Current Limitations
Read-only: Customers cannot submit reviews from within the app.
No PLP star ratings: Ratings display on the PDP only.
Stamped's loyalty and rewards features are managed separately and are not part of this reviews integration.
Troubleshooting
Reviews not appearing: Double-check all three credentials are entered correctly with no extra spaces. The most common cause is a mistyped key.
Cannot find API Keys: Go to Stamped Dashboard > Settings > API Keys and confirm you are in the Reviews Integrations section (not the general API section).
