# Import/Export

In this context, Import / Export refers to:

* Exporting reusable assets (flows, integrations, MCP servers, auth blocks) from one file or module
* Importing those assets into another file or project
* Treating YAML config as modular, composable building blocks

YFlow files can be imported into Customer v2 and exported for external editing or version control.

#### Import Flow

An Import Flow allows one flow to reuse, include, or invoke another flow that is defined elsewhere (often in another file or module).

Import Flow = reuse an entire conversation flow as a building block

Instead of duplicating logic, you:

* Define a flow once
* Import it
* Invoke it where needed

```
    POST /api/flows/import    
    {    
      "yflow": "<yflow content>"    
    }    
```

#### Export Flow

An Export Flow is a flow that is explicitly made available for reuse outside the file or module in which it is defined.

Export Flow = publish a conversation flow as a reusable public capability

Only exported flows can be:

* Imported into other files
* Referenced by other teams
* Used as shared building blocks

```
GET /api/flows/{id}/export?format=yflow    
```
