Does fraud.review SMS include carrier credit?

No. Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The risk SIM still needs operator balance.

Can payment.capture share the review handler?

No. Split HMAC routes so a capture wave cannot starve review texts.

Should checkout OTP use the review SIM?

No. Isolate OTP so a review spike cannot starve login codes.

Android SMS Gateway Scenario 1057: Ecommerce webhooks in practice

Key Takeaways

fraud.review texts the risk desk; payment.capture texts the card desk — never the same HMAC handler.
A capture blast on the review SIM will starve “hold for review” texts at the risk bench.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime; Developer is 25,000 SMS per year.
This is our signed webhook path, not a CodeCanyon shop plugin. MCP only wraps REST if you add it.
Checkout OTP stays off both review and capture radios.
Developer Center owns live webhook fields.

Summary

A fraud hold is not a capture. Risk texts fire on fraud.review; card texts fire on payment.capture. Split HMAC handlers so a capture wave cannot starve “hold for review.” Priced by devices and SMS send volume. You use your own phone and operator SMS credit.

If fraud.review and payment.capture share one handler, the risk desk loses when finance fires.

Fraud review vs capture HMAC

Event	SIM	Never
fraud.review	Risk desk	Capture copy, OTP
payment.capture	Card / finance	Review-hold copy
Checkout OTP	Isolated radio	Either HMAC lane

Key takeaways

Split HMAC routes for review vs capture.
Risk texts stay off the finance SIM.
Checkout OTP stays off both.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
Not a CodeCanyon shop plugin. MCP wraps REST if you add it.
Canary both events on staff orders before peak review days.

Context

Risk desks use this ecommerce scenario to pin review holds to fraud.review and card texts to payment.capture.

Radio reality still wins: offline phones and OEM killers break scenarios overnight.

Cross-link hub cornerstones instead of rewriting the product overview.

Keep examples conceptual until Developer Center confirms live request shapes.

Budget airtime for retries — failed loops still cost operator credit.

Core scenario guidance

Map fraud.review, payment.capture, and checkout-OTP moments to separate HMAC handlers before peak review days.

Separate configuration mistakes from radio failures during incidents.

Write acceptance criteria before seasonal or clinic-hour traffic.

Prefer gradual rollout with feature flags when automation is involved.

Cost and ownership

Model review days as devices plus volume plus airtime on signed events only. Free is 300 lifetime SMS; Developer is 25,000 SMS per year.

Failed retries still burn credit during scenario experiments.

Assign who owns SIM top-ups and spare handsets.

Keep marketing spend out of OTP device pools.

Operations

Daily checks: pairing health, battery, queue depth, and DLR anomalies.

After OEM updates or SIM swaps, re-test the scenario path end to end.

Keep a spare charged device ready for failover drills.

Name an on-call owner before unattended sends go live.

Security and compliance

Protect API keys per environment; rotate after contractor access ends.

STOP and consent still apply on promotional scenario lanes.

Avoid logging full OTP bodies into shared chat.

Verify webhook signatures and TLS on every callback path.

Decision guide

Ship review vs capture HMAC only when signature checks, slot owners, and OTP isolation are written.

Delay if you cannot explain offline-phone behavior during peak hours.

If zero phone ops is mandatory, evaluate CPaaS for that lane.

If local SIM economics matter, harden the Android path and monitor airtime.

Deep dive: production hardening

Multi-device failover only helps if spare phones stay charged and paired.

MMS attachments inherit carrier size and APN limits.

USSD requests are carrier- and region-sensitive; treat timeouts as expected.

Contact lists need consent metadata stored with the number.

OTP priority queues fail when marketing blasts share the same device pool.

Spare charged devices matter more than brochure SLAs when phones send the SMS.

Airtime surprise bills happen when bulk loops ignore radio pace.

OTP and marketing must stay on separate lanes on every scenario.

Never claim unlimited free cloud SMS credits with no device or volume meter.

Name an on-call owner before unattended schedules go live.

Canary on staff numbers before customer OTP.

Battery exemptions and OEM killers dominate overnight reliability.

Cross-link Setup, Pricing, Downloads, and Developer Center with keyword-rich anchors.

If zero phone ops is mandatory, evaluate CPaaS for that lane instead.

Webhook signature verification is non-negotiable for scenario automation.

Document who owns SIM top-ups for multi-site scenario rollouts.

Prefer honest latency expectations over marketing claims about global SLAs on SIM paths.

Scenario playbooks still bill by devices and SMS send volume. You bring the Android phone and operator SMS credit.

Developer Center owns live API parameters. Scenario blogs teach process and failure modes, not endpoint catalogs.

Ecommerce webhooks must verify signatures before they trigger SMS sends.

Clinic reminders need consent records and STOP handling even when messages feel transactional.

Logistics ETAs should degrade gracefully when devices go offline mid-route.

Edtech OTP spikes at exam windows — capacity plan devices before the semester starts.

Fintech OTP is high-stakes: isolate devices, rotate keys, and avoid logging full codes.

Real-estate nurture is promotional; keep it off OTP SIMs and honor quiet hours.

Restaurant reservation SMS still needs STOP on marketing lanes.

SaaS onboarding OTPs should canary on staff numbers before paid scale.

Field-service dispatch needs two-way inbox ownership so techs are not double-booked.

Marketplace seller alerts need multi-device failover when a single phone is the SPOF.

NGO outreach must separate fundraising blasts from operational alerts.

Appointment businesses live on reminder deliverability the morning of the visit.

Bulk CSV import needs validation before radio send; bad rows burn airtime.

Scheduled SMS must survive device sleep and timezone mistakes.

Auto-reply and STOP protect promotional lanes — never auto-reply into OTP threads.

Dual SIM routing fails when slot maps drift after reboot without re-pair.
