To query the lines stored in the system via the API of the Travelmanager booking software, you can use the following URL:
`xml.php?token=xyz&aktion=getLinien`
This query returns all relevant information about the lines and tours. The result is a JSON array containing the list of lines.
Example for the return:
```json
[
{
"line_id": "1",
"name": "line 1",
"description": "Description of line 1"
},
{
"line_id": "2",
"name": "Line 2",
"description": "Description of line 2"
}
]
```
Use this information to process the lines and tours in your system.
