# ADR 003: Dispatch SMS Through RabbitMQ

## Status

Accepted.

## Context

SMS providers are external services and can fail or respond slowly.

## Decision

Publish OTP SMS jobs to RabbitMQ and process them in a dedicated worker with manual acknowledgements, retries, and a dead-letter queue.

## Consequences

The auth service remains responsive. SMS delivery is isolated and easier to retry, monitor, and replace.
