Woo Refund Rate Analysis

woo-refund-rate-analysis

Purpose

Compute refund rates for WooCommerce orders segmented by product, product category, or time period. Identifies products with abnormally high return rates that warrant quality investigation. Read-only.

Prerequisites

• WooCommerce store with REST API enabled
• Consumer Key with Read scope
• Minimum WooCommerce version: 3.5.0

Parameters

Authentication

WooCommerce uses OAuth 1.0a for HTTP and Basic Auth over HTTPS.

For HTTPS stores (recommended):

Authorization: Basic base64(consumer_key:consumer_secret)

For HTTP stores (development only): Use OAuth 1.0a — include oauth_consumer_key, oauth_nonce, oauth_signature, oauth_signature_method=HMAC-SHA1, oauth_timestamp, oauth_version=1.0

Never log or output consumer_key or consumer_secret values.

See docs/​AUTHENTICATION.md for full setup instructions.

Safety

Read-only skill — no mutations are executed. Safe to run at any time.

Workflow Steps

Step 1 — Fetch completed orders

GET /​wp-json/​wc/​v3/​orders
  ?status=completed&after=<date_after>T00:00:00Z&before=<date_before>T23:59:59Z&per_page=100&page=1

Aggregate units sold and revenue per product_id from line_items.

Step 2 — Fetch refunded orders

GET /​wp-json/​wc/​v3/​orders
  ?status=refunded&after=<date_after>T00:00:00Z&before=<date_before>T23:59:59Z&per_page=100&page=1

Aggregate refunded units and amounts per product_id from line_items.

Step 3 — Compute rates

refund_rate = refunded_units / (sold_units + refunded_units) * 100

Flag products where refund_rate > high_rate_threshold.

Step 4 — Export

API Endpoints Used

GET  /​wp-json/​wc/​v3/​orders                — completed and refunded order scan
GET  /​wp-json/​wc/​v3/​orders/​{id}/​refunds   — detailed refund line items

Pagination Strategy

WooCommerce REST API uses page/​per_page pagination (not cursor-based).

Standard pattern:

page = 1
while True:
  response = GET /​endpoint?per_page=100&page=page
  process(response)
  if len(response) < 100: break
  page += 1

Maximum per_page is 100 for most endpoints. The X-WP-Total and X-WP-TotalPages response headers report totals. Always read X-WP-TotalPages on the first request to estimate job size.

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

STARTUP:

╔══════════════════════════════════════════╗
║  SKILL: woo-refund-rate-analysis         ║
║  STORE: <store_url>                      ║
║  TIME:  <ISO-8601 UTC>                   ║
║  MODE:  READ-ONLY                        ║
╚══════════════════════════════════════════╝

PER-OPERATION (emit after each API call batch):

[N/​TOTAL] <METHOD> <endpoint> → <result_count> records | params: <key>=<val>

COMPLETION (human format):

╔══════════════════════════════════════════╗
║  COMPLETE: woo-refund-rate-analysis      ║
║  RECORDS PROCESSED: <n>                  ║
║  OUTPUT: <filename>                      ║
╚══════════════════════════════════════════╝

COMPLETION (json format):

{
  "skill": "woo-refund-rate-analysis",
  "store": "<store_url>",
  "completed_at": "<ISO-8601>",
  "records_processed": <n>,
  "output_file": "<path>",
  "dry_run": false
}

Output Format

CSV filename: woo-refund-rate-analysis_<YYYY-MM-DD>_<YYYY-MM-DD>.csv Columns: group_key, name, units_sold, units_refunded, refund_rate_pct, gross_revenue, refund_amount, net_revenue, flagged

Error Handling

Best Practices

• Investigate high-rate products for quality issues, misleading descriptions, or sizing problems.
• Use group_by: period to detect if a spike in refund rate correlates with a specific batch or promotion.
• Pair with woo-product-data-completeness-score — incomplete descriptions often correlate with high refund rates.
