Key Takeaways
- Scenario 1163 is vehicle classifieds hold-until-cash lists — not lost-found lockers, charity vans, will-call, consignment, booth maps, wholesale pallets, RMA bays, meetup pins, escrow vaults, age-gates, or seller KYC.
- “Lot C-4, VIN last-4 8821, cash window 10:00” is transactional. “More cars this week” is marketing. Split SIMs.
- Free caps contacts at 300. Do not keep every expired hold in the gateway book.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Developer is 25,000 SMS per year.
- Staff console OTP stays on its own phone. A Saturday lot will starve it if shared.
- REST list/send fields live in Developer Center — not a CodeCanyon auto plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 1163 is marketplace contact lists for vehicle hold-until-cash windows. The lot system owns the VIN last-4. The Android texts the buyer a stall and a clock. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If you reuse last week’s “open holds” dump, you will text people whose car already left — and they will treat CASH as spam.
