All Buena.ai API requests require authentication using user-specific API keys. Each key has granular permissions and tracks usage for security and billing purposes.

​
API Key Format

Buena.ai supports two types of API keys for maximum flexibility and backward compatibility: Format: bna_[hexadecimal] where the hexadecimal string is 64 characters long: 
bna_bxxxxxxxxxx
Benefits:
  • Automatic User Detection: No need to specify user IDs in requests
  • Enhanced Security: User-specific permissions and rate limiting
  • Better Tracking: Automatic usage tracking and last-used timestamps
  • Granular Permissions: Support for specific permission scopes

​
Global API Keys (Legacy)

Format: Traditional API key format for backward compatibility: 
abc12345-xyz789def456ghi123jkl
Characteristics:
  • Full Access: All permissions (*)
  • Legacy Support: Works with all existing endpoints
  • Requires User IDs: Must specify user IDs in request parameters
  • Backward Compatible: Maintains compatibility with v1 API patterns

​
Authentication Header

Include your API key in the x-api-key header for all requests: 
curl -H "x-api-key: YOUR_API_KEY" \
     -H "Content-Type: application/json" \
     "https://api.buena.ai/api/v2/health"
Never expose your API key in client-side code, public repositories, or logs. Always use environment variables or secure secret management.

​
Permission System

Each API key has specific permissions that control access to different endpoints. User-specific API keys support granular permissions, while global API keys have all permissions (*).

  "message": "Insufficient permissions",
  "version": "2.0",
  "permissionHelp": {
    "required": "linkedin:schedule",
    "available": ["linkedin:read"],
    "documentation": "https://docs.buena.ai/authentication"
  }
}
Causes:
  • API key lacks required permission
  • Attempting to access restricted endpoint

​
Testing Authentication

Use the health endpoint to verify your authentication: 
curl -H "x-api-key: YOUR_API_KEY" \
     "https://api.buena.ai/api/v2/health"
Successful response: 
{
  "version": "2.0",
  "status": "healthy",
  "authentication": "user",
  "user": {
    "id": "user_abc123",
    "email": "john@company.com",
    "role": "Premium"
  },
  "apiKey": {
    "name": "My Integration Key",
    "permissions": ["linkedin:schedule", "leads:read"],
    "usageCount": 42
  }
}
