# Error Response Format Standardization
## INT-006: Standardize error response format
**Date**: 2025-12-25
**Status**: Completed
## Summary
All error responses in the Veza API now use a consistent, standardized format that matches the `APIResponse` envelope structure.
## Standard Error Response Format
All error responses follow this structure:
```json
{
"success": false,
"data": null,
"error": {
"code": 1000,
"message": "Error message",
"details": [
{
"field": "email",
"message": "Invalid email format"
}
],
"request_id": "550e8400-e29b-41d4-a716-446655440000",
"timestamp": "2025-12-25T10:30:00Z",
"context": {
"user_id": "123e4567-e89b-12d3-a456-426614174000"
}
}
}
```
### Error Object Fields
- **code** (number, required): Error code from the error code system (1000-9999)
- **message** (string, required): Human-readable error message
- **details** (array, optional): Array of validation error details
- **field** (string): Field name that failed validation
- **message** (string): Field-specific error message
- **value** (string, optional): Invalid value that was provided
- **request_id** (string, optional): Request ID for tracking and debugging
- **timestamp** (string, required): ISO 8601 timestamp of when the error occurred
- **context** (object, optional): Additional context information (user_id, etc.)
## Implementation
### Backend
All error responses are now standardized through:
1. **`RespondWithAppError`** (`internal/handlers/error_response.go`):
- Primary function for sending standardized error responses
- Uses `AppError` type from `internal/errors`
- Automatically includes request_id, timestamp, and context
2. **Error Handler Middleware** (`internal/middleware/error_handler.go`):
- Catches all unhandled errors
- Converts them to standardized format
- Uses `APIResponse` envelope structure
3. **Handler Functions**:
- All handlers use `RespondWithAppError` for errors
- No direct `gin.H{"error": ...}` usage
- Consistent error handling across all endpoints
### Frontend
The frontend already handles the standardized format through:
1. **`parseApiError`** (`apps/web/src/utils/apiErrorHandler.ts`):
- Parses backend error responses
- Handles multiple response formats (legacy and new)
- Normalizes to `ApiError` type
2. **`ApiError` Type** (`apps/web/src/types/api.ts`):
- Matches backend error structure
- Includes all standard fields
3. **Error Handling**:
- Axios interceptors handle error responses
- User-friendly error messages displayed
- Request ID available for debugging
## Error Code System
Error codes follow a hierarchical system:
- **1000-1999**: Authentication & Authorization errors
- **2000-2999**: Validation errors
- **3000-3999**: Resource errors (not found, conflict, etc.)
- **4000-4999**: Business logic errors
- **5000-5099**: Rate limiting errors
- **6000-6999**: External service errors
- **9000-9999**: Internal server errors
## Changes Made
### Backend Changes
1. **`internal/middleware/error_handler.go`**:
- Updated to use `APIResponse` envelope
- All error responses now include `success: false`
- Standardized error object structure
- Added timestamp to all error responses
2. **`internal/handlers/webhook_handlers.go`**:
- Replaced all `gin.H{"error": ...}` with `RespondWithAppError`
- Consistent error handling across all webhook endpoints
- Proper error codes and messages
3. **Error Response Helpers**:
- `RespondWithAppError`: Main function for standardized errors
- `RespondWithError`: Alternative for simple errors
- Both use `APIResponse` envelope
### Frontend Compatibility
The frontend already supports the standardized format:
- `parseApiError` handles `{success: false, error: {...}}` format
- `ApiError` type matches backend structure
- Error messages displayed correctly to users
## Testing
All error responses should:
1. Use `APIResponse` envelope with `success: false`
2. Include all required error fields (code, message, timestamp)
3. Include optional fields when available (request_id, details, context)
4. Use appropriate HTTP status codes
5. Be parseable by frontend `parseApiError` function
## Migration Notes
- Legacy error formats (`gin.H{"error": ...}`) have been replaced
- All handlers now use `RespondWithAppError`
- Middleware ensures unhandled errors are standardized
- Frontend handles both old and new formats for backward compatibility
## Files Modified
- `veza-backend-api/internal/middleware/error_handler.go`
- `veza-backend-api/internal/handlers/webhook_handlers.go`
- Created: `ERROR_RESPONSE_STANDARD.md` (this document)
## Next Steps
1. ✅ Standardize middleware error handler
2. ✅ Update webhook handlers
3. ✅ Verify frontend compatibility
4. ⏳ Audit other handlers for non-standard error responses
5. ⏳ Add integration tests for error format validation
