Delivery Agency API Integration and Failure Response - Oneul Dream Service Development Story
Key point
This introduces the delivery agency API integration method and failure response strategy for the stable operation of Olive Young's Oneul Dream service.
Details
Olive Young's instant delivery service, Oneul Dream, operates through close API integration with external delivery agencies. The integration consists of two stages: an 'order receipt API' through which Olive Young requests delivery, and a 'callback API' through which the delivery agency updates delivery status.
Temporary errors that can occur during order receipt, such as Read Timeout or Connection Timeout, are handled internally through retries. In particular, to prevent duplicate order issues that can occur when a Timeout happens, the delivery agency's duplicate receipt response (409 Conflict) feature is utilized to maintain data consistency.
Additionally, to solve the problem of increasing management points as the number of delivery agencies grows, a callback API renewal was carried out. APIs that had been fragmented across each agency were unified into one, preventing omissions that could occur when modifying features and improving maintenance efficiency.
