One-time code (OTP) and two-factor verification API
An OTP is a one-time code sent to the user for login, registration, password reset or approval, typically through SMS, email or an automated voice call.
Overview
- One-time code (OTP) creation and verification
- Expiry handling
- Resend limits
- Attempt limits
- Rate limiting
What is this solution?
OTP stands for One-Time Password, often used as a one-time verification code. The BitMessaging Verify API manages the complete workflow: code generation, delivery, expiry, resend, attempt limits, verification and reporting.
How it fits into the platform
Your system requests a code from BitMessaging, the platform delivers it to the user through the right channel, and then verifies through API whether the user entered the same one-time code.
What problem does it solve?
Building a one-time-code verification process in-house often becomes technical debt. Weak limit handling, unreliable fallback or poor error handling lowers user success rates and increases risk.
One communication layer instead of separate tools
The solution connects business events, routing, fallback and reporting into one workflow, so customer communication becomes easier to operate and audit.
How does it work?
Event
Your business system creates an event with the recipient, message text and the required context.
Routing
BitMessaging receives the request, validates access and selects the configured channel or sending method.
Fallback
If needed, the workflow can switch to another channel and continue with retry or fallback rules.
Report
Message ID, delivery status, callback data and reports close the workflow for your team.
