Important Notice:

Payment Gateway Processor API is created by Xentaro Inc. to support Shopify payment gateway setup, API organization, and checkout readiness workflow. Payment activation depends on the selected provider, merchant eligibility, supported country, business type, Shopify settings, and provider approval.

This toolkit does not bypass Shopify checkout, provider verification, payment regulations, restricted-product rules, or merchant approval requirements. Store owners are responsible for using approved payment providers and following Shopify requirements, provider terms, customer data protection standards, and applicable payment laws.
