Naming Guidelines for Custom Checkout Fields
When adding custom fields in Checkout Manager, always include a prefix to ensure proper integration with the checkout system. Use one of the following as a prefix depending on the type of field:
- billing_ for billing information (e.g., billing_tax_number)
- shipping_ for shipping information (e.g., shipping_instructions)
- additional_ for any extra fields (e.g., additional_notes)
