woo-customer-note-bulk-annotator

Purpose

Append a text note to the WooCommerce customer note field (customer_note) for multiple customers matching a filter (role, spend range, country, or registration date). Useful for adding internal flags, account status notes, or support context in bulk. Includes dry-run preview.

Prerequisites

• WooCommerce store with REST API enabled
• Consumer Key with Read/Write 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

Step 3 writes to customer records. Always run with dry_run: true first (the default). If append_mode: false, existing customer notes are overwritten.

Workflow Steps

Step 1 — Fetch filtered customers

GET /wp-json/wc/v3/customers?per_page=100&page=1
  [&role=<filter_role>]
  [&country=<filter_country>]

Filter client-side by total_spent range. Extract: id, email, customer_note

Step 2 — Compute new note

If append_mode: true: new_note = existing_note + "\n" + note + " [" + date + "]" If append_mode: false: new_note = note

Step 3 — Preview or execute

If dry_run: true: list customers. Stop.

If dry_run: false and confirmed:

PUT /wp-json/wc/v3/customers/{id}
  Body: { "customer_note": "<new_note>" }

API Endpoints Used

GET  /wp-json/wc/v3/customers        — filtered customer list
PUT  /wp-json/wc/v3/customers/{id}   — write updated note

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-customer-note-bulk-annotator ║
║  STORE: <store_url>                      ║
║  TIME:  <ISO-8601 UTC>                   ║
║  MODE:  <DRY RUN | LIVE>                 ║
╚══════════════════════════════════════════╝

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

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

COMPLETION (human format):

╔══════════════════════════════════════════╗
║  COMPLETE: woo-customer-note-bulk-anno.  ║
║  RECORDS PROCESSED: <n>                  ║
║  OUTPUT: stdout                          ║
╚══════════════════════════════════════════╝

COMPLETION (json format):

{
  "skill": "woo-customer-note-bulk-annotator",
  "store": "<store_url>",
  "completed_at": "<ISO-8601>",
  "records_processed": <n>,
  "output_file": null,
  "dry_run": <bool>
}

Output Format

Human format: count of customers to annotate and the first 10 email addresses.

Error Handling

Best Practices

• Always run with dry_run: true first.
• Use append_mode: true (the default) to preserve existing notes.
• Include the date in your note text for a built-in audit trail.
