Key Takeaways

  • Scenario 1633 is preorder / drop-release webhooks — not gift cards, split-ship, COD, refunds, renewals, or first paid/shipped.
  • “Your preorder is allocating” is transactional. “More drops this week” is marketing. Split SIMs.
  • Cap SMS per buyer per wave. A bot farm of webhooks will empty prepaid and get the SIM filtered.
  • 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. Forged inventory.release events lie about stock and burn airtime.
  • REST fields live in Developer Center — not a CodeCanyon drop plugin we resell.

Summary

Scenario 1633 is ecommerce webhooks for preorder and drop release. The storefront emits an allocation event. Your worker authenticates it, then texts the buyers who actually have a unit — not the whole waitlist twice. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.

If you key SMS on SKU instead of release+buyer, the second warehouse ping will re-announce a drop that already sold out.
