Woo coupon bulk generator

woo-coupon-bulk-generator

Purpose

Generate a batch of unique WooCommerce coupon codes with configurable discount type (percentage or fixed cart), amount, expiry date, usage limit, and minimum order amount. Exports the generated codes as a CSV for distribution in email campaigns or loyalty programs.

Prerequisites

• WooCommerce store with REST API enabled
• Consumer Key with Read/Write 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	true	Preview generated codes without creating them
format	string	no	human	Output format: human or json
count	int	yes	—	Number of unique coupon codes to generate
discount_type	string	no	percent	percent, fixed_cart, or fixed_product
amount	number	yes	—	Discount value (percent as 0–100, fixed as currency amount)
expiry_date	string	no	—	Expiry date in YYYY-MM-DD format
usage_limit	int	no	1	Times each coupon can be used total
usage_limit_per_user	int	no	1	Times each coupon can be used per customer
minimum_amount	number	no	—	Minimum order amount for coupon to apply
code_prefix	string	no	PROMO	Prefix for generated codes (e.g., SPRING25-XXXXXXXX)
code_length	int	no	8	Random suffix character length

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 2 creates live coupon codes in WooCommerce. Always run with dry_run: true first to preview the code format, amount, and count before creating. Creating coupons cannot be undone in bulk — they must be deleted individually.

Workflow Steps

Step 1 — Generate unique codes

For each of count iterations:

• Generate a random alphanumeric suffix of code_length characters
• Code = <code_prefix>-<suffix> (uppercased)
• Ensure no duplicates within the batch (regenerate if collision)

Step 2 — Preview or create

If dry_run: true: display first 10 codes and config. Stop.

If dry_run: false and confirmed:

For each code:

POST /wp-json/wc/v3/coupons
  Body: {
    "code": "<code>",
    "discount_type": "<discount_type>",
    "amount": "<amount>",
    "date_expires": "<expiry_date>",
    "usage_limit": <usage_limit>,
    "usage_limit_per_user": <usage_limit_per_user>,
    "minimum_amount": "<minimum_amount>"
  }

Emit progress every 25 coupons.

API Endpoints Used

POST  /wp-json/wc/v3/coupons   — create individual coupon codes

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-coupon-bulk-generator        ║
║  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-coupon-bulk-generator     ║
║  RECORDS PROCESSED: <n>                  ║
║  OUTPUT: <filename>                      ║
╚══════════════════════════════════════════╝

COMPLETION (json format):

{
  "skill": "woo-coupon-bulk-generator",
  "store": "<store_url>",
  "completed_at": "<ISO-8601>",
  "records_processed": <n>,
  "output_file": "<path>",
  "dry_run": <bool>
}

Output Format

CSV filename: woo-coupon-bulk-generator_<YYYY-MM-DD>.csv Columns: coupon_id, code, discount_type, amount, expiry_date, usage_limit, minimum_amount

Error Handling

Error	Cause	Resolution
401 Unauthorized	Invalid credentials	Verify consumer_key and consumer_secret
403 Forbidden	Key lacks Read/Write scope	Regenerate with Read/Write scope
woocommerce_rest_coupon_code_already_exists	Code collision with existing coupon	Increase code_length or change code_prefix
429 Too Many Requests	Rate limit during creation	Wait 2 seconds and retry

Best Practices

• Always run with dry_run: true first to confirm code format before creating.
• Use a meaningful code_prefix that identifies the campaign (e.g., SPRING25, VIP).
• Set expiry_date to avoid codes being used after the campaign ends.
• Import the CSV directly into your email platform to assign one code per recipient.
