}

merchant_id

The merchant id given to you by Paytrail when you make the contract. Defaults to the test merchant account.

merchant_secret

The merchant secret given to you by Paytrail. Defaults to the test merchant account.

test_transaction

Set to 1 to mark the mode as a test. In that case the test merchant account of Paytrail is used and no real money is transferred. Intended for testing.

debug

Set to 1 to get debug warnings. Defaults to 0, no debug.

content

Set the content to be sent to Paytrail API. All content must be in accordance to http://docs.paytrail.com/ field specs, as a Perl data structure.

submit

Submits the content to Paytrail API. Populates is_success, url, server_response_json, server_response, result_code, error_message, token and order_number.

is_success

Populated when you call submit. Status of the submission.

url

Populated when you call submit. This is the URL the user should go to to make the payment.

token

(Nice-to-have) Populated when you call submit and the submission is succesful.

order_number

(Nice-to-have) Populated when you call submit and the submission is succesful.

server_response_json

(Nice-to-have) Populated when you call submit and the submission is succesful.

server_response

(Nice-to-have) Populated when you call submit. The entire unprocessed response content.

result_code

(Nice-to-have) Populated when you call submit. The HTTP status code of the reply.

error_message

Populated when you call submit and the submission is not succesful. Contains the error message from Paytrail.

verify_return

When the end-user has completed the payment he will return to your specified RETURN_ADDRESS, CANCEL_ADDRESS or PENDING_ADDRESS. Before you process the returning any further you must check that the parameters given to this address have the correct checksum.

This method verifies the checksum and returns true or false stating if the checksum matched or did not.

After you know that the checksum matched you can mark the payment as paid (if returned to RETURN_ADDRESS), as pending (if returned to PENDING_ADDRESS) or canceled (if returned to CANCEL_ADDRESS).

Also your NOTIFY_ADDRESS should call verify_return first to verify the checksum and only if the verification is passed proceed with the information received.

port

The port where the submission is sent to. Defaults to 443.

server

The server host name where the submission is sent to. Defaults to payment.paytrail.com.

path

The URL path where the submission is sent to. Defaults to /api-payment/create.

api_version

The REST API version of Paytrail. Defaults to 1.

SECURITY

Don't allow user to set the test_transaction to true! If the user can set it to true when returning he will get his payment registered as processed.

Don't allow user to set the 'type' parameter of verify_return.
