Key Takeaways
- Scenario 1393 is try-before-you-buy / home try-on kit webhooks — not subscription skips, BOPIS stalls, waitlist restocks, preorder drops, gift cards, COD, split-ship, refunds, or renewals.
- “Kit K-771 is out — keep by Sunday” is transactional. “Try more frames” is marketing. Split SIMs.
- Cap SMS per kit id. WMS retries of kit.shipped will empty prepaid.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300. Developer is 25,000 SMS per year.
- Verify HMAC. A forged kit.due event nags people who already returned the box.
- REST fields live in Developer Center — not a CodeCanyon try-on plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 1393 is ecommerce webhooks for home try-on kits. The kit system owns the box. Your worker texts shipped / due / received — not the whole “try more” segment. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If you key SMS on SKU instead of kit+state, the second warehouse ping will re-announce a box that already came back.
