List integration catalog

Retrieve the catalog of available third-party integrations.

Returns a comprehensive list of all integration providers supported by SuperAI Flows. Each integration includes metadata about authentication requirements, capabilities, and categorization to help users discover and connect external services to their workflows.

Context: - The integration catalog is the primary discovery mechanism for available services - Dynamically generated from the plugin registry (no database storage overhead) - All authenticated users can access the catalog - Automatically excludes credentialless integrations and integrations in migration

Integration Categories: - database: PostgreSQL, internal PostgreSQL database connectors - storage: SharePoint document libraries, SFTP file servers - messaging: AWS SES email integration - automation: Various task executors and workflow automation tools

Authentication Methods: - oauth2: OAuth 2.0 authorization flow (Google, SharePoint, Microsoft) - user_password: Username/password authentication (SFTP, PostgreSQL) - api_key: API key-based authentication - key_file: SSH key-based authentication (SFTP)

Use Cases: - Display available integrations in UI marketplace - Show available connectors during flow task configuration - Validate provider support before connection attempts - Determine authentication requirements before OAuth flows - Populate provider selection dropdowns

Related Endpoints: - GET /integrations/plugins - List detailed plugin metadata - GET /integrations/plugins/{plugin_name}/capabilities - Get plugin capabilities - POST /integrations/credentials - Create credentials for integration - GET /integrations/credentials - List user's configured credentials

Notes: - OAuth integrations require additional authorize/callback flow - Integration availability ≠ user has configured credentials - Plugin system allows custom integrations without code changes - Use GET /integrations/credentials to check user's connections
