Payment Handler
Last updated
Last updated
As the payment is made, we notify the store's platform of the payment status by consistently sending GET requests to the handler's URL.
The domain in the payment handler must completely match the one you add to our system as a project
CHECK: checking the possibility of providing the service to the subscriber, the request is sent before the payment is made. You must confirm that the system is ready (check whether the payment amount is correct, whether the account exists in the database, etc.)
PAY: notification of successful debiting, you must provide the service to the subscriber. If any error occurs at this stage (e.g., the database is inaccessible), the payment gets the "not completed" status. After the problem is resolved, you can repeat the payment in the statistics interface. Money is credited to the partner's balance regardless of the handler's response
PREAUTH: notification in case of payments with pre-authorization when funds are successfully blocked. Important Note! You should not provide the service or give the goods to the payer upon receipt of such notification. The funds should be debited and services should be provided when confirmPayment is completed
ERROR: payment error at any stage. If an error is caused by an empty/error response from the partner server, the request will not be sent. Please note that this status is not final and there may be situations when the ERROR request may be followed by a PAY request
