1.2.1. Sale Transactions

Direct integration

General Sale Process Flow

Merchant initiates a transaction by sending HTTPS POST request to the specified URL
PaynetEasy server immediately returns the response back to Merchant. The response contains paynet-order-id. For detailed request and response format see Sale Request Parameters Table
Merchant shows the Customer message like Your order is being processed. Please, wait…. Merchant starts polling PaynetEasy server for transaction status using paynet-order-id obtained at previous step. Status polling request and response are described in Order status asynchronous call
PaynetEasy Server determines if 3D is required or not and drives the transaction authorization process as appropriate.
Merchant is using single entry point for both 3D and Non 3D Sale transactions. Actually the Merchant can not know beforehand if the sale will be driven through 3D authorization scheme. The Merchant should use PaynetEasy API as described below.

checkout order Customer checks out the order on Merchant’s website
process sale Merchant sends Sale request to PaynetEasy server with specified parameters described in Sale Request Parameters. Merchant must make sure redirect_url is passed. This is the URL the Customer will be redirected after 3D transaction is processed. redirect_url is not used if the transaction goes through Non 3D process.
order status=processing PaynetEasy Server immediately returns response with order status processing. See details at Sale Response
Get Order status Merchant starts polling PaynetEasy server for transaction status using paynet-order-id obtained at previous step. Status polling request and response are described in Order status asynchronous call.
3D status required? PaynetEasy Gateway determines if 3D authorization required for the incoming sale transaction.
non 3D sale process In case the gate is Non 3D PaynetEasy returns empty html parameter and Merchant should keep polling PaynetEasy server until approved or declined status is returned. See Non 3D Sale transaction diagram for details.
3D sale process In case the gate is 3D PaynetEasy returns non-empty html parameter Merchant should follow 3D sale process starting from step 5 described in 3D Sale transaction diagram.

Non 3D Sale transaction diagram

Merchant is using single entry point for both 3D and Non 3D Sale transactions. Actually the Merchant can not know beforehand if the Sale will be driven through 3D authorization scheme. The Merchant should use PaynetEasy API as described in General Sale Process Flow.

Return 3D response with auth form PaynetEasy server returns response including auth form HTML to Merchant. See details at Sale Response
Show 3D form to customer Merchant shows Customer Issuer Bank’s extra authentication form
Customer submits additional auth information Customer follows Issuer Bank’s process to provide additional authorization information. The most usual way it’s accomplished is sending SMS message with a secret code to customer’s mobile phone which number is known to Issuer Bank. Customer then supplies this secret code through the auth form.
Authorized The Issuer Bank verifies that extra authorization information supplied by the Customer is correct and replies back to PaynetEasy server.
Process Sale PaynetEasy server forwards Sale request to bank acquirer. The bank starts processing the transaction.
Sale result The bank responds to PaynetEasy server with approve or decline for requested Sale
Show auto-submit order form PaynetEasy server creates order and redirects customer’s browser to auto-submit form with supplied order id. The form’s action is redirect_url passed at step 2.
Auto-submit form with order id and status Customer’s browser automatically submits the form with order id and status to Merchant’s redirect_url passed at step 2. Status may be either approved or declined

3D redirect

If your gate supports 3D Secure you need to send status request and process html return parameter to send customer to 3D Secure Authorisation. The simplified schema looks like:

Customer -> Merchant: Initiate transaction
activate Merchant

Merchant -> "PaynetEasy": sale
activate "PaynetEasy"
"PaynetEasy" --> Merchant: async-response
Merchant -> "PaynetEasy": status
"PaynetEasy" --> Merchant: html
deactivate "PaynetEasy"
Merchant --> Customer: urldecode(html)
deactivate Merchant

html field is always present for 3D gates in status response, whether clients card supports 3D Secure or not.

Upon completion of 3D authorization process by the Customer he/she is automatically redirected to redirect_url. The redirection is performed as an HTTPS POST request with the parameters specified in the following table.

