Callback Notifications
An integral part of the mechanism for receiving notifications about transactions on the wallet. This important tool allows online services to automatically receive information about changes in the wallet balance in real time. When a payment is received on the wallet or another event occurs, the system activates a callback - a request sent to an external server. This server processes the request and sends back the necessary information, allowing services to instantly respond to balance changes. Callback notifications provide fast and reliable communication between wallets and services, reducing delays and ensuring data is up to date.
