API Authentication
How to generate and use Castor Flow API keys.
The Castor Flow API uses API keys for authentication. All requests must include your API key in the Authorization header.
Generating an API key
- Go to Settings → API
- Click "Generate New Key"
- Give the key a name (e.g. "Production" or "Zapier")
- Copy the key — it is only shown once
⚠️ Warning
Store your API key securely. Anyone with your key has full access to your Castor Flow account. If a key is compromised, revoke it immediately and generate a new one.
Using the key
Include the API key in the Authorization header of every request:
Authorization: Bearer YOUR_API_KEYKey permissions
All keys have full access to your account data. Scoped keys (read-only, specific resources) are on the roadmap.
