Common Errors & Troubleshooting

Receiving HTML instead of JSON Missing Accept: application/json header
✓ Add -H 'Accept: application/json' to your curl command or set the Accept header in your HTTP client
404 Not Found Incorrect URL path or missing required name parameters
✓ Check the FOAAS documentation at foaas.com for the correct endpoint path; most endpoints require a name and from parameter in the URL
CORS error in browser FOAAS may restrict cross-origin requests from certain origins
✓ Use the API from a server-side environment or a backend proxy rather than directly from a browser frontend
