Before you make a payment please check if your SDK is initialized

Include a model

Add model inclusion to your source code:

require 'judopay/models/card_preauth'
Create pre-authorization

To make a new pre-authorization with full card details:

preauth = Judopay::CardPreauth.new(
  :your_consumer_reference => 'xxxxxxxx',
  :your_payment_reference => 'xxxxxxxx',
  :amount => 5.01,
  :card_number => '4976000000003436',
  :expiry_date => '12/20',
  :cv2 => '452',
  :currency => 'GBP',
  :card_address => {
    :line1 => '32 Edward Street',
    :town => 'Camborne',
    :postcode => 'TR14 8PA'
  },
  :consumer_location => {
    :latitude => 51.5033630,
    :longitude => -0.1276250
  }
)

Note: Please make sure that you are using a unique Consumer Reference for each different consumer, and a unique Payment Reference for each transaction.

You can check on the required fields and the format of each field in the Judopay REST API reference.

Check the pre-authorization result

And after that you need to send the request to the API. Your code will look like that:

    result_preauth = preauth.create
    
    if result_preauth.result == 'Success'
        puts 'Preauth successful'
    else
        puts 'There were some problems while processing your preauth'
    end

If the pre-authorization is successful, you'll receive a response array like this:

{
  "receipt_id"=>"xxxxxxxxxxx",
  "your_payment_reference"=>"xxxxxxxx",
  "type"=>"PreAuth",
  "created_at"=>"2016-09-23T09:34:43.2486+01:00",
  "result"=>"Success",
  "message"=>"xxxxxxxxxxx",
  "judo_id"=>"xxxxxxxxxxx",
  "merchant_name"=>"xxxxxxxxxxx",
  "appears_on_statement_as"=>"xxxxxxxxxxx",
  "original_amount"=>"5.01",
  "amount_collected"=>"0.00",
  "net_amount"=>"5.01",
  "amount"=>"5.01",
  "currency"=>"GBP",
  "card_details"=>{
    "card_lastfour"=>"3436",
    "end_date"=>"1220",
    "card_token"=>"xxxxxxxxxxx",
    "card_type"=>1
  },
  "consumer"=>{
    "consumer_token"=>"xxxxxxxxxxx",
    "your_consumer_reference"=>"xxxxxxxx"
  },
  "risks"=>{
    "post_code_check"=>"PASSED"
  }
}

It is also important to handle different exceptions in your code. See our Error handling section.