3D redirect Parameter Description
status See Status List for details.
orderid Order id assigned to the order by PaynetEasy
merchant_order Merchant order id
client_orderid Merchant order id
error_message If status is declined or error this parameter contains the reason for decline or error details
control Checksum used to ensure that it is PaynetEasy (and not a fraudster) that initiates the request. This is SHA-1 checksum of the concatenation status + orderid + client_orderid + merchant-control.
descriptor Gate descriptor

If Merchant has passed server_callback_url in original Sale request PaynetEasy will call this URL. Merchant may use it for custom processing of the transaction completion, e.g. to collect sales data in Merchant’s database. The parameters sent to this URL are specified in Sale, Return Callback Parameters

Server callback result

Upon completion by the System of 3D request processing it returns the result on the specified server_callback_url with the parameters described in Merchant Callbacks

The checksum is used to ensure that the callback is initiated for a particular Merchant, and not for anybody else claiming to be such Merchant. This SHA-1 checksum, the control parameter, is created by concatenation of the parameters values in the following order:

  • status
  • orderid
  • client_orderid
  • merchant_control

A complete string example may look as follows:

approvedS279G323P4T1209294c258d6536ababe653E8E45B5-7682-42D8-6ECC-FB794F6B11B1

Encrypt the string using SHA-1 algorithm. The resultant string yields the control parameter. For the above-mentioned example the control will take the following value:

e04bd50531f45f9fc76917ac78a82f3efaf0049c

All parameters are sent via GET method.

For more information, see Merchant Callbacks

Server callback result example

status=declined
&error-message=Decline, refer to card issuer
&error-code=107
&paynet-order-id=S279G323P4T1209294
&merchant-order-id=c258d6536ababe65

Sale request authorization through control parameter

The checksum is used to ensure that it is a particular Merchant (and not a fraudster) that initiates the transaction. This SHA-1 checksum, the parameter control, is created by concatenation of the parameters’ values in the following order:

  • ENDPOINTID/ENDPOINTGROUPID
  • client_orderid
  • minimal monetary units amount (i.e. cent, penny etc.)
  • email
  • merchant_control

A complete string example may look as follows:

59I6email@client.com3E8E45B5-2-42D8-6ECC-FBF6B11B1

Encrypt the string using SHA-1 algorithm. The resultant string yields the control parameter (see Sale Request Parameters) which is required for request authorization. For the above-mentioned example the control will take the following value:

d02e67236575a8e02dea5e094f3c8f12f0db43d7

Order status

Merchant must use Order status API call to get the customer’s order transaction status. After any type of transaction is sent to PaynetEasy server and order id is returned, Merchant should poll for transaction status. When transaction is processed on PaynetEasy server side it returns it’s status back to Merchant and at this moment the Merchant is ready to show the customer transaction result, whether it’s approved or declined.

Status API URL

For integration purposes use staging environment sandbox.payneteasy.com instead of production gate.payneteasy.com. Status API calls are initiated through HTTPS POST request by using URL in the following format:

The End point ID is an entry point for incoming Merchant’s transactions for single currency integration. https://gate.payneteasy.com/paynet/api/v2/status/ENDPOINTID

The End point group ID is an entry point for incoming Merchant’s transactions for multi currency integration. https://gate.payneteasy.com/paynet/api/v2/status/group/ENDPOINTGROUPID

Order status call parameters

Status call parameters Description
login Merchant login name
client_orderid Merchant order identifier of the transaction for which the status is requested
orderid Order id assigned to the order by PaynetEasy
by-request-sn Serial number assigned to the specific request by PaynetEasy. If this field exist in status request, status response return for this specific request.
control Checksum used to ensure that it is PaynetEasy (and not a fraudster) that initiates the callback for a particular Merchant. This is SHA-1 checksum of the concatenation login + client-order-id + paynet-order-id + merchant-control. See Order status API call authorization through control parameter for more details about generating control checksum.

