CLONE — YOU CAN REBUILD THE FEATURE
FeedbackExpress is fundamentally a wrapper around the Amazon SP-API Solicitations endpoint and eBay Messaging API. You are paying for their pre-approved developer tokens, TOS compliance maintenance, and ready-made web app. The actual code—querying delivered orders and executing the standard 'Request a Review' API payload—is simple enough to write in a weekend. However, unless you already hold an approved Amazon SP-API developer key with direct Restricted Data Token (RDT) access, building your own system will stall at Amazon's developer approval and Data Protection Policy (DPP) audit process.

Why this verdict
The underlying logic is just a scheduled cron task calling Amazon's Solicitations API for delivered orders. However, obtaining approved developer access for Amazon SP-API and maintaining compliance with Amazon Data Protection Policy is a major barrier for direct self-hosting.

The one-shot build prompt
Paste it into your agent of choice. Nothing else needed.
Build an open-source alternative to FeedbackExpress for automated Amazon and eBay review requests.
1. DATA MODEL & SCHEMA:
- Create PostgreSQL database with tables:
- `marketplaces`: id, platform ('amazon'|'ebay'), region, credentials_json (encrypted LWA tokens / eBay OAuth keys).
- `orders`: id, marketplace_id, external_order_id, delivery_date, status, buyer_id, sku_list (jsonb), review_requested_at (timestamp, nullable), request_status ('pending'|'sent'|'failed'|'skipped').
- `suppression_list`: id, type ('sku'|'buyer_id'), value, reason.
- `settings`: delay_days_after_delivery (default 5), auto_request_enabled (boolean).
2. INTEGRATION ENGINE:
- Implement Amazon Selling Partner API (SP-API) LWA auth flow with auto token refresh.
- Implement SP-API Solicitations API endpoint `createStatutoryRequest` for Amazon order IDs.
- Handle rate limiting: execute requests adhering to Amazon's leaky bucket rate limits (e.g., 1 request/sec burst to 5) with exponential backoff.
3. SCHEDULER LOGIC:
- Create a daily background worker (Node-cron or BullMQ):
a. Query `orders` delivered between (NOW - delay_days) and NOW where `review_requested_at` IS NULL.
b. Exclude any order containing SKUs or buyer IDs matching entries in `suppression_list`.
c. For Amazon orders, invoke `createStatutoryRequest` via SP-API.
d. Record exact status, response code, and set `review_requested_at` to NOW on success.
4. DASHBOARD UI:
- Next.js (Tailwind + Shadcn) administrative dashboard.
- Summary stats: Total requests sent this month, success rate, pending queue count.
- Orders table displaying order ID, marketplace, delivery date, request status, and manual retry button.
- Suppression List management interface to add/remove SKUs and buyer IDs.
5. OUT OF SCOPE:
- Custom email templating (use Amazon official statutory review request API to remain 100% TOS compliant).
- Direct email server handling / SMTP.$ each button prefixes agent-specific run instructions · build your own product, never copy proprietary code, trademarks or designs

Why people still pay — the real moats
Moats
- — Approved Amazon SP-API developer registration and PII compliance clearance
- — Compliance guardrails built around strict marketplace Terms of Service
- — Pre-built OAuth connections across all global Amazon regions
Hard parts
- — Implementing LWA (Login with Amazon) authentication and handling Restricted Data Tokens
- — Strict compliance with Amazon Data Protection Policy (DPP) encryption requirements
- — Managing Amazon SP-API rate limits (leaky bucket algorithm) on Solicitations calls
- — Normalizing order status definitions across Amazon SP-API and eBay Trading API
- — Passing Amazon's annual SP-API security and vulnerability assessment
- — Risk of seller account suspension if custom automated messages breach Amazon TOS
- — Maintaining ongoing API schema updates when Amazon deprecates endpoints
- — Managing opt-outs and buyer communication preferences across channels

FAQ
+Can I really replace FeedbackExpress with an AI-generated app?
REPLACEABLE LOGIC, BUT AMAZON SP-API COMPLIANCE IS A BOTTLENECK. The underlying logic is just a scheduled cron task calling Amazon's Solicitations API for delivered orders. However, obtaining approved developer access for Amazon SP-API and maintaining compliance with Amazon Data Protection Policy is a major barrier for direct self-hosting. An MVP takes roughly 1 week; matching the product properly is closer to 3-6 months, due to Amazon SP-API security audits and PII compliance.
+How long does it take to rebuild FeedbackExpress?
A usable internal version: 1 week. A version you would sell or bet a business on: 3-6 months, due to Amazon SP-API security audits and PII compliance, mostly spent on implementing lwa (login with amazon) authentication and handling restricted data tokens.
+What do you actually lose by leaving FeedbackExpress?
Pre-approved Amazon Selling Partner API (SP-API) tokens Automatic compliance updates for changing Amazon Communication Guidelines Instant turnkey auth flows for global Amazon and eBay marketplaces
+Is it legal to build a FeedbackExpress alternative?
