Fix Magento API Issues for Integration

Task Brief: Fix Magento API Issues for Flutter Mobile App Integration
We need a backend Magento developer to fix two critical issues in our Magento API used by a live Flutter mobile app. The mobile app is already integrated — these are isolated issues on the API side.
You will work against a testable API and Git-connected frontend team. All integration and testing support is provided.
Issue 1: Incorrect Segmentation Key in Category Response
- The Magento API returns product segmentation key as `Shop` instead of the correct product `category` in 4 specific product cases.- This breaks face visualisation mapping in the app (e.g. Lipliner, Eyebrow, Eyeliner, Liquid Concealer).- Other categories work fine, so the issue is with inconsistent key assignment or filtering.
Expected:```json[{ "category": "#421927", "visibility": 2 }]```
Current broken response:```json[{ "Shop": "#421927", "visibility": 2 }]```
Issue 2: GiftCard/Promo Code API Returns Empty Response
- When submitting a valid promo/gift card code (e.g. `cha06061234567`) with a populated cart and valid bearer token, the API responds:```GiftCard API Response is :: []```- This occurs even when the code is active and has valid date range and amount.- We suspect the API is failing to detect the code properly or session/cart linkage is broken.
Expected:- API should return the remaining balance or validation details, not `::[]`.
Provided:- Full Magento API source access- Frontend test cases (Flutter)- Confirmed working setup for authentication and token flow- API test logs and screenshots- Git repo (Magento + Flutter branches)
Deadline:Fixes should be implemented and testable within 2–3 days. I will guide you down to code level so I know where it is even.
Please note: you are hired to deliver, not to come up with excuses and bloat timeline. The system is more than 4 years old so it is well analysed and in production.
