Key Takeaways
- RBSoft webhook depth vs an Android SMS gateway is about how each stack delivers DLR/inbound events — not a different SMS network.
- Android path: HTTPS webhooks from the control plane; verify signatures; idempotent handlers.
- Link the RBSoft hub; do not rewrite the overview.
- Accept ≠ delivered whether you poll Windows software or receive cloud webhooks.
- Live Android webhook fields live in Developer Center / product webhook docs.
- You bring the Android and operator credit. We meter devices and send volume.
Webhooks are event pipes
RBSoft SMS gateway webhook — in-depth — contrasts self-hosted Windows/modem event plumbing with Android gateway HTTPS callbacks. Hub: RBSoft alternatives. Product: SMS webhooks, DLR.
An unsigned webhook that triggers another send is how status loops become prepaid.
RBSoft-class vs Android hooks
| Concern | RBSoft-class / Windows | Android SMS gateway |
|---|---|---|
| Transport | Vendor-specific local/HTTP hooks | HTTPS callbacks from control plane |
| Auth | Per-product | Verify signatures / secrets (see docs) |
| Idempotency | Your handler | Your handler — required either way |
| Radio | Modem pool | Paired Android SIMs |
Verify before you trust
Reject unsigned payloads. Dedupe by message id. Never treat webhook loss as “resend OTP.” Live fields: Developer Center.
Cost
You bring the Android and operator SMS credit. Webhook retries that re-send SMS still meter volume. Free: 1 device / 300 SMS lifetime / 300 contacts. See device and SMS volume pricing.

- Signature verification on.
- Idempotent handlers.
