Building a Reliable Event-Driven Payment Service With XRP Ledger
by Emma Clapp Receiving a transaction notification is only the first step. Production software still has to decide whether that event is safe to turn into application state. A WebSocket callback can arrive in milliseconds. What happens afterward is harder. The XRP Price may be the public-facing metric most people associate with the asset, but developers integrating the XRP Ledger have a different concern. A long-running service has to detect transactions, determine whether their outcomes are final, and update local application state without acting twice or acting too soon. When an XRPL Event Actually Means Something A WebSocket connection can save an application from constantly polling for new activity. On a Linux service, that means keeping the connection open and listening for the XRP Ledger events the application cares about. The XRP Ledger’s subscribe documentation explains how applications can listen for ledger activity, transactions, and account-related events. The transactions s