Order Status Response

Status Response Parameter Description
type The type of response. May be status-response
status See Status List for details.

html HTML code of 3D authorization form, encoded in application/x-www-form-urlencoded MIME format. Merchant must decode this parameter before showing the form to the Customer. The PaynetEasy System returns the following response parameters when it gets 3D authorization form from the Issuer Bank. It contains auth form HTML code which must be passed through without any changes to the client’s browser. This parameter exists and has value only when the redirection HTML is already available. For non-3D this never happens. For 3D HTML has value after some short time after the processing has been started.
serial-number Unique number assigned by PaynetEasy server to particular request from the Merchant.

Status request authorization through control parameter

The checksum is used to ensure that it is Merchant (and not a fraudster) that sends the request to PaynetEasy. This SHA-1 checksum, the parameter control, is created by concatenation of these parameters values in the following order:

  • login
  • client_orderid
  • orderid
  • merchant_control

For example, assume these parameters have the values as listed below:

Parameter Name Parameter Value
login cool_merchant
client_orderid 5624444333322221111110
orderid 9625
merchant_control r45a019070772d1c4c2b503bbdc0fa22

The complete string example may look as follows:

cool_merchant56244443333222211111109625r45a019070772d1c4c2b503bbdc0fa22

Encrypt the string using SHA-1 algorithm. The resultant string yields the control parameter which is required for authorizing the callback. For the example control above will take the following value:

c52cfb609f20a3677eb280cc4709278ea8f7024c

Payment Form Integration

Payment Form integration is relevant for merchants who are not able to accept customer card details (merchant’s website must complete PCI DSS certification). In case of Payment Form integration merchant is released of accepting payment details and all this stuff is completely implemented on the PaynetEasy gateway side. In addition merchant may customize the look and feel of the Payment Form. Merchant must send the template to his/her Manager for approval before it could be used.

Payment Form API URL

For integration purposes use staging environment sandbox.payneteasy.com instead of production gate.payneteasy.com. Payment Form transactions are initiated through HTTPS POST request by using URL in the following format:

Form Transaction by ENDPOINTID

The End point ID is an entry point for incoming Merchant’s transactions for single currency integration.

https://gate.payneteasy.com/paynet/api/v2/sale-form/ENDPOINTID - for sale transactions
https://gate.payneteasy.com/paynet/api/v2/preauth-form/ENDPOINTID - for preauth transactions
https://gate.payneteasy.com/paynet/api/v2/transfer-form/ENDPOINTID - for transfer transactions

Form Transaction by ENDPOINTGROUPID

The End point group ID is an entry point for incoming Merchant’s transactions for multi currency integration.

https://gate.payneteasy.com/paynet/api/v2/sale-form/group/ENDPOINTGROUPID - for sale transactions
https://gate.payneteasy.com/paynet/api/v2/preauth-form/group/ENDPOINTGROUPID - for preauth transactions
https://gate.payneteasy.com/paynet/api/v2/transfer-form/group/ENDPOINTGROUPID - for transfer transactions

General Payment Form Process Flow

    Customer -> Merchant: Checkout
activate Merchant

alt sale
Merchant -> "PaynetEasy": sale-form/ENDPOINTID
activate "PaynetEasy"
else preauth
    Merchant -> "PaynetEasy": preauth-form/ENDPOINTID
else transfer
    Merchant -> "PaynetEasy": transfer-form/ENDPOINTID
end

"PaynetEasy" --> Merchant: status=processing
deactivate "PaynetEasy"
deactivate Merchant

Customer -> Customer: Input cardholder data
Customer -> "PaynetEasy": Submit form
activate "PaynetEasy"
"PaynetEasy" -> "PaynetEasy": Processing
"PaynetEasy" --> Customer: Redirect to **redirect_url**
deactivate "PaynetEasy"

Customer -> Merchant: Return to the Shop

alt status
  loop
     Merchant -> "PaynetEasy": status/ENDPOINTID
     activate "PaynetEasy"
     "PaynetEasy" --> Merchant: status=processing
     deactivate "PaynetEasy"
    end
  else callback
   ... transaction processing ...
   "PaynetEasy" --> Merchant: Callback notification
end

