Woo Shipping Cost Analysis

woo-shipping-cost-analysis

Purpose

Analyze whether the shipping revenue collected on WooCommerce orders (via shipping_total) aligns with your shipping zone rate configuration. Identifies zones or methods where shipping is underpriced relative to actual carrier costs, and quantifies the net shipping P&L. Read-only.

Prerequisites

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

Parameters

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | store_url | string | yes | — | Base URL of the WooCommerce store | | consumer_key | string | yes | — | WooCommerce REST API consumer key (ck_...) | | consumer_secret | string | yes | — | WooCommerce REST API consumer secret (cs_...) | | dry_run | bool | no | false | No effect — read-only skill | | format | string | no | human | Output format: human or json | | date_after | string | yes | — | Start date (YYYY-MM-DD) | | date_before | string | yes | — | End date (YYYY-MM-DD) |

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 oauthconsumerkey, oauthnonce, oauthsignature, oauthsignaturemethod=HMAC-SHA1, oauthtimestamp, oauthversion=1.0

Never log or output consumerkey or consumersecret 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=T00:00:00Z&before=T23:59:59Z&per_page=100&page=1

Extract: id, shipping_total, shipping_tax, shipping_lines[].method_id, shipping_lines[].method_title, shipping_address.country

Step 2 — Fetch shipping zones and methods

GET /wp-json/wc/v3/shipping/zones

For each zone: GET /wp-json/wc/v3/shipping/zones/{id}/methods

Build map: method_id → flat_rate cost

Step 3 — Aggregate by shipping method

Group orders by shipping_lines[].method_id. For each group: total_collected = sum(shipping_total), order_count, avg_collected.

Step 4 — Export analysis

API Endpoints Used

GET  /wp-json/wc/v3/orders                       — order shipping totals
GET  /wp-json/wc/v3/shipping/zones               — shipping zone list
GET  /wp-json/wc/v3/shipping/zones/{id}/methods  — rates per zone

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)                       ║
║  TIME:                     ║
║  MODE:  READ-ONLY                        ║
╚══════════════════════════════════════════╝

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

[N/TOTAL]   →  records | params: =

COMPLETION (human format):

╔══════════════════════════════════════════╗
║  COMPLETE: woo-shipping-cost-analysis    ║
║  RECORDS PROCESSED:                   ║
║  OUTPUT:                       ║
╚══════════════════════════════════════════╝

COMPLETION (json format):

{
  "skill": "woo-shipping-cost-analysis",
  "store": "",
  "completed_at": "",
  "records_processed": ,
  "output_file": "",
  "dry_run": false
}

Output Format

CSV filename: woo-shipping-cost-analysis__.csv Columns: method_id, method_title, order_count, total_shipping_collected, avg_shipping_per_order, free_shipping_orders, configured_flat_rate

Error Handling

| Error | Cause | Resolution | |-------|-------|------------| | 401 Unauthorized | Invalid credentials | Verify consumerkey and consumersecret | | 403 Forbidden | Key lacks Read scope | Regenerate with Read scope | | 429 Too Many Requests | Rate limit | Wait 2 seconds and retry |

Best Practices

• High free_shipping_orders relative to total orders reduces average collected shipping — verify your free shipping threshold is profitable.
• Compare avg_shipping_per_order against your actual carrier invoice per shipment for the same period.
• Run quarterly to catch rate drift as carrier prices change.
