1. From Notification Service **Sync AP**I call is sent to the **SMS/email** provider and **Async API** call is sent to the **Kafka cluster**.
2. If processing the notification is failed then the same message is pushed to the topic **Kafka** and then it is processed by the notification flink job in Lern data-pipeline.
