 'pass key here')

2. Initiate Payment Request (STK Push) for MPESA Buy Goods And Services.

    response = till_client.initiate_stk_push(
      amount: 1,
      phone_number: '2547xxxxxxxx',
      account_reference: 'account reference',
      transaction_description: 'transaction description'
    ) # JSON response from Safaricom Daraja API

3. Initiate B2C Request for MPESA Buy Goods And Services

   response = till_client.initiate_b2c(
     amount: 1,
     phone_number: '2547xxxxxxxx',
     type: 0, # 0 for business, 1 for salary, 2 for promotion
     remarks: 'remarks',
     occasion: 'occasion'
   ) # JSON response from Safaricom Daraja API

4. Check balance for MPESA Buy Goods And Services

   response = till_client.initiate_balance_request(
        remarks: 'remarks'
   ) # JSON response from Safaricom Daraja API

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