        "content": "# Send WooCommerce Discount Coupons to Customers via WhatsApp Using Rapiwa API\n\n## Overview\nThis workflow listens for WooCommerce coupon creation events (coupon.created) and uses customer billing data to send promotional WhatsApp messages via the Rapiwa API. The flow formats the coupon data, cleans phone numbers, verifies WhatsApp registration with Rapiwa, sends the promotional message when verified, and logs each attempt to Google Sheets (separate sheets for verified/sent and unverified/not sent).\n\n## Features\n- Trigger: fires on WooCommerce coupon creation (`coupon.created`) using the `WooCommerce Trigger` node.\n- Coupon formatting: `Format WooCommerce Trigger Response Data` code node normalizes coupon fields into `data.coupons` (couponCode, discountAmount, discountType, description, dateCreate, dateExpires, freeShipping).\n- Phone cleaning: `Clean WhatsApp Number` ensures phone numbers contain only digits (String(rawNumber).replace(/\\D/g, \"\")).\n- Pre-send verification: calls Rapiwa verify endpoint (POST https://app.rapiwa.com/api/verify-whatsapp) to confirm WhatsApp registration.\n- Message sending: POST to https://app.rapiwa.com/api/send-message with a templated promo message built from coupon fields.\n- Audit logging: appends rows to Google Sheets for both verified/sent and unverified/not sent results.\n\n## Requirements\n- Rapiwa account and a valid Bearer token (used by the HTTP Request nodes).\n- Google account with Sheets access and an OAuth2 credential for the Google Sheets nodes.\n- WooCommerce store configured to emit coupon.created events (or use a webhook equivalent).\n\n\n## Google Sheet Required Columns\n**A Google Sheet formatted like this** \u27a4 [sample](https://docs.google.com/spreadsheets/d/14UclmcZ7TGU4Qaag89yaZLVFee1IQNA6t-uhgN8_TAE/edit?usp=sharing)\n\n\n## Nodes Used in the Workflow\n- `WooCommerce Trigger` \u2014 listens for `coupon.created` events. Example webhookId present in the export.\n- `Format WooCommerce Trigger Response Data` (Code) \u2014 maps incoming coupon fields to a `data.coupons` array. \n- `Check valid whatsapp number Using Rapiwa` (HTTP Request) \u2014 POST https://app.rapiwa.com/api/verify-whatsapp with body { number: ={{ $json.billing.phone }} } and HTTP Bearer auth.\n- `Send Message Using Rapiwa` (HTTP Request) \u2014 POST https://app.rapiwa.com/api/send-message with body fields: number, message_type=text, message (templated using coupon data). Example message in flow uses `Format WooCommerce Trigger Response Data` coupon fields.\n- `Save State of Rows in Verified & Sent` / `Save State of Rows in Unerified & Not sent` (Google Sheets) \u2014 append rows with mapped coupon/customer fields.\n\n## How to Use This Workflow\n1) Configure credentials in n8n\n   - Create `Rapiwa Bearer Auth` (HTTP Bearer) and paste your token.\n   - Add `Google Sheets` OAuth2 credentials.\n   - Add WooCommerce API credentials (example name in flow: `WooCommerce (get customer)`).\n\n2) Create or update Google Sheets\n   - Create sheets with headers matching the keys listed in \"Google Sheet Required Columns\".\n   - Replace the example spreadsheet IDs in the Google Sheets nodes with your own spreadsheet ID and sheet gid.\n\n4) Validate Code nodes\n   - Check `Format WooCommerce Trigger Response Data` to ensure coupon fields exist in your WooCommerce payload.\n   - Confirm `Clean WhatsApp Number` is using the same field name where the phone lives (billing.phone or another path).\n\n5) Check HTTP Request nodes\n   - Ensure `Check valid whatsapp number Using Rapiwa` uses the correct number expression and the `Rapiwa Bearer Auth` credential.\n   - Review the `Send Message Using Rapiwa` templated message to ensure it references the correct coupon/customer fields.\n\n\n## Notes & Warnings\n- The Google Sheets mapping in the flow contains a field named `aouponAmount` (typo). If you want `couponAmount` in your sheet, either rename the mapping or rename the sheet header.\n- The `If` node logic and the Rapiwa responses should be tested \u2014 the exported IF compares to a string in other exports; normalize boolean/string types before comparison.\n- Do not hard-code credentials or tokens in nodes; use n8n credentials.\n- Ensure the phone field used by `Check valid whatsapp number Using Rapiwa` matches the cleaned number path used by `Clean WhatsApp Number`.\n- Test with a small number of coupons first to confirm message content and rate-limiting behavior.\n\n\n## Useful Links\n- **Dashboard:** [https://app.rapiwa.com](https://app.rapiwa.com/login)\n- **Official Website:** [https://rapiwa.com](https://rapiwa.com/)\n- **Documentation:** [https://docs.rapiwa.com](https://docs.rapiwa.com/)\n\n## Support & Help\n- **WhatsApp**: [Chat on WhatsApp](https://wa.me/8801322827799)\n- **Discord**: [SpaGreen Community](https://discord.gg/SsCChWEP)\n- **Facebook Group**: [SpaGreen Support](https://www.facebook.com/groups/spagreenbd)\n- **Website**: [https://spagreen.net](https://spagreen.net)\n- **Developer Portfolio**: [Codecanyon SpaGreen](https://codecanyon.net/user/spagreen/portfolio)\n"
