1.1.1. Sale Transactions

Direct integration

General Sale Process Flow

  1. Merchant initiates a transaction by sending HTTPS POST request to the specified URL
  2. ConnPay 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.
  3. Merchant shows the Customer message like Your order is being processed. Please, wait…. Merchant starts polling ConnPay server for transaction status using paynet-order-id obtained at previous step. Status polling request and response are described in Order status asynchronous call.
  4. ConnPay Server determines if 3DS is required or not and drives the transaction authorization process as appropriate.
  5. Merchant is using single entry point for both 3DS and non-3DS Sale transactions. Actually the Merchant can not know beforehand if the sale will be driven through 3DS authorization scheme. The Merchant should use ConnPay API as described below.

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

Non-3DS Sale transaction diagram

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

@startuml
Merchant -> "ConnPay": Sale request
activate "ConnPay"
"ConnPay" --> Merchant: Order ID
"ConnPay" -> Acquirer: Process sale
activate Acquirer
Merchant -> "ConnPay": Get status by Order ID

@enduml

Sale request Customer checks out the order and Merchant sends non-3DS Sale request to ConnPay server with specified parameters described in Sale Request Parameters.
Order Id ConnPay server sends back the response with orderid. Merchant shows the customer a message like Your order is being processed. Please, wait… and starts polling for status with given orderid as described in Order status asynchronous call.
Process Sale ConnPay server forwards Sale request to bank acquirer asynchronously. The bank starts processing the transaction.
Get status by Order Id Merchant is polling for status with given orderid as described in Order status asynchronous call.
Processing result The bank responds to ConnPay server with approve or decline for requested Sale.
Final status ConnPay server returns status to Merchant through Order status asynchronous call.

3DS Sale transaction diagram

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

Checkout order Customer checks out the order on Merchant’s website
Process 3DS Sale Merchant sends 3DS Sale request to ConnPay 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 transaction is processed.
Get auth form ConnPay server requests 3DS authentication form from the Issuer Bank
Return 3DS form HTML Issuer Bank returns HTML to 3DS extra authentication form from the Issuer Bank to ConnPay server
Return 3DS response with auth form ConnPay server returns response including auth form HTML to Merchant. See details at Sale Response
Show 3DS 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 ConnPay server.
Process Sale ConnPay server forwards Sale request to bank acquirer. The bank starts processing the transaction.
Sale result The bank responds to ConnPay server with approve or decline for requested Sale
Show auto-submit order form ConnPay 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

Process Sale transaction

3DS redirect

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

Customer -> Merchant: Initiate transaction
activate Merchant

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

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

Upon completion of 3DS 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.

3DS redirect Parameter Description
status See Status List for details
orderid Order id assigned to the order by ConnPay
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 ConnPay (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 ConnPay 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 3DS 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. For amount 0.94 USD value in signing string will be 94, for 10.15 USD value in signing string will be 1015)
  • 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 ConnPay server and order id is returned, Merchant should poll for transaction status. When transaction is processed on ConnPay 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.

See more details at Statuses

Status API URL

For integration purposes use staging environment sandbox.connpay.com instead of production gate.connpay.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.connpay.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.connpay.com/paynet/api/v2/status/group/ENDPOINTGROUPID

Order status call parameters

Status call parameters Description Necessity
login Merchant login name Mandatory
client_orderid Merchant order identifier of the transaction for which the status is requested Mandatory
orderid Order id assigned to the order by ConnPay Conditional
by-request-sn Serial number assigned to the specific request by ConnPay. If this field exist in status request, status response return for this specific request. Include this parameter to get the status request with the particular transaction stage (can be used in specific cases). To get the latest transaction status, don’t include this parameter in status request Optional
control Checksum used to ensure that it is ConnPay (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 Mandatory
In most common cases, the best option is to include both client_orderid and orderid parameters to status request. Order status can be requested with only client_orderid if it’s unique to merchant and orderid is not received. If orderid is not received in response, but this response contains an error, see the received error message to get the information why transaction was not created in the system.

Order Status Response

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

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 ConnPay. 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 ConnPay 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.connpay.com instead of production gate.connpay.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.connpay.com/paynet/api/v2/sale-form/ENDPOINTID - for sale 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.connpay.com/paynet/api/v2/sale-form/group/ENDPOINTGROUPID - for sale transactions

General Payment Form Process Flow

Customer -> Merchant: Checkout
activate Merchant

alt sale
Merchant -> "ConnPay": sale-form/ENDPOINTID
activate "ConnPay"

"ConnPay" --> Merchant: status=processing
note right: redirect-url
deactivate "ConnPay"
Merchant --> Customer: Provide **redirect-url** to customer browser
deactivate Merchant
activate Customer
  loop
     Merchant -> "ConnPay": status/ENDPOINTID
     activate Merchant
     activate "ConnPay"
     "ConnPay" --> Merchant: status=processing
     deactivate Merchant
     deactivate "ConnPay"
  end

Customer -> Customer: Input cardholder data
Customer -> "ConnPay": Submit form
deactivate Customer
activate "ConnPay"
"ConnPay" -> "ConnPay": Processing

"ConnPay" --> Customer: Redirect to **redirect_url**
deactivate "ConnPay"
activate Customer

Customer -> Merchant: Return to the Shop
deactivate Customer
activate Merchant
alt status
     Merchant -> "ConnPay": status/ENDPOINTID
     activate "ConnPay"
     "ConnPay" --> Merchant: Final status
     deactivate "ConnPay"
  else callback
   "ConnPay" --> Merchant: Callback with final status
deactivate Merchant
end

Checkout – Customer proceeds to order checkout.
Merchant initiates a transaction by sending HTTPS POST request to the specified URL. It should be /sale-form/ENDPOINTID if SMS transaction should be accomplished.
ConnPay 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.
Customer fills in payment details and submits the Payment Form.
ConnPay gateway processes the transaction according to 3D or Non 3D process.
When sale authorization is completed ConnPay 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. For amount 0.94 USD value in signing string will be 94, for 10.15 USD value in signing string will be 1015)
  • 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 ConnPay server and order id is returned, Merchant should poll for transaction status. When transaction is processed on ConnPay 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.

See more details at Statuses

Status API URL

For integration purposes use staging environment sandbox.connpay.com instead of production gate.connpay.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.connpay.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.connpay.com/paynet/api/v2/status/group/ENDPOINTGROUPID

Order status call parameters

Status Call Parameter Description Necessity
login Merchant login name Mandatory
client_orderid Merchant order identifier of the transaction for which the status is requested Mandatory
orderid Order id assigned to the order by ConnPay Conditional
control Checksum used to ensure that it is ConnPay (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 Mandatory
by-request-sn Serial number assigned to the specific request by ConnPay. If this field exist in status request, status response return for this specific request. Include this parameter to get the status response with the particular transaction stage (can be used in specific cases). To get the latest transaction status, don’t include this parameter in status request Optional
In most common cases, the best option is to include both client_orderid and orderid parameters to status request. Order status can be requested with only client_orderid if it’s unique to merchant and orderid is not received. If orderid is not received in response, but this response contains an error, see the received error message to get the information why transaction was not created in the system.

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 ConnPay. 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
