Key Takeaways

  • Scenario 853 is loyalty-points expiry webhooks — not gift-wrap ready, digital downloads, pre-auth holds, custom-proof approval, line-item cancels, warranty, store credit, price-match, try-on kits, subscription skips, BOPIS, waitlist restocks, preorder drops, gift-card sales, COD, split-ship, refunds, or renewals.
  • “Points cohort C-60 expire in 7 days” is transactional. “Shop the sale again” is marketing. Split SIMs.
  • Cap SMS per cohort id. Loyalty-engine retries of points.expiring 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 points.expiring event nags people whose balance already rolled.
  • REST fields live in Developer Center — not a CodeCanyon loyalty plugin. MCP, if you use it, is only a REST wrapper.

Summary

Scenario 853 is ecommerce webhooks for loyalty-points expiry. The loyalty engine owns the cohort. Your worker texts expiring / expired — not the whole “shop the sale again” segment. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.

If you key SMS on member id instead of cohort+date, the second engine ping will re-open a 7-day clock that already rolled.
