# Customers

Customers are the people who create orders. A customer object must have an email and channel. All necessary information about customers is kept in customer objects. This includes information about communication permissions accepted by customers for example: email\_allowed, sms\_allowed etc.

## Customer Creation

In order to create a customer record on the Omnitron product, any order from the marketplace must be fetched to Omnitron. When the relevant command runs in marketplace integrations, the order is created in Omnitron. At this stage, if the customer record has not been created before, customer information is created; if the customer record has been created before, the customer information is updated (works with the Upsert logic). Service methods are used in these creation and update processes.

In the integration document, the creation of the order and, accordingly, the creation of the customer will be discussed.
