LedgerBeam uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a request failed, etc.). Codes in the 5xx range indicate an error with LedgerBeam’s servers (these are rare).
CodeDescription
200 - OKEverything worked as expected.
400 - Bad RequestThe request was unacceptable, often due to missing a required parameter.
401 - UnauthorizedNo valid API key was provided.
402 - Request FailedThe parameters were valid but the request failed.
403 - ForbiddenThe API key doesn’t have permission to perform the request.
404 - Not FoundThe requested resource doesn’t exist.
409 - ConflictThe request conflicts with another request.
429 - Too Many RequestsToo many requests hit the API too quickly. We recommend an exponential backoff of your requests.
500, 502, 503, 504 - Server ErrorsSomething went wrong on LedgerBeam’s end. These are rare and if they happen, please contact us immediately.

​
Error Response Format

LedgerBeam uses two types of error response formats:

​
Field Validation Errors

When validation fails for specific fields: 
{
    "error": {
        "field_name": [
            "This field is required"
        ]
    }
}

​
General Errors

For authentication and other general errors: 
{
    "error": "Unauthorized access"
}

​
Common Error Scenarios

​
Missing Required Field

{
    "error": {
        "field_name": [
            "This field is required"
        ]
    }
}

​
Unauthorized Access

{
    "error": "Unauthorized access"
}

​
Invalid API Key

{
    "error": "Invalid API key"
}

​
Best Practices

  • Handle 429 errors gracefully - Implement exponential backoff when you receive rate limit errors
  • Validate input data - Check your request parameters before sending to avoid 400 errors
  • Keep API keys secure - Ensure your API key is valid and has the necessary permissions
  • Monitor for 5xx errors - Contact support immediately if you encounter server errors
