MessageFlow Priority

MessageFlow Priority is a dedicated API channel within the MessageFlow platform, designed for the prioritized handling of time-critical email and SMS messages. This service ensures maximum processing and sending priority within the MessageFlow infrastructure.

Purpose and Use Cases

The MessageFlow Priority service was developed to address the need for immediate information dispatch, where delays could lead to failed operations, user frustration, or financial losses. This particularly applies to time-sensitive messages such as:

  • One-Time Passwords (OTP / TOTP / HOTP)

  • Two-Factor Authentication (2FA) codes

  • Password reset links with limited validity

  • Critical security alerts requiring immediate action

  • Instant payment and transaction confirmations

Standard channels may experience delays due to message queuing, anti-spam filters, throttling by recipient servers, and limited control over processing times by external operators. MessageFlow Priority minimizes risks within the MessageFlow sending layer.

Technical Features

MessageFlow Priority provides a dedicated, fast path within the MessageFlow infrastructure, characterized by:

  • Maximum technical priority: Messages are processed first, bypassing standard queues.

  • Dedicated infrastructure: The solution is resilient to overloads and scalable to handle peak traffic.

  • Advanced security: Includes encryption, authorization, and compliance with industry best practices.

  • Minimization of internal risk: Eliminates internal bottlenecks within MessageFlow to ensure the fastest possible message dispatch.

Note: The final delivery time of messages to the end recipient still depends on recipient servers and providers (e.g., GSM operators, mailbox providers) and is beyond MessageFlow's control.

Glossary

  • 2FA (Two-Factor Authentication): A security method requiring two distinct factors to verify user identity.

  • OTP (One-Time Password): A code used only once for user authentication, often in banking and login processes.

  • TOTP (Time-based One-Time Password): A password valid for a specific duration (e.g., 30 seconds), dynamically generated based on a system clock.

  • HOTP (HMAC-based One-Time Password): A one-time password generated based on a counter, valid until used.
