# SFTP Trigger - Workflow trigger | Docs - nodulz

Source: https://nodulz.com/docs/nodes/sftp_trigger

Language: en

Poll a directory for SFTP file changes.

## Usage and specifics

FTP uses an FTP credential; SFTP uses an SSH credential. Check remote paths and permissions before writing or deleting. Triggers poll files after publishing; interval and filters determine detected events.

Technical type : `sftp_trigger`. Runtime : `nodulz`.

## Credentials and prerequisites

- [Create and configure the credential : ssh](/docs/credentials/ssh)

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the [credentials guide](/docs/credentials) for access and rotation.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `credentialId` | `string` | `""` | - |
| `path` | `string` | `"."` | - |
| `events` | `array` | `["created"]` | -; min 1 |
| `pollInterval` | `number` | `60` | -; ≥ 10, ≤ 86400 |
| `testPayload` | `string` | `""` | - |

## Configuration help

| Setting | Purpose and guidance |
| --- | --- |
| `events`<br>Events | File creation, modification or deletion. Changes are detected by remote size or modification time, without comparing content. |
| `pollInterval`<br>Interval (seconds) | Between 10 and 86,400 seconds. Changes between scans may be missed. Limit: 10,000 entries or 5 MiB per directory. |
| `testPayload`<br>Test data (JSON) | Optional JSON object for manual tests, without connecting to the server. Leave empty for generated sample data. |

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "credentialId": "",
  "path": ".",
  "events": [
    "created"
  ],
  "pollInterval": 60,
  "testPayload": ""
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
