Order Cart Adjustment V2
WHAT
DoorDash is enhancing its Order Cart Adjustment (OCA) feature to simplify how order changes are handled between merchants, customers, and providers. The upgraded experience introduces better transparency for customers, easier adjustments for merchants, and improved data consistency for providers—reducing friction and creating a smoother live order experience.
WHY
In the current OCA flow, customers are unable to review or accept order changes made by merchants, and providers lack a simple way to retrieve the fully updated order payload once adjustments are applied. These limitations can create reconciliation challenges on POS systems, add technical and operational overhead, and lead to suboptimal customer and merchant experiences.
By rebuilding OCA (OCA 2.0), we aim to close these usability and technical gaps through an improved API and notification flow that enables:
- Customer transparency and control, allowing them to accept or reject adjustments;
- Seamless merchant experience, enabling adjustments directly from POS without support calls;
- Accurate provider reconciliation, through a webhook and GET endpoint for updated order payloads;
- Reduces order cancellations and improves the overall live order experience.
