Controlled account, data, billing, and payment workflows.
GPSEWA keeps the public website separate from account access, customer data, provider credentials, payment operations, automated notifications, and backup workflows.
Public boundary
What the browser can and cannot touch
Console users
Email login, OTP verification, merchant roles, and reviewable account activity.
Customer records
Sensitive profile, billing, KYC, and payment references stay behind backend API boundaries.
Server integrations
API keys, idempotency keys, callback URLs, and signed webhooks for merchant systems.
Merchant operations
Plan creation, invoice changes, exports, reconciliation views, and provider-status actions are logged.
Platform controls
Customer-facing security capabilities
These are the trust features merchants should understand publicly. Private implementation details, credentials, and provider secrets stay out of the website.
Email login, account recovery, and verified console access for merchants and operators.
Supports email OTP and phone OTP flows for sensitive account actions without exposing credentials in the public website.
Protected storage boundary for merchant, customer, KYC, payment, and billing records.
Public pages do not store sensitive records. Access is scoped through GPSEWA backend APIs and merchant permissions.
Separate login email and billing or notification email per customer where operations need it.
Useful for finance teams that want invoices, receipts, dunning, and account security notices routed differently.
Create plans, prices, subscriptions, invoices, retries, and customer billing workflows.
Billing operations are access-controlled and logged so finance teams can review changes to plans and invoices.
Transactional emails for invoices, payment failures, verification, refund updates, and account events.
Notification delivery is handled by backend services, not by browser code or public pages.
Backup and restore workflows for customer, payment, billing, and operational records.
Designed so recovery procedures are reviewable and separated from day-to-day payment operations.
Boundary model
Public website, console access, APIs, and protected records stay separated.
The public site explains GPSEWA and sends users through GPSEWA-owned signup. Account login, customer data, billing automation, payment verification, provider credentials, and backups are handled behind GPSEWA backend controls.

Security checklist
Core controls GPSEWA is designed around for account access, data protection, API integrations, billing operations, and payment workflows.
Webhook security
Merchant servers should verify GPSEWA signatures before fulfilling orders, releasing access, or updating payment state.
Fulfillment warning
Never fulfill an order, activate a subscription, or update payment state from an unsigned or unverified webhook.
