Installation
Add this line to your application's Gemfile:
gem 'qiwi-pay'
And then execute:
$ bundle
Or install it yourself as:
$ gem install qiwi-pay
Usage
There are three types of interactions with QiwiPay service:
- Performing Web Payment Form requests
- Performing JSON API requests
- Handling callback confirmation requests
Prepare credentials object
To perform any request you must provide your QiwiPay credentials. For doing that the Credentials
object should be used.
# Create credentials object
# You can use PKCS#12 container
p12 = OpenSSL::PKCS12.new(File.read('qiwi.p12'))
crds = QiwiPay::Credentials.new secret: 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA',
p12: p12
# ... or provide certificate and key objects explicitly
crds = QiwiPay::Credentials.new secret: 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA',
cert: p12.certificate,
key: p12.key
# ... or load from separate files
crds = QiwiPay::Credentials.new secret: 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA',
cert: 'my.crt',
key: 'my.key'
Create cheque object
See Cheque section of Official QiwiPay documentation for details.
cheque = QiwiPay::Cheque.new seller_id: 12345678901,
cheque_type: QiwiPay::Cheque::Type::INFLOW,
customer_contact: 'client@example.com',
tax_system: QiwiPay::Cheque::TaxMode::USN_DR,
positions: [{
quantity: 1,
price: 10_000,
tax: QiwiPay::Cheque::VAT::NONE,
description: 'Order #1234 payment'
}]
Perform payment operations using WPF
Only two types of payment operations are available for now:
- sale - single-step payment operation
- auth - initiate multi-steps payment operation
Operations are used in very similar way. Use QiwiPay::Wpf::SaleOperation
class for sale operation and QiwiPay::Wpf::AuthOperation
class for auth operation.
See WPF section of Official QiwiPay documentation for details.
Create payment operation object
op = QiwiPay::Wpf::SaleOperation.new crds,
merchant_site: 111_111,
currency: 643,
email: 'client@example.com',
country: 'RUS',
city: 'Moscow',
amount: 10_000,
order_id: 1234,
product_name: 'Flowers',
merchant_uid: 432101,
order_expire: Time.now + 3600,
callback_url: 'https://example.com/payment/callback'
op.cheque = cheque
Build redirection URL for sale operation form
op.url
=> 'https://pay.qiwi.com/paypage/initial?opcode=1&merchant_site=111111¤cy=643&amount=1000.00&order_id=1234&email=client@example.com&country=RUS&city=Moscow&product_name=%D0%9E%D0%BF%D0%BB%D0%B0%D1%82%D0%B0+%D1%82%D1%83%D1%80%D0%B0&merchant_uid=432101&callback_url=https%3A%2F%example.com%2Fpayment%2Fcallback&sign=...c4dbf...'
Build form params WPF sale operation
This may be useful if you would like to construct redirection URL or invisible payment form by yourself.
op.params
=> {:method=>:get,
:url=>"https://pay.qiwi.com/paypage/initial",
:opcode=>"1",
:merchant_site=>"111111",
:currency=>"643",
:amount=>"1000.00",
:order_id=>"1234",
:email=>"client@example.com",
:country=>"RUS",
:city=>"Moscow",
:product_name=>"Flowers",
:merchant_uid=>"432101",
:callback_url=>"https://example.com/payment/callback",
:sign=>"...c4dbf..."}
Process QiwiPay confirmation callback
After payment operation has been finished you will receive a confirmation callback request from Qiwi service. Use the request's (ActionDispatch::Request
, Rack::Request
or whatever it is) parameters hash to build QiwiPay::Confirmation
object.
conf = QiwiPay::Confirmation.new crds, request.params
Now you have a seamless way to access confirmation data and perform some tests on it.
# Check if ip address is a valid Qiwi server address
conf.valid_server_ip? request.ip
=> true
# Check signature
conf.valid_sign?
=> true
# Read confirmation data
conf.txn_id
=> 11728960050
conf.order_id
=> 1234
conf.error_code
=> 0
conf.error_message
=> "No error"
conf.error?
=> false
conf.txn_status_message
=> "Authorized"
conf.txn_type_message
=> "Purchase: auth"
# Check if transaction was successful (valid signature and no error)
conf.success?
=> true
# Get all confirmation data as a hash
conf.to_h
=> {:txn_id=>11728960050,
:txn_status=>2,
:txn_type=>1,
:txn_date=>"2018-05-03T15:55:18+00:00",
:error_code=>0,
:pan=>"510000******0082",
:amount=>"10000.00",
:currency=>643,
:auth_code=>nil,
:eci=>nil,
:card_name=>nil,
:card_bank=>nil,

:card_token_expire=>nil,
:sign=>"27A56431CD3A14BA34...8A",
:txn_status_message=>"Authorized",
:txn_type_message=>"Single-step purchase"}
Perform payment operations using JSON API
Following operations are available for now:
-
capture -
QiwiPay::Api::CaptureOperation
class -
refund -
QiwiPay::Api::RefundOperation
class -
reversal -
QiwiPay::Api::ReversalOperation
class -
status -
QiwiPay::Api::StatusOperation
class
Status operation
Create and perform status
operation object
op = QiwiPay::Api::StatusOperation.new crds,
merchant_site: 111111,
txn_id: 11728960050,
order_id: 1234
response = op.perform
Operations' perform
methods return QiwiPay::Api::Response
object. It allow you to get text messages for errors, codes and statuses. See Transaction statuses section of Official QiwiPay documentation
In case the JSON API response parsing fails, the whole response body is returned by Response
's error_message
method and the error_code
is set to -1.
Operation succeeded
response.success?
=> true
response.error_code
=> 0
response.error_message
=> "No errors"
Operation failed
response.success?
=> false
response.http_code
=> 200
response.error_code
=> 8021
response.error_message
=> "Merchant site not found"
Refund/reversal operation
Both operations are performed in the same way, just use the right class.
op = QiwiPay::Api::RefundOperation.new crds,
merchant_site: 111111,
txn_id: 11728960050,
amount: 500,
cheque: cheque
response = op.perform
=> #<QiwiPay::Api::Response http_code=200 error_code=8018 ...>
response.success?
=> false
response.http_code
=> 200
response.error_code
=> 8018
response.error_message
=> "Parsing error"
response.to_h
=> {:request_id => "01234567-89ab-cdef-0123-456789abcdef",
:error_message => "Parsing error",
:error_code => 8018,
:http_code => 200
}
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
or rake console
or rake c
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
