API Payment Methods (1.0)

create

Access is protected by IP address validation and the integrity of transmitted data is ensured using the HTTPS protocol. The step of creating payments is optional, but it is advisable to implement it in case you require the certainty of secure payment creation. It is possible to skip the implementation of this step if you do not need to identify individual payments in the system, but only require information that someone has paid you a certain amount. This is suitable, for example, when implementing donations or recharging funds to a customer's virtual account, where you are only interested in who recharged what amount, but you do not need to differentiate individual recharges or limit recharges to a minimum amount. However, for a classic e-shop, where you pay for specific goods, it is inappropriate to skip this step. The merchant uses HTTP requests to create payment transaction. Payment attributes including unique payment reference numbers are sent as POST parameters via HTTP protocol. Communication is only between the Merchant’s server and the payment gateway server. It is invisible to payer and the payer cannot change the payment parameters. The payment gateway server responds by sending a unique payment transaction identifier – transaction ID (Comgate system identifier) and URL to which to redirect the payer

The payment gateway server responds only if the payment is created in a background. All parameters are urlencoded, as in the case of an HTTP request. If the payment is created through redirection (the prepareOnly parameter is 'false'), then the payment gateway server directly redirects the Payer to the appropriate URL or displays an error message.

Choice of payment method
Within the shopping process on the e-shop, it's possible to display a selection of payment methods to the payer, and based on their selection, initiate a payment with a specific method. When the payer is presented with the payment gateway, the pre-selected payment method will be automatically displayed. Setting the chosen payment method is possible by filling in the 'method' parameter. Through this parameter, payment methods can also be filtered differently.

Pre-authorization
The payment gateway allows to enter, confirm and cancel pre-authorizations of card payments. The payment is created in the standard way, it is only necessary to specify the parameter preauth = true. After Payer enters data at the payment gateway, the corresponding amount is reserved on his payment card. Depending on the result of this operation, it goes either to the special AUTHORIZED state or, in the case of rejection, to the CANCELED state. This result is reported in the background according to the usual procedure described above.
In order for the money to be actually withdrawn, the e-shop calls the function to confirm the pre-authorization. If the money is to be released (eg it is not possible to meet the conditions of the purchase contract), the e-shop calls the function to cancel the pre-authorization.

cancel

Storno of payment
If the order in the e-shop has been canceled and the transaction is not to be completed by the payer, it is possible to use the storno of payment. Unlike a refund, the payment must be in the pending state.
Due to the speed of payment, the payment may already be paid, in which case an error will be displayed and the refund method must be used.

recurring

Recurring payments, remembering card details
The payment gateway allows you to enter recurring payments, that is, one-click payments. The first (initial) payment takes place through a standard process with redirection to the payment gateway, subsequent payments already take place completely in the background. The system thus allows the payer to pay within a few seconds without having to fill in information about the payment card.
This functionality is available on request. In the case of recurring payments at the beginning, we create an initial payment, which is created as a regular payment, only the request contains an additional parameter initRecurring - method create. Subsequent recurring payments are already created using the recurring method and are linked to the Comgate ID of the initiating transaction. This ID must be tied to a specific Payer in the Client's system.
After creating a recurring payment, the Payer is not redirected to the payment gateway, because the whole process takes place in the background, the Client is only given the status of the payment, and he then displays this status to the Payer.

Subsequent recurring payments
Creating a second and subsequent recurring payment to the payment gateway is only possible in the case of accepting cards for e-shops that have the service enabled.The first (initial) payment is made in the standard way (see Creating a payment). The process of creating a second and each subsequent payment takes place completely in the background, these payments are tied to the initiator via the Comgate ID of the initiation payment. This ID must be in the request in the initRecurringId parameter. The payer is shown the payment status in the e-shop system as a result.

All parameters are urlencoded, as in the case of an HTTP request to create a standard payment. The answer contains the code parameter, according to which the e-shop determines what result the payer will display. Code = 0 means success, the payment was created, any other code means an error and therefore no payment was created.

Recurring payments
Recurring payments with a predefined amount and period (eg monthly, weekly, etc.) can be made using the Recurring Payments service, which is described in the previous paragraphs.
Test recurring payments created with the e-mail 'recurring.cancelled@comgate.cz' will have all subsequent payments (apart from the initial one) tagged as CANCELLED (unpaid)