Checkout – Customer proceeds to order checkout
Merchant initiates a transaction by sending HTTPS POST request to the specified URL. It should be either /sale-form/ENDPOINTID or /preauth-form/ENDPOINTID depending which transaction SMS or DMS should be accomlished.
PaynetEasy gateway returns response which contains an additional parameter redirect_url. This is the URL where merchant must redirect Customer’s browser to.
See details about response format in Payment Form Response
Merchant sends HTTP 302 redirect to Customer’s browser using URL which is obtained from the redirect_url response parameter.
Cusomer fills in payment details
Customer submits Payment Form
PaynetEasy gateway processes the transaction according to 3D or Non 3D process
When sale authorization is completed PaynetEasy gateway redirects the Customer’s browser to redirect_url request parameter provided by merchant in the original request accomplished at step 2. See details in Payment Form final redirect

Request authorization through control parameter

The checksum is used to ensure that it is a particular Merchant (and not a fraudster) that initiates the transaction. This SHA-1 checksum, the parameter control, is created by concatenation of the parameters values in the following order:

  • ENDPOINTID/ENDPOINTGROUPID
  • client_orderid
  • minimal monetary units amount (i.e. cent, penny etc.)
  • email
  • merchant_control

A complete string example may look as follows:

59I6email@client.com3E8E45B5-2-42D8-6ECC-FBF6B11B1

Encrypt the string using SHA-1 algorithm. The resultant string yields the control parameter (see Payment Form Request Parameters) which is required for request authorization. For the above-mentioned example the control will take the following value:

d02e67236575a8e02dea5e094f3c8f12f0db43d7

Order status

Merchant must use Order status API call to get the customer’s order transaction status. After any type of transaction is sent to PaynetEasy server and order id is returned, Merchant should poll for transaction status. When transaction is processed on PaynetEasy server side it returns it’s status back to Merchant and at this moment the Merchant is ready to show the customer transaction result, whether it’s approved or declined.

Status API URL

For integration purposes use staging environment sandbox.payneteasy.com instead of production gate.payneteasy.com. Status API calls are initiated through HTTPS POST request by using URL in the following format:

The End point ID is an entry point for incoming Merchant’s transactions for single currency integration.
https://gate.payneteasy.com/paynet/api/v2/status/ENDPOINTID
The End point group ID is an entry point for incoming Merchant’s transactions for multi currency integration.
https://gate.payneteasy.com/paynet/api/v2/status/group/ENDPOINTGROUPID

Order status call parameters

Status Call Parameter Description
login Merchant login name
client_orderid Merchant order identifier of the transaction for which the status is requested
orderid Order id assigned to the order by PaynetEasy
control Checksum used to ensure that it is PaynetEasy (and not a fraudster) that initiates the callback for a particular Merchant. This is SHA-1 checksum of the concatenation login + client-order-id + paynet-order-id + merchant-control. See Order status API call authorization through control parameter for more details about generating control checksum.

Status request authorization through control parameter

The checksum is used to ensure that it is Merchant (and not a fraudster) that sends the request to PaynetEasy. This SHA-1 checksum, the parameter control, is created by concatenating of the values of the parameters in the following order:

  • login
  • client_orderid
  • orderid
  • merchant_control

For example assume the following values are corresponds the parameters above:

Parameter Name Parameter Value
login cool_merchant
client_orderid 5624444333322221111110
orderid 9625
merchant_control r45a019070772d1c4c2b503bbdc0fa22

The complete string example may look as follows:

cool_merchant56244443333222211111109625r45a019070772d1c4c2b503bbdc0fa22

Encrypt the string using SHA-1 algorithm. The resultant string yields the control parameter which is required for authorizing the callback. For the example control above will take the following value:

c52cfb609f20a3677eb280cc4709278ea8f7024c
