Creates a new customer object in Zenskar. Customer objects represent the individuals or companies you do business with and serve for your revenue operations—they must exist before you can create contracts, generate invoices, or process payments.

The customer record stores essential billing information including contact details, billing and shipping addresses, tax identifiers, payment preferences, and custom metadata specific to your business needs. Only customer_name is required at creation—all other fields are optional, allowing you to capture minimal information initially. The customer address is an important field which is used for Regional tax calculation, make sure this field is correct for the required customers.

When integrated with external systems, newly created customers are automatically synchronized with configured platforms like Stripe, HubSpot, Zoho, or Xero. Use the external_id field to maintain references to source systems for bidirectional synchronization.
