Security

Enterprise-grade security
by default

Every layer of CashOut is built with security in mind — from API authentication to database operations.



🔐
API Key Auth
Merchant API keys use the mk_ prefix format with 35+ character entropy. Keys never exposed in URLs.
📋
Webhook Verification
All incoming PSP webhooks are verified via JWT signature before any balance changes occur.
⚙
Atomic Balance Ops
All balance changes use SELECT FOR UPDATE transactions — race conditions are impossible by design.
🚫
High Throughput
Handles massive request volumes without breaking a sweat. Smart queue system ensures every transaction is processed correctly — no drops, no duplicates, no matter the load.
🔒
Zero IDOR
Merchant IDs are never exposed. All data access is scoped to the authenticated merchant only.
🏢
5-Node Infrastructure
Our platform runs across 5 independent servers simultaneously, ensuring maximum stability and processing speed. In the event of a DDoS attack or server-side failure, traffic is instantly rerouted to the next available node — zero downtime for your payments.
