Errors

The Capital Check In API uses conventional HTTP response codes to indicate the success or failure of an API request.

​
HTTP Status Codes

CodeDescription
200OK - Request successful
201Created - Resource created successfully
400Bad Request - Invalid request syntax
401Unauthorized - Authentication required
403Forbidden - Insufficient permissions
404Not Found - Resource not found
422Unprocessable Entity - Validation error
429Too Many Requests - Rate limit exceeded

​
Error Response Format

All error responses follow a consistent format: 
{
  "error": "error_code",
  "message": "Human-readable error message",
  "details": {
    "field": "Additional error details"
  }
}

​

Error Handling Best Practices

  • Always check the HTTP status code first
  • Parse the error response for detailed information
  • Implement proper error logging
  • Handle rate limiting with exponential backoff
  • Provide user-friendly error messages
  • Retry transient errors (5xx status codes)
