Standardize Authentication Response Format

[DevMuhdishaq]

Overview

Create and enforce a standardized response format for all authentication-related endpoints to improve API consistency and client integration.

Objectives

• Define standard authentication response schema
• Define standard error response schema for auth failures
• Standardize HTTP status codes for auth operations
• Document all authentication response formats
• Ensure consistency across all auth endpoints

Implementation Details

• Create response DTO/schema for login, logout, token refresh
• Include metadata in responses (token type, expiration)
• Standardize error messages and codes
• Add validation for response format consistency
• Create comprehensive API documentation

Response Format Example

{
  "status": "success",
  "data": {
    "accessToken": "eyJhbGc...",
    "refreshToken": "eyJhbGc...",
    "tokenType": "Bearer",
    "expiresIn": 3600,
    "user": { "id": "123", "email": "user@example.com" }
  }
}

Acceptance Criteria

• All auth endpoints follow standardized response format
• Error responses include proper status codes and messages
• Response documentation is complete
• API clients can reliably parse auth responses
