Use POST and form parsing for epay notify/return routes, persist epay orders before provider calls with expiry on failure, and ensure notify handlers retry correctly.
Restrict subscription-first fallback to insufficient-subscription errors and log refund failures after retries to avoid silent quota drift.
Create the subscription order before initiating epay payment and expire it if the provider call fails, preventing orphaned transactions and improving reconciliation.
Standardize SubscriptionRequestEpay error responses via ApiErrorMsg for a consistent schema.
Return "fail" on non-success trade statuses in the epay webhook to preserve retry behavior.
Ensure Epay webhook acknowledges success only after order completion, returning fail on processing errors to allow retries. Redirect subscription payment returns to the subscription page instead of top-up for correct user flow.
Improve subscription payment safety and data integrity by handling user/URL lookup failures, fixing Stripe subscription mode, persisting quota reset fields, and correcting subscription delta accounting and DB timestamp casting. Refine the UI with stricter custom duration validation, accurate currency rounding, conditional Epay labeling, rollback on preference update failure, and shared subscription formatting helpers plus clearer component naming.
Add per-plan purchase limits with backend enforcement and UI disable states.
Expose limit configuration in admin plan editor and show limits in plan tables/cards.
Refine subscription UI tags with unified badge style and streamlined “My Subscriptions” layout.
Replace separate enable/disable flows with a single PATCH API that updates the enabled flag.
Update frontend hooks and table actions to call the unified endpoint and keep UI behavior consistent.
Introduce a minimal admin controller handler and route for the status update.
Apply consistent code formatting across the entire codebase using
gofmt and lint:fix tools. This ensures adherence to Go community
standards and improves code readability and maintainability.
Changes include:
- Run gofmt on all .go files to standardize formatting
- Apply lint:fix to automatically resolve linting issues
- Fix code style inconsistencies and formatting violations

Implement a new subscription-based billing model alongside existing metered/per-request billing:
Backend:
- Add subscription plan models (SubscriptionPlan, SubscriptionPlanItem, UserSubscription, etc.)
- Implement CRUD APIs for subscription plan management (admin only)
- Add user subscription queries with support for multiple active/expired subscriptions

- Add billing preference settings (subscription_first, wallet_first, etc.)
- Enhance usage logs with subscription deduction details
Frontend - Admin:
- Add subscription management page with table view and drawer-based edit form
- Match UI/UX style with existing admin pages (redemption codes, users)
- Support enabling/disabling plans, configuring payment IDs, and model quotas
- Add user subscription binding modal in user management
Frontend - Wallet:
- Add subscription plans card with current subscription status display
- Show all subscriptions (active and expired) with remaining days/usage percentage
- Display purchasable plans with pricing cards following SaaS best practices
- Extract purchase modal to separate component matching payment confirm modal style
- Add skeleton loading states with active animation
- Implement billing preference selector in card header
- Handle payment gateway availability based on admin configuration
Frontend - Usage Logs:
- Display subscription deduction details in log entries
- Show step-by-step breakdown of subscription usage (pre-consumed, delta, final, remaining)
- Add subscription deduction tag for subscription-covered requests
