P24
Accept P24 payments in your online store.
P24 is a trusted online payment solution, allowing secure transactions for customers in Poland. Integrate P24 seamlessly using the emerchantpay P24 API across the supported payment platforms.
| Payment method | Countries/regions | Supported currencies |
|---|---|---|
| Bank transfer | Poland | PLN, EUR |
Prerequisites
To integrate with P24, connect to the emerchantpay payment gateway using the emerchantpay P24 API. You should have a working knowledge of web programming languages, HTTP methods in XML and JSON formats, and UTF8 encoding. Use the emerchantpay Payment Gateway SDK libraries with code samples to integrate with the payment gateway in a range of languages.
For a solution that requires less development overhead, accept P24 payments through the emerchantpay Web Payment Form (WPF). Contact your Account Manager and tell them you want to accept P24 through the WPF, and refer to the emerchantpay Payment Gateway API WPF documentation.
1. Create a P24 payment request
To submit a payment using P24, create a payment request to the emerchantpay payment gateway. Specify p24 as the transaction_type.
Example of passing a P24 transaction request:
<payment_transaction>
<transaction_type>p24</transaction_type>
<transaction_id>119643250547501c79d8295</transaction_id>
<usage>40208 concert tickets</usage>
<remote_ip>245.253.2.12</remote_ip>
<return_success_url>http://www.example.com/success</return_success_url>
<return_failure_url>http://www.example.com/failure</return_failure_url>
<notification_url>https://www.example.com/notifications</notification_url>
<amount>1000</amount>
<currency>PLN</currency>
<customer_email>jsmith@example.com</customer_email>
<customer_phone>+1987987987987</customer_phone>
<billing_address>
<first_name>John</first_name>
<last_name>Smith</last_name>
<address1>ul. Burgaska 12</address1>
<zip_code>00001</zip_code>
<city>Warszawa</city>
<state>Mazowsze Province</state>
<country>PL</country>
</billing_address>
</payment_transaction>
2. Receive a response
You will receive a Success or Error response to your payment request.
Example of a Success response:
<payment_response>
<transaction_type>p24</transaction_type>
<status>pending_async</status>
<unique_id>3f760162ef57a829011e5e2379b3fa17</unique_id>
<transaction_id>119643250547501c79d8295</transaction_id>
<redirect_url>https://staging.gate.emerchantpay.net/redirect/to_acquirer/649e1ff35c61</redirect_url>
<mode>live</mode>
<timestamp>2024-03-25T13:53:06Z</timestamp>
<descriptor>Acme Co.</descriptor>
<amount>1000</amount>
<currency>PLN</currency>
<technical_message>Transaction successful!</technical_message>
<message>Transaction successful!</message>
<sent_to_acquirer>true</sent_to_acquirer>
</payment_response>redirect_url to redirect your customer to authorise the payment with P24. See the emerchantpay P24 API documentation for the complete list of P24 response parameters and code samples.
Asynchronous notification
Because the P24 payment transaction is asynchronous, the result of your customer’s payment is sent as a separate HTTP POST notification from the gateway to the notification_url that you supplied with the transaction request.
“transaction_id”: “f44f2856b5d933c04f42d1e922e30cbf”
“terminal_token”: “871bbbd2f9ce1d58dead9848ef5a24ab59a8ee94”
“unique_id”: “3f760162ef57a829011e5e2379b3fa17”
“transaction_type”: “p24”
“status”: “approved”
“signature”: “b74ed54d95589fce6f9d7a229b225fd4a925e9bc”
“amount”: “1000”status field provides you with information on the outcome of the transaction. See Transaction States for more information about transaction statuses.
Use the signature field to verify that the notification has been sent by the emerchantpay payment gateway. Each session signature is generated by combining the unique_id of the transaction and your API password, and generating a SHA-1 hash function of the combined string.
signature = SHA-1 hash value of <unique_id><API password>
| unique_id | API password | signature |
|---|---|---|
| 26aa150ee68b1b2d6758a0e6c44fce4c | 50fd87e65eb415f42fb5af4c9cf497662e00b785 | c5219b3d385e74496b2b48a549 |
| 3f760162ef57a829011e5e2379b3fa17 | 50fd87e65eb415f42fb5af4c9cf497662e00b785 | 14519d0db2f7f8f407efccc9b099 |
After you have verified the notification state and validity, render an XML page containing the transaction’s unique id to acknowledge that you have received the notification.
Example of a notification reply you use to confirm a notification:<?xml version=”1.0″ encoding=”UTF-8″?>
<notification_echo>
<unique_id>3f760162ef57a829011e5e2379b3fa17</unique_id>
</notification_echo>
3. Test your integration
Before you can accept live payments, you must test your integration in the staging environment.
- Add an item to your cart in your online store.
- Proceed to the checkout page and check out using P24.
- Follow the redirect link in the response.
- In the payment simulator, follow the instructions to simulate a transaction.
- Complete the order and verify that you are redirected to the order confirmation page.
- Log in to the Gateway Console.
- In the navigation menu, go to Payment transactions.
- Verify that the transaction appears at the top of the list and is successful.
4. Accept live payments
After you have successfully tested your P24 integration, you are ready to move to the production environment and accept live payments. Contact your emerchantpay Account Manager to get your login credentials for the production environment.
