# Fawry

[README - متوفر باللغة العربية](https://github.com/fawry-api/fawry/blob/master/README-ar.md)

**Disclaimer:** we are _not officially affilated_ with the _Fawry_ company.

A plug-and-play library that makes interfacing with Fawry's payment gateway API a breeze:

_Fawry's production and sandbox environments are supported._

_This library is tested on Ruby v2.6, 2.7, 3.0_

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'fawry'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install fawry
    
## Configuration

Add an initializer `fawry.rb` in your application to configure the library:
```ruby
Fawry.configure do |config|
  config.sandbox = Rails.env.staging? ? true : false
  config.fawry_secure_key = 'fawry_secure_key'
  config.fawry_merchant_code = 'fawry_merchant_code'
end
```
Alternatively, you could use the environment variables: `FAWRY_SANDBOX`, `FAWRY_SECURE_KEY`, and `FAWRY_MERCHANT_CODE`.

## Usage

## TODO:

- Add option to raise exception on request failure

## Development

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.

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](https://rubygems.org).
