AngularJS Razorpay & Inventory Integration

My real-estate portal is built on AngularJS and I want to add two upgrades that will let us monetise and keep listings fresh.

1. Razorpay payment gateway
I already hold the Razorpay API documentation and keys, so the job is to wire the full client-side flow and the server-side callback handler. Transactions must post back to our database, update order status, and show a clear success/failure message to the user.

2. Third-party property inventory feed
Our listings need to sync with an external real-estate inventory API. You will create the service that fetches new or updated property data, maps it to our existing models, and pushes it into the site on a schedule (or webhook if the source supports it). De-duplication and basic error logging are expected.

Deliverables
• Clean, well-commented AngularJS code for Razorpay checkout and callback handling
• A reusable service/module that imports the property feed and exposes CRUD endpoints
• Brief deployment notes so I can plug your work into our staging and production environments

Acceptance criteria
• Successful Razorpay transactions reflected in the database and UI without page reloads
• Property feed runs automatically and shows the new listings in the front end
• No regression bugs introduced to existing features

If you have solid AngularJS experience and have touched Razorpay or similar gateways before, this should be a straightforward assignment. I’m ready to share repo access and the full API docs as soon as we start.
