Key Takeaways
- A “slot open, floor 12 canteen” text is operational. A “join the smoothie perks club” blast is promo with STOP.
- HELP must name the floor they booked — not the whole campus HQ.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Auto-reply never invents a diet clearance or a meal-credit refund.
- SSO / badge OTP stays off the canteen radio.
Summary
Scenario 811 is auto-reply and STOP for office-HQ canteen lunch slots — not hospital staff trays, not campus dining halls, not bakeries, not lounges. The employee booked a 12:20 window on floor 12. Perks and smoothie-club copy must not share that radio or that suppress list. Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: canteen dual-SIM plus a spare. Uncapped platform volume is not unlimited carrier SMS. Confirm keywords in Developer Center.
floor · slot · STOP perks
booking-id + day — never a diet pass
A lunch-slot text is not a perks blast
Ready copy names the floor and window. Perks clubs live on a different purpose and a different STOP. Mixing them means someone who hates merch also misses the only slot they booked between meetings.
Auto-reply and STOP, transactional SMS.
If HELP answers with the HQ gym URL instead of “Floor 12, 12:20,” the employee walks to the wrong tower. Operational HELP stays local to the ticket.
Canteen STOP matrix
| Message | Purpose | Failure |
|---|---|---|
| Slot open / ready | In-flight booking | Perks STOP mutes the floor |
| Smoothie / perks | Promo + STOP | Same SIM as slots |
| HELP | Floor + window | All-HQ dump |
| Badge OTP | Auth pool | OTP on the canteen radio |
Floor vs all-HQ promo
Persist booking-id plus day. Signed webhooks. Webhooks, DLR. MCP wraps REST only.
Diet replies are not auto
Auto-reply never grants a diet clearance or a meal-credit refund. Staff handle that. CDC nutrition is not an SMS decision.
Devices, volume, and airtime
Noon banks spike. We meter devices and platform sends. Free (1/300/300) is one floor proof.
Workplace-dining operations
Charge the canteen chassis before 11:30. Setup, Downloads, pricing.
Decision guide
Ship when promo STOP is purpose-level. Delay if one SIM does slots and perks. Not a CodeCanyon canteen pack.
