rails payments through payumoney

Question

I am trying to integrate payumoney payment gateway to my rails application.

I added the gem active_merchant_payu_in ,but after this am unable to start the app..and getting this console error "warning: already initialized constant APP_PATH ".. I found that this module is from activemerchant so I installed that in my gemfile instead of this and now my app starts.

As per docs this is how we setup activemerchant

ActiveMerchant::Billing::Base.mode = :test
      ::SAMPLEGATEWAY = ActiveMerchant::Billing::TrustCommerceGateway.new(
          :login => 'TestMerchant',
          :password => 'password')

So for payu I changed the gateway as below, but what should i pass instead of :login and :password in below code?

 ActiveMerchant::Billing::Base.mode = :test
  ::GATEWAY = ActiveMerchant::Billing::PayuInGateway.new(
      )

For payumoney what we all have is

Merchant ID, Merchant Key, Merchant Salt

I can't find enough documentation on it anywhere..Could someone shed some light into this topic??

Answer 1

It's easy to integrate PayU with following gem, https://github.com/payu-india/PayU-Integration-Kit-ROR

Integration process is like 3 steps

1) Configure button on view (with credentials and params), on button select it takes to payu page.

2) Payu document has test credentials to test in payu page.

3)Writing a route to get response from the payu and receive the transaction status.

Gem is taken care by checksum checks, helpers, getting cart id, etc.
