​
Overview

Retrieve a paginated list of customers with optional filtering and sorting. Customers are automatically created when orders are placed—you don’t need to create them separately.

​
Customer Creation

Customers are created automatically when:
  1. An order is placed with a new email address
  2. The system creates a customer record linked to that email
Subsequent orders with the same email are linked to the existing customer.

​
Common Use Cases

Customer Directory

Build customer management interfaces for your support or sales teams

CRM Integration

Sync customer data to external CRM systems like Salesforce or HubSpot

Reporting

Generate customer reports, segment customers, or analyze customer base

Support Lookup

Find customers by email or name to assist with support inquiries

​

# Get customers with active subscriptions

# Combine filters
