[gaius01]

Close #21

In this project, we successfully resolved critical merge conflicts and implemented a full-featured, real-time Webhook Logs Dashboard.

Here is a breakdown of exactly what was accomplished:

1. Conflict Resolution & Infrastructure
   Fixed Package Dependencies: Resolved version mismatches in package-lock.json and added missing ESLint dependencies to
   package.json
   to align the backend with the main branch.
   Prisma Database Setup: Updated the database schema to include a new WebhookLog model and linked it to the
   Merchant
   model.
   Environment Configuration: Created
   .env
   files for both the backend and frontend to ensure they can communicate locally.
2. Backend API Implementation
   We built the engine that powers the logs:

Log Retrieval: Created an endpoint to fetch webhook logs with advanced filtering (status, event type, and search).
Manual Retries: Implemented a service to allow merchants to manually trigger a webhook retry.
Testing Tool: Built a "Test Webhook" service that generates mock events so you can verify your integration without needing real transactions.
3. Frontend Dashboard Integration
We transformed the static UI into a live application:

Real Data Fetching: Updated the
useWebhooks
hook to replace mock data with real fetch calls to your API.
Robust UX: Added loading skeletons, error handling for failed API calls, and a manual "Refresh" button.
Testing Interface: Integrated the Webhook Testing Tool directly into the dashboard header, allowing for one-click testing.
4. Stability & Polish
Hydration Error Fix: Resolved a common Next.js issue by adding suppressHydrationWarning to the root layout, preventing browser extensions (like LanguageTool) from crashing the page.
Git Cleanup: Synchronized the work across branches and performed a final push to your
Webhook
branch, ensuring all changes are safe and ready for review.
