# ftp\_session

Establishes a connection to an FTP or SFTP server. All FTP operations (`ftp_list`, `ftp_download`, `ftp_upload`, `ftp_move`, `ftp_delete`) must be placed inside this block.

```liquid
{% ftp_session host: "ftp.example.com", user: "username", password: "password" %}
  {% ftp_list path: "/data" as files %}
  {% log files %}
{% endftp_session %}
```

#### Syntax

```liquid
{% ftp_session host: "hostname", user: "username", password: "password" %}
  ... FTP operations ...
{% endftp_session %}
```

  {% ftp_list path: "/" as result %}
  {% log result.files %}
{% endftp_session %}
```

**SFTP connection:**

```liquid
{% ftp_session host: "sftp.example.com", user: "myuser", password: "mypass", sftp: true %}
  {% ftp_download from: "/exports/data.csv" as result %}
  {% log result %}
{% endftp_session %}
```

**Custom port:**

```liquid
{% ftp_session host: "ftp.example.com", user: "myuser", password: "mypass", port: 2121 %}
  {% ftp_list path: "/files" as result %}
{% endftp_session %}
```

**Using variables for credentials:**

```liquid
{% ftp_session host: FTP_HOST, user: FTP_USER, password: FTP_PASSWORD, sftp: FTP_SFTP %}
  {% ftp_list path: FTP_PATH as result %}
  {% for file in result.files %}
    {% log file.name %}
  {% endfor %}

* Connection is automatically closed when the block ends
* All FTP operation tags must be nested inside `ftp_session`
* Supports both FTP (port 21) and SFTP (port 22)
* Connection timeout is 5 minutes by default
* Each FTP operation inside the session consumes 2 credits
