To define an API contract, specify stable endpoints, request and response payloads, and error schemas. This establishes clear data models and pagination rules, enabling frontend and backend teams to implement features concurrently with minimal ambiguity.

Idempotency in API contract design ensures that repeated requests with the same parameters produce the same result without duplicate side effects. Specifying idempotent patterns in the contract prevents ambiguity during network retries and safe client integrations.

Handle asynchronous status flows by specifying explicit asynchronous status semantics in the API contract. Define response shapes that return processing statuses, allowing frontend clients to track long-running operations without exposing internal data structures.

You need to specify API error schemas and pagination rules during the converging stage of product flows. Defining these contract elements early captures filtering patterns and error handling, preventing integration ambiguity and reducing frontend rework.

Draft a minimal v1 API contract by first outlining core user actions and backend capabilities. Then specify the required endpoints, payloads, and error handling, ensuring the contract avoids exposing internal data structures while remaining production-ready.
