# Business flow example

> We will explore an example in which we integrate a customer search in a business flow.

Follow the next steps to use the user personal number to perform a search query in the customer management plugin.

1. First make sure the details about customers are indexed in the search engine (for example, elasticSearch).
2. Open **FlowX Designer** and create a **process definition**.
3. Add a [**Send Message Task**](../../../../building-blocks/node/message-send-received-task-node#message-send-task) node.
4. Configure the [**Send Message Task**](../../../../building-blocks/node/message-send-received-task-node#message-send-task) node by adding the following elements:

* Kafka topic - defined on the `KAFKA_TOPIC_CUSTOMER_SEARCH_IN` environment variable
* Message body (example of identifiers for an indexed customers):

  For more examples of keys, check [**Using the customer management plugin**](./customer-management-overview#key-examples).
</Check>

5. Add a [**Receive Message Task**](../../../../building-blocks/node/message-send-received-task-node#message-receive-task).
6. Configure the topic on which you want to receive the response from the CRM, on the value of `KAFKA_TOPIC_CUSTOMER_SEARCH_OUT` environment variable.
