Platform
An overview of the core entities and unique concepts that form the foundation of the Fusio API management platform.
Operation
The entry point of your API. It maps an HTTP method and path to an Action while enforcing data integrity via Schemas.
Action
The execution layer for your business logic. Connect to databases, external APIs, or run custom scripts in PHP, JavaScript, or Python.
Schema
Defining the shape of your data. Based on TypeSchema, these models ensure that every request and response is perfectly structured.
Connection
The bridge to your infrastructure. Define how to reach external services like SQL databases, remote HTTP APIs or AI agents. Connections are resolved into fully configured clients for your actions.
Event
The heartbeat of asynchronous workflows. Actions emit named occurrences (e.g., order_placed) that allow external systems to subscribe via webhooks.
Cronjob
Automated maintenance and batch processing. Schedule any Action to run at regular intervals, be it every minute, hour, or specific day of the week.
Trigger
The glue of event-driven architecture. Triggers listen for specific Events and immediately execute a configured Action, like sending an email when a user registers.
Conceptual Architecture
A visual blueprint of the Fusio core.
AI Agents:
Internal & External
Fusio bridges the gap between raw LLM power and secure execution. It acts as a controlled environment where AI can interact with your business logic without bypassing security layers.
Assist developers in generating actions, schemas, and configurations within the Fusio backend.
Empower your users to build custom tools using your API operations as LLM-ready functions.
Polyglot Development
Build logic in your language of choice. Fusio's worker system handles the execution while providing seamless access to all your connections.
Marketplace
Share and install entities directly from the community. A thriving hub for actions, schemas, and bundles.
Unified Protocols
Type-Safe SDKs
Automated code generation for client/server harmony.
