CASE ANALYSIS

Scenario

Illustrates the request journey for a social media post creation API endpoint from input parsing to response, including validation, authentication, rate limiting, database persistence, and notification.

Key decisions

  • Validate input and return 422 on invalid payload
  • Check authentication and return 401 if missing or invalid
  • Enforce rate limiting and return 429 when exceeded
  • Commit post to database and return 201 with ID or 500 on failure

When to reuse this

Reuse when designing or documenting REST API endpoints that create user-generated content and require validation, rate limiting, and persistence error handling.
