API Troubleshooting Nexus

Understanding Common Error Codes

API errors are typically categorized by HTTP status codes. Familiarizing yourself with these codes is the first step to effective troubleshooting.

• 400 Bad Request: The server could not understand your request due to invalid syntax or parameters.
• 401 Unauthorized: Authentication credentials are missing or invalid. Ensure your API keys or tokens are correctly included.
• 403 Forbidden: You have valid credentials, but your account does not have permission to perform the requested action.
• 404 Not Found: The requested resource (e.g., an endpoint or an ID) does not exist. Double-check the URL and any resource identifiers.
• 500 Internal Server Error: A generic error message indicating something went wrong on the server side. This often requires us to investigate.
• 503 Service Unavailable: The server is temporarily unable to handle the request, often due to maintenance or overload.

Request Formatting and Authentication

Incorrect request formatting or authentication can lead to a variety of errors. Pay close attention to the structure of your requests.

Example of a Valid GET Request:

GET /api/v1/users/12345 HTTP/1.1
Host: api.example.com
Authorization: Bearer YOUR_ACCESS_TOKEN
Accept: application/json

Ensure your Authorization header is present and correctly formatted with your API key or token. Check that the HTTP method (GET, POST, PUT, DELETE) matches the endpoint's requirements.

Response Analysis

The API's response body often contains valuable information about the error, even if the status code is generic. Always inspect the response payload.

Example Error Response Body:

{
    "error": {
        "code": "INVALID_PARAMETER",
        "message": "The 'user_id' parameter is missing or malformed."
    }
}

Look for a dedicated error object or similar structure that details the specific reason for the failure.

Rate Limiting and Usage Limits

To ensure fair usage and system stability, our API enforces rate limits. Exceeding these limits will result in a 429 Too Many Requests error. Monitor your request frequency and implement backoff strategies if you encounter this.
