How should the level of detail and focus in client-facing documentation differ when explaining OTP API design rationale to a solution architect compared to providing implementation specifics for a backend developer?

The level of detail and focus in client-facing documentation for an OTP API must fundamentally differ based on the audience, specifically a solution architect versus a backend developer, due to their distinct roles and responsibilities within a project. For a solution architect, the documentation should focus on the design rationale of the OTP API, which refers to the underlying reasoning, principles, and trade-offs that led to specific architectural and functional choices. This level of detail is high-level and conceptual, explaining *whycertain decisions were made and their impact on the broader system. A solution architect needs to understand the architectural implications, scalability considerations, and security posture of the OTP API within the entire enterprise ecosystem. For instance, the documentation should explain the choice of using a stateless API for OTP generation and verification to ensure horizontal scalability, detailing how the server does not store session information between requests. It should cover the rationale behind specific rate-limiting strategies implemented at the API gateway level to prevent brute-force attacks, explaining the security benefits and potential ....
