What level of integration development is expected from a systems analyst — JSON contracts, error codes, idempotency, SLA?

A system analyst at the middle level is usually expected to develop integrations considering the following aspects:

• JSON Contracts: a clear description of the request and response structures, mandatory and optional fields, data types.
• Error Codes: defining a set of possible errors, their codes, and descriptions for proper handling on the client side.
• Idempotency: indicating which operations can be repeated without changing the result to avoid duplication in case of failures.
• SLA (Service Level Agreement): basic requirements for response time and service availability to align expectations between teams.

Thus, the analyst should ensure clarity and completeness of technical requirements for developers and testers so that the integration is reliable and predictable.
