Troubleshooting
"API key is required"
You have Demo Mode turned off but didn't provide an API key. Either:
- Turn Demo Mode on to test with sample data
- Add your API key in the input
"API error 403" or "Unauthorized"
Your API key is invalid, expired, or doesn't have access to this specific API endpoint. Double-check your key and account permissions.
"API error 429" or "Rate limit"
Too many requests. Wait a minute and try again, or reduce the number of items per run.
No results or empty dataset
Check the run log for error messages. Common causes:
- Invalid input format (check the examples above)
- API key without proper permissions
- The target data doesn't exist or is too small to track
How do I test without an API key?
Enable Demo Mode in the input. This returns realistic sample data so you can verify the output format works for your workflow.
