Error Handling

The API uses standard HTTP status codes and returns JSON error responses.

​
Error Response Format

{
  "error": {
    "code": "UNAUTHORIZED",
    "message": "Invalid or missing API key"
  }
}

​
HTTP Status Codes

CodeDescription
200Success
400Bad Request - Invalid parameters
401Unauthorized - Invalid or missing API key
403Forbidden - Insufficient permissions
404Not Found - Resource doesn’t exist
429Too Many Requests - Rate limit exceeded
500Internal Server Error

​
Common Error Codes

​
UNAUTHORIZED

{
  "error": {
    "code": "UNAUTHORIZED",
    "message": "Invalid or missing API key"
  }
}
Solution: Check that your API key is valid and included in the Authorization header.

​
INVALID_REQUEST

{
  "error": {
    "code": "INVALID_REQUEST",
    "message": "Missing required field: sessionExternalId"
  }
}
Solution: Check the request body includes all required fields.

​
NOT_FOUND

{
  "error": {
    "code": "NOT_FOUND",
    "message": "Session not found"
  }
}
Solution: Verify the session ID exists and belongs to your account.

​
RATE_LIMITED

{
  "error": {
    "code": "RATE_LIMITED",
    "message": "Rate limit exceeded. Retry after 60 seconds."
  }
}
Solution: Reduce request frequency or contact us for higher limits.

​
Handling Errors in Code

async function fetchSessions() {
  const response = await fetch("https://your-url.convex.site/api/sessions", {
    headers: {
      Authorization: `Bearer ${apiKey}`,
    },
  });

  if (!response.ok) {
    const error = await response.json();
    throw new Error(`API Error: ${error.error.code} - ${error.error.message}`);
  }

  return response.json();
}

​
Retry Strategy

For transient errors (5xx, rate limits), implement exponential backoff: 
async function fetchWithRetry(url, options, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    const response = await fetch(url, options);

    if (response.ok) return response.json();

    if (response.status === 429 || response.status >= 500) {
      const delay = Math.pow(2, i) * 1000;
      await new Promise((resolve) => setTimeout(resolve, delay));
      continue;
    }

    throw new Error(`Request failed: ${response.status}`);
  }
  throw new Error("Max retries exceeded");
}
