Forms API uses API-key authentication on protected endpoints:
  • X-API-Key: forms_sk_...

​
How to get an API key

  1. Sign in to the app.
  2. Go to Settings.
  3. Open the API Keys section.
  4. Click Generate to create a token.
  5. Copy and store it securely (the full key is only shown once).

​
API key authentication

Use API keys for server-to-server integrations and backend jobs. 
curl -X POST "https://api.sylvian.ai/parse" \
  -H "X-API-Key: forms_sk_your_key" \
  -F "file=@form.pdf"

​
Choosing between auth modes

  • Use API keys when your backend calls Forms API.
  • Do not expose API keys in frontend code.
Never expose API keys in browser code, public repos, screenshots, logs, or client-side analytics.
Treat API keys like passwords. Anyone with the key can call your API as your account.

​
Common auth failures

  • 401 Missing or invalid authentication: no valid API key was provided.
  • 401: API key format is wrong, inactive, or unknown.
