The Amazon SP-API sandbox environment has limited functionality:
- Catalog APIs: Many catalog endpoints return "InvalidInput" even with correct parameters
- Orders APIs: Order-related endpoints appear to have limited test data
- Seller APIs: Basic seller information endpoints work correctly
This is normal behavior for Amazon's sandbox environment, which provides limited test scenarios.
To access full SP-API functionality:
-
Generate Production Refresh Token:
- Go to Seller Central → Settings → User Permissions → Third-party developer and apps
- Find your SP-API application
- Generate a Production refresh token (not sandbox)
-
Update Configuration:
# In your .env file: AMAZON_SANDBOX=false AMAZON_REFRESH_TOKEN=your_production_token_here -
Test Production Environment:
npx tsx debug/test-working-api.ts
