Summary
Direct integration family
Billie’s official documentation describes integrating its B2B payment methods into merchant checkout and back-office operations. The reviewed material is maintained as living technical documentation.
Checkout components
The integration distinguishes front-end and back-end order creation and the authentication needed for the documented calls. These components coordinate the customer interaction with the merchant’s payment request.
Order lifecycle
The reference covers order management, captures and refunds. Those operations follow the created order through subsequent merchant actions rather than treating checkout creation as the entire payment lifecycle.
Implementation checklist
Billie’s checklist connects the required integration calls. The reviewed pages do not identify a stable dated edition, so the family entry should not be assigned a universal release or treated as an open multi-provider payment standard.
