Interaction diagram
Payment processing by using the Przelewy24 method involves the merchant's web service, one of ecommpay interfaces, the ecommpay payment platform, and technical facilities of the Przelewy24 service.
Operations support
Various platform interfaces can be used to process payments and perform operations using the Przelewy24 method. Purchases can be processed by using Payment Page, Gate and Dashboard (using payment links), refunds—by using Gate and Dashboard. At the same time, regardless of the interfaces used, the following limitations are applicable.
When working with the Przelewy24 the following limitations are applicable.
Processing scenarios
To perform a purchase by using the Przelewy24 method, you need to redirect the customer to the Przelewy24 service, while to make a refund, you need to receive a request from the customer and notify the customer about the result of the refund via the web service.
Scenarios for performing operations via the main interfaces of the payment platform correspond to those presented in the diagrams. Similarly, when additional features (such as payment links) are used, scenarios for performing operations also correspond to the specifics of those features.
Purchases by using Payment Page

- Payment Page is generated based on the project and request parameters.
- Payment Page is displayed to the customer.
- The customer selects the Przelewy24 method.
- The payment platform receives the request for processing the payment by using the Przelewy24 method.
- The payment platform processes the request and sends it to the Przelewy24 service.
- The request is processed on the Przelewy24 service side.
- The data for redirecting the customer to the Przelewy24 service is sent from the Przelewy24 service to the payment platform.

Information about the formats of requests and callbacks used for processing payments by using the Przelewy24 method via Payment Page is presented further in this section; general information about working with the Payment Page API is presented in Interaction concepts.
Request format
There are several things you need to consider when sending purchase requests by using the Przelewy24 method:
- The following parameters required for any payment must be specified:
project_id
—project identifier obtained from ecommpay during integrationpayment_id
—payment identifier unique within the projectpayment_currency
—payment currency code in the ISO-4217 alpha-3 formatpayment_amount
—payment amount in the smallest currency unitcustomer_id
—customer identifier unique within the project
- The following parameters required for any payment must be specified:
project_id
,payment_id
,payment_currency
,payment_amount
,customer_id
. - To open Payment Page, specify the language code in the
language_code
parameter in the request for opening. For more information, see Interface language support. - These parameters also must be specified:
customer_email
—customer email addresscustomer_first_name
—customer first namecustomer_last_name
—customer last name
- If you need to have the payment form displayed with the Przelewy24 method selected, set the
force_payment_method
parameter toprzelewy24
. - Additionally, any other parameters available for working with Payment Page can be used (details).
- After all target parameters are specified, generate a signature (details).
Thus, a correct request for opening the payment form using the Przelewy24 method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer information, language code and signature.

Callback format
The Przelewy24 method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks.
The following is the example of a callback with information about a 100,00 PLN
purchase made in the 238
project.

- The customer receives the payment result information from the web service.
Information about the formats of requests and callbacks used for processing payments by using the Przelewy24 method via Gate is presented further in this section. General information about working with the Gate API is presented in Interaction concepts.
Request format
There are several things you need to consider when sending purchase requests by using the Przelewy24 method:
- To initiate each purchase, send a separate POST request to the
/v2/payment/online-banking/przelewy24/sale
endpoint. This endpoint belongs to the group /v2/payment/online-banking/{payment_method}/sale. - Each request must include the following objects and parameters:
- Object
general
—general purchase information:project_id
—project identifier obtained from ecommpay during integrationpayment_id
—payment identifier unique within the projectsignature
—request signature generated after all required parameters are specified (details—in the Signature generation and verification) (details)
- Object
payment
—payment information:amount
—payment amount in the smallest currency unitcurrency
—payment currency code in the ISO-4217 alpha-3 format
- Object
customer
—customer information:id
—customer identifier unique within the projectip_address
—customer IP address relevant for the initiated payment
- Object
return_url
—contains the URLs to which customer is redirected during or after payment processing:success
—URL for redirecting a customer during purchase processing
- Object
- Additionally, it is recommended to specify the following objects and parameters:
- Object
customer
—customer information:email
—customer email addressfirst_name
—customer first namelast_name
—customer last name
If any of these parameters are missing, the payment platform may send the list of missing parameters in a callback requesting additional information submission (details are available in Submission of additional payment information).
- Object
- Additionally, any other parameters included in the specification can be used.
Thus, a correct purchase request by using the Przelewy24 method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer information, URL for redirection and signature.

Formats of intermediate callbacks for customer redirection
Each payment made with the Przelewy24 method requires redirection of customers from the merchant's web service to the Przelewy24 service. To redirect a customer it is necessary to receive an intermediate callback from the payment platform and use the information included in the redirect_data
object. The format of such callbacks is standard (details), and the following objects and parameters are included in the redirect_data
object:
body
—object with data to be sent in the request bodymethod
—parameter specifying the HTTP method for sending the request (GET
orPOST
)url
—parameter containing a link for redirection
"redirect_data": { "body": [], "method": "GET", "url": "https://p24.de/p24?tx=421417103&rs=uv333db1260e2" }
Final callback format
The Przelewy24 method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks.
The following is the example of a callback with information about a 100,00 PLN
purchase made in the 238
project.

Analysis of payments results
To analyse information about payments made with the Przelewy24 method and other methods, you can use:
- Dashboard interface toolkit with various lists and analytic panels.
- Reports in CSV file format, available via the Reports section (one-time and periodically).
- Data in JSON format, sent by program requests to a specified URL available by using the Data API interface.
If you have any questions, refer to the documentation (Dashboard and Using Data API) and ecommpay technical support.
