Security & trust

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.

GPSEWA account access

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.

Customer data vault

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.

Customer contact controls

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.

Billing plan controls

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.

Automated notifications

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 recovery

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.

Frontend never stores provider secrets or payment credentials
GPSEWA account access handles login, verification, OTP, and account recovery
Email and phone OTP can protect sensitive account actions
Scoped API access separates server integrations from console users
Customer and payment records stay behind backend data boundaries
Automated email notifications are sent from controlled backend workflows
Webhook signatures are verified before fulfillment
Money-moving actions are logged and reviewable
Billing plan, price, and invoice changes can be audited
Backup and restore workflows are separated from public website code

Webhook security

Merchant servers should verify GPSEWA signatures before fulfilling orders, releasing access, or updating payment state.

HMAC-SHA256 signature header
Timestamp included to reduce replay risk
Retry-safe event delivery
Webhook events visible in integration logs

Fulfillment warning

Never fulfill an order, activate a subscription, or update payment state from an unsigned or unverified webhook.

Audit log preview

Security-sensitive account, billing, API, webhook, refund, and reconciliation actions should remain attributable and reviewable.
