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.
