Key Takeaways
- Shopify ↔ Android SMS Gateway is HTTP glue: Shopify webhooks (or Flow HTTP) hit your bridge; the bridge POSTs to REST send.
- Not a closed Shopify App Store requirement from us — HTTPS JSON is enough.
- Verify Shopify signatures and gateway webhook signatures separately.
- You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. Service pricing is based on device count and total SMS sent through the gateway.
- Free canaries: 300 SMS lifetime — not Unlimited SMS.

The webhook pattern
Shopify pushes JSON to your HTTPS URL. You normalize the phone, build the SMS body, call the gateway with Bearer + Idempotency-Key (order id works). Confirm live send fields in SMS API documentation.
If Shopify never delivered the webhook, the phone is innocent. Fix the store topic before OEM battery pages.
Shopify → bridge → Android
Pair the handset via setup. Keep OTP (if any) off campaign order blasts.
Event mapping
| Shopify topic (example) | SMS purpose | Watch-outs |
|---|---|---|
| orders/create | Order received | Consent; quiet hours for promo copy |
| fulfillments/create | Shipped | Tracking URL length / Unicode |
| customers/update | Rarely SMS | Noise; prefer explicit events |
| refunds/create | Refund notice | PII minimization in body |
Two HMACs
Shopify webhook secret ≠ gateway webhook secret. Verify both when you also consume DLR callbacks.
Ops pitfalls
At-least-once Shopify delivery → duplicates without Idempotency-Key. Offline phones queue. Airtime still yours. DLR: delivery reports.
Next steps
Canary one order webhook end-to-end, then enable production topics.
