Integrate instamojo api in rails app - ruby-on-rails

Question

I am learning payment gateway integration in rails.
I chose insta mojo and was working but the documentation they provide is very inconvenient and hard to understand..
https://github.com/AnkurGel/Instamojo-rb#usage
I have no idea where to Set my API keys
require 'Instamojo-rb'
api = Instamojo::API.new do |app|
app.api_key = "api_key-you-received-from-api#instamojo.com"
app.auth_token = "auth_token-you-received-from-api#instamojo.com"
end`
I tried instamojo.rb in initializers and tries to run console but it gives error that no such method exists.

Answer 1

You can put require statement in application.rb or anywhere else so that file is loaded while application is loading.
You can make 'Payment' model in which you can make methods like verify and get details.
Internally in those methods, you will be making API object and using the above code.
class Payment < ActiveRecord::Base
def verify
client = get_intamojo_client
#Some code
end
def get_details
client = get_intamojo_client
#Some code
end
private
def get_instamojo_client
api = Instamojo::API.new(ENV["INSTAMOJO_KEY"],{auth_token: ENV["INSTAMOJO_TOKEN"], endpoint:"https://test.instamojo.com/api/1.1/"})
return api.client
end
end
And to explore what you can do using client object, just use rails console and make a client object there, and use client.public_methods and start exploring.
EDIT:
I think you are using older version of gem i.e 0.1, their documentation is for version > 1.0. To update, use this gem 'Instamojo-rb', '~> 1.1' in gem file and use bundle update.
So for version 0.1, use
api = Instamojo::API.new(ENV["INSTAMOJO_KEY"],{auth_token: ENV["INSTAMOJO_TOKEN"], endpoint:"https://test.instamojo.com/api/1.1/"})
And for versino >= 1.0, use
api = Instamojo::API.new(ENV["INSTAMOJO_KEY"], ENV["INSTAMOJO_TOKEN"], "https://test.instamojo.com/api/1.1/")
