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.
Important information: MessageFlow Priority is an add-on service, and its availability and fees may depend on your selected plan.
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.

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.
