when making requests to the Import Service API.

---

Task 7.3 - Frontend Authorization

• Updated CSVFileImport.tsx to send Authorization: Basic <token>
  header with every /import request
• Frontend reads authorization_token from browser localStorage
• Fixed Import Service API URL in apiPaths.ts

---

Files Changed:

• ✅ src/components/pages/admin/PageProductImport/components/CSVFileImport.tsx - UPDATED
• ✅ src/constants/apiPaths.ts - UPDATED (fixed import API URL)

---

How Authorization Works:

1. User sets token in browser localStorage:

localStorage.setItem('authorization_token', btoa('github_username:TEST_PASSWORD'))
2.Frontend reads token from localStorage on every import request
3.Token is sent as Authorization: Basic <token> header
4. Backend basicAuthorizer Lambda validates the token

localStorage.setItem('authorization_token', btoa('github_username:TEST_PASSWORD'))

Step 2 - Go to Import page:

http://localhost:3000/admin/products
Step 3 - Select a CSV file and click Upload

Expected Results:

✅ With correct token → file uploads successfully to S3
❌ With wrong token → 403 Forbidden
❌ With no token → 401 Unauthorized
