# What are Customer Segments on Vouchery?

At Vouchery, customer segments refer to groups of customers who share similar characteristics or behavior patterns. To create these segments, specific criteria such as purchase history, order value, geographic location, and browsing behavior are used.

Properly defining and managing customer segments is crucial in tailoring marketing and promotion strategies. Personalized promotions targeted towards specific customer segments can enhance customer engagement and retention, and ultimately improve sales performance.

# How does Vouchery validate Customer Segment restrictions?

Our system verifies Customer Segment restrictions set in the promotion against the internal Customer Segment data when a particular customer uses a promotional code. In order to do this, we need the Customer ID to be included in the API requests, during the validation or the redemption process.

Here is an example request for redemption:

Adding Customer ID for coupon redemption API request on Vouchery.io


Manual redemption

When redeeming a voucher, a Customer ID must be added for validation when Customer-related restrictions are set for the campaign.

When the redemption is done through our mobile QR code scanner, we won't be able to validate the Customer Segment restrictions.
