Error Handling and Troubleshooting

Encountering errors is a natural part of API integration. This guide helps you understand common error responses from the Document Summarization API, interpret error messages, and implement strategies to resolve issues effectively.

• Common Error Responses

  The API may return various HTTP status codes to indicate the outcome of your requests. Understanding these codes helps in diagnosing and fixing issues.

  • 400 Bad Request:

    Indicates that the request was malformed or contained invalid parameters.

    Example Response:

    jsonCopy code{ "error": "Invalid 'tone' value. Allowed values are: energetic, neutral, calm, formal, informal.", "success": false, "completion_time": 500 }

  • 401 Unauthorized:

    Occurs when the subscription key is missing, invalid, or expired.

    Example Response:

    jsonCopy code{ "error": "Invalid subscription key.", "success": false, "completion_time": 400 }

  • 403 Forbidden:

    The request is understood, but it has been refused or access is not allowed.

    Example Response:

    jsonCopy code{ "error": "Access denied for the requested resource.", "success": false, "completion_time": 450 }

  • 404 Not Found:

    The requested resource could not be found.

    Example Response:

    jsonCopy code{ "error": "The requested endpoint does not exist.", "success": false, "completion_time": 300 }

  • 429 Too Many Requests:

    Indicates that you've exceeded the API's rate limits.

    Example Response:

    jsonCopy code{ "error": "Rate limit exceeded. Please try again later.", "success": false, "completion_time": 100 }

  • 500 Internal Server Error:

    An unexpected error occurred on the server side.

    Example Response:

    jsonCopy code{ "error": "An error occurred while processing your request.", "success": false, "completion_time": 1500 }

• Error Message Explanations

  • Invalid Parameters:

    Errors like Invalid 'tone' value suggest that a parameter value does not match the allowed options. Review your request payload to ensure all parameters use valid values.

  • Authentication Errors:

    Invalid subscription key or Access denied errors indicate issues with your API key. Ensure that you're using the correct key and that it hasn't expired or been revoked.

  • Rate Limiting:

    Exceeding the number of allowed requests within a given timeframe triggers 429 Too Many Requests. Implement retries with exponential backoff to handle such scenarios gracefully.

  • Server Errors:

    500 Internal Server Error points to issues on the API's end. In such cases, retrying the request after some time or contacting support may be necessary.

• Debugging Failed Requests

  • Check Request Payload:

    Ensure that your JSON payload is correctly formatted and includes all required parameters with valid values.

  • Verify Subscription Key:

    Confirm that you're using the correct subscription key and that it is included in the request headers.

  • Inspect API Endpoint:

    Make sure you're sending the request to the correct API endpoint and using the appropriate HTTP method.

  • Monitor Rate Limits:

    Keep track of your API usage to avoid exceeding rate limits. Adjust your application's request frequency as needed.

  • Review API Documentation:

    Refer to the API's official documentation for detailed information on parameters, responses, and error codes.

• Best Practices for Robust Error Handling

  • Implement Retry Logic:

    For transient errors like 500 Internal Server Error or 429 Too Many Requests, implement retries with exponential backoff to handle temporary issues.

  • Validate Inputs Before Sending:

    Ensure all request parameters meet the API's requirements to minimize the likelihood of 400 Bad Request errors.

  • Use Logging:

    Log all API requests and responses, including error details, to aid in debugging and monitoring.

  • Provide User Feedback:

    Inform users gracefully when errors occur, and, if possible, provide actionable steps or alternative options.

  • Secure Error Information:

    Avoid exposing sensitive information from error responses to end-users. Use generic messages and handle specifics within your application logic.
