Before accepting money from the buyer on the account, the payment gate can call the merchant script Check URL using the Request Method
Check URL on the merchant side must be public, without authorization
{{project}} sends information about the number and properties of the order and waits for a response. Failure to respond within the specified time is considered as a refusal to pay.
The Check URL script is called only if this option was enabled in the merchant settings
Merchant response to check_url:
ok - payment accepted
rejected - payment refusal
error - error in data interpretation
If Check URL is empty at the moment of payment initialization or not specified at the moment of payment initialization, and is set to empty in the merchant settings, then the step of checking the ability to make a payment is skipped and it is considered that the merchant agrees to accept the payment
