In this exercise we will use the RESTful APIs in order to create and update a resource and

consume the resulting event from the relevant Kafka topic.

Core Streaming API: Customers

There are three different events that are generated when a customer entity is created or

updated in the Vault Core system. These are:

● CustomerCreatedEvent

○ vault.api.v1.customers.customer.created

○ Generated when a customer is created

● CustomerDetailsUpdated

○ vault.api.v1.customers.customer.customer_details.updated

○ Generated when a customer’s details are updated

● CustomerAddressEvent

○ vault.core_api.v1.customers.customer_address.events

○ Generated when a customer address event is published
