Example: generate an OTP from a business flow

It is important to identify what is the business identifier that you are going to use to validate that OTP, it can be, for example, a user identification number.

1. Configure the templates that you want to use (for example, an SMS template).
2. Make sure the Kafka communication through (KAFKA_TOPIC_OTP_GENERATE_IN topic - send the otp request) and the topic used to receive the response (KAFKA_TOPIC_OTP_GENERATE_OUT) is defined properly.

3. Use the FlowX Designer to add a new Kafka send event to the correct node in the process definition.
4. Add the proper configuration to the action, the Kafka topic, and configure the body message.

5. Add a node to the process definition (for the Kafka receive event).
6. Configure on what key you want to receive the response on the process instance params.
