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 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

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 = - (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": "",
    "discount_type": "",
    "amount": "",
    "date_expires": "",
    "usage_limit": ,
    "usage_limit_per_user": ,
    "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)                       ║
║  TIME:                     ║
║  MODE:                   ║
╚══════════════════════════════════════════╝

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

[N/TOTAL]   →  records | params: =

COMPLETION (human format):

╔══════════════════════════════════════════╗
║  COMPLETE: woo-coupon-bulk-generator     ║
║  RECORDS PROCESSED:                   ║
║  OUTPUT:                       ║
╚══════════════════════════════════════════╝

COMPLETION (json format):

{
  "skill": "woo-coupon-bulk-generator",
  "store": "",
  "completed_at": "",
  "records_processed": ,
  "output_file": "",
  "dry_run": 
}

Output Format

CSV filename: woo-coupon-bulk-generator_.csv Columns: coupon_id, code, discount_type, amount, expiry_date, usage_limit, minimum_amount

Error Handling

| Error | Cause | Resolution | |-------|-------|------------| | 401 Unauthorized | Invalid credentials | Verify consumerkey and consumersecret | | 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.
