Flutterwave

Ruby SDK for convenient access to the Flutterwave API from Ruby applications. Full API documentation avaialable at https://www.flutterwave.com/documentation

gem install flutterwave

By default, the base API URL used is the test/staging URL - http://staging1flutterwave.co:8080

To change to production, set the value of the FLUTTERWAVE_BASE_URL environment variable to https://prod1flutterwave.co:8181

Here's a guide on cross-platform ways to set environment variables - https://www.twilio.com/blog/2015/02/managing-development-environment-variables-across-multiple-ruby-applications.html

The library needs to be configured with your merchant key and API key. These are accessible from the Settings panel at https://www.flutterwavedev.com/

To initialize the Ruby client:

require 'flutterwave'

merchant_key = 'tk_aT0BPO14Rs'
api_key = 'tk_ybh0luGWQbM04Is15lXh'
client = Flutterwave::Client.new(merchant_key, api_key)

All API operations are performed through the client instance. API responses are used to initialize a response class that allows direct access to JSON keys as methods. Arguments to operation methods adapt the same signature as sample requests to the API endpoint.

For instance, an API call that returns:

{
  "data": {
    "responsecode": "02",
    "responsemessage": "Successful, pending OTP validation",
    "transactionreference": "ABC1234444"
  },
  "status": "success"
}

Gets initialized as a Flutterwave::Response object with method keys - responsecode, responsemessage, transactionreference, successful?, failed?

An example using the wrapper for accessing https://www.flutterwave.com/documentation/alternative-payments/

The resend-otp operation could be accessed through this sample:

client = Flutterwave::Client.new('sample_merchant_key', 'sample_api_key')
response = client.account.resend({
  validateoption: 'SMS',
  transactionreference: 'FLW02391188'
})

print response.responsemessage if response.successful?

The method arguments to the resend method match the same hash-signature as the request sample at https://www.flutterwave.com/documentation/alternative-payments/#resend-otp.

Response from the API is used to construct an instance of Flutterwave::Response which makes keys in the data hash accessible as methods.

The only operation that does not follow the description above is when obtaining listing of banks, alongside their codes and names. To ease operation with the listing, a Flutterwave::Bank object is created for each bank object returned by the API. The Flutterwave::BankAPI also comes with some helper methods that help find a bank by code, or by a regex matching the bank's name.

An example usage is described below:

client = Flutterwave::Client.new('sample_merchant_key', 'sample_api_key')
all_banks = client.bank.list
names_of_all_banks = all_banks.inject([]) { |list, bank| list << bank.name }

p names_of_all_banks # => ["Fidelity Bank", "Heritage"..."Unity Bank"]

# sample for finding a bank by name
access_bank_code = client.bank.find_by_name('access').code # => '044'

# sample for finding a bank by code
bank_name = client.bank.find_by_code('058').name # => GTBank Plc

Each method has the corresponding API link as a comment above the method signature. To access details about the arguments to the method, please see the tests for that class, or visit the API link.
