## Overview
Reviews shape conversion — and unanswered reviews signal a brand that's not paying attention. This workflow uses the Shopify Product Reviews (or Judge.me / Loox) API to catch new reviews, generates a warm response with Claude, and gates every one behind a Slack approval before publishing.

## How it works
1. Poll the review app API every 15 minutes for new reviews.
2. Claude drafts a response grounded in: rating, review text, product name, brand voice.
3. Slack message with Approve / Edit / Skip buttons.
4. On approve, n8n posts the response back via the review app API.

## Benefits
- Review response rate goes from 20% to 100%.
- Public engagement lifts SEO and conversion.
- Merchant judgment stays in the loop — no cringe auto-replies.

## Use cases
- DTC brands with 20+ new reviews a week.
- Marketplaces where brand voice differentiates.
- Multi-brand agencies handling review ops.

## Step-by-step
### Step 1: Pick your review provider
Judge.me, Loox, and Shopify Product Reviews all have webhooks or polling APIs. Native Shopify Reviews is deprecated in 2026 — use a third party.

### Step 2: Fetch reviews
Filter to reviews without a merchant response, from the last 24h.

### Step 3: Voice guide
One paragraph: how you thank, how you handle negative reviews (own it, offer resolution off-thread), forbidden phrases.

### Step 4: Draft with Claude
System: voice guide. User: review + product context. Keep under 60 words.

### Step 5: Slack approval
Show original review, generated response, and product link. Buttons: approve/edit/skip.

### Step 6: Post + audit weekly
Sample 10 responses weekly with the brand team. Tune the voice guide from real data.

## Example
```
Review (4 stars): 'Great product, wish shipping was faster.'
Draft: 'Thank you, Ana — glad the product hit the mark. On shipping: we're piloting a faster tier in July — I'll DM you the details.'
```

## FAQs
**Can I auto-approve 5-star reviews?**

You can. Even then, 5% of them will need editing — a Slack tap is 3 seconds.

**Negative reviews?**

Always route to the merchant. Never let an LLM take a public stance on a complaint alone.

**Which model?**

Claude Sonnet — it's the strongest at brand voice out of the box. GPT-4o-mini works if cost matters more.
