Local Filesystem to Remote SFTP Server

The Local Filesystem to Remote SFTP Server is a Pipeline type used for a standard SFTP transfer scenario where UDMG acts as a client, pushing files from the local UDMG filesystem to an external SFTP server.

This Pipeline consists of:

Before You Begin

Prerequisites

Before configuring this Pipeline, we recommend you first:

  • Obtain your partner's SFTP Server connection details from their administrator, including hostname, port, and authentication credentials.
  • Identify your local source directory and ensure that UDMG has the necessary permissions to read files from it.
  • Test network connectivity to your partner's SFTP Server and manually verify that authentication succeeds.
  • Prepare API integration setup and have a UDMG User with domain-level permissions.

Understanding Paths in This Pipeline

When configuring a Local Filesystem to Remote SFTP Server Pipeline, several path fields determine where files are read from locally and where they are written to on the external SFTP server.

Each path has a specific role and is combined during runtime to build the complete source and destination paths used in transfers.

Paths Concatenation in Local Filesystem to Remote SFTP Server Pipelines

This path portion is determined by the security.domain_chroot argument defined in the Configuration File.

Valid security.domain_chroot values are:

  • NONE: No path is prepended.
  • WORKDIR: The file path is resolved relative to the work_directory_path argument defined in the Configuration File (e.g., /home/udmg/ or C:\UDMG\WorkDir\).
  • WORKDIR+DOMAIN: Same as WORKDIR, but UDMG also prepends the Domain name (e.g., /home/udmg/primary/ or C:\UDMG\WorkDir\primary\).

External SFTP Server Authentication

Pipelines where UDMG acts as a client—more specifically, those that contain a Remote SFTP Server Endpoint—require credentials to authenticate with the external SFTP server.

Unlike Pipelines, where UDMG acts as the server and relies on Accounts to supply credentials, these Pipelines define credentials directly within the Pipeline configuration.

This design enables each Pipeline to manage its own client authentication credentials independently. As a result, each Pipeline can only authenticate with one external system and use one distinct Credential Type at a time.

Supported Authentication Methods

UDMG supports three authentication methods when connecting to external SFTP servers. The external SFTP server configuration determines the required authentication method and must be provided by the server administrator.

info

Each Pipeline can only have one Credential Type associated with it at one time.

Transfer Scheduling via UDMG REST API

In a Local Filesystem to Remote SFTP Server Pipeline, each transfer must be explicitly scheduled through the UDMG REST API.

API Endpoint

POST /api/v1/domains/${UDMG_DOMAIN_NAME}/transfers/schedules

Request Body

The request body includes the following fields:

KeyDescriptionFormatRequired
pipelineName of the Pipeline associated with the transfer.Must match the Pipeline's Name field.Yes
scheduled

Date and time at which the file transfer is scheduled to be initiated.

If a past date is provided, the transfer is initiated during the next poll for pending transfers, based on the transfer.check_interval setting.

Must be in RFC 3339 format (2025-01-01T00:00:00Z).Yes
source

Optional filename and extension (plus optional path) to the source file.

For more information, refer to Understanding Paths.

  • "" (only if filename.ext is already specified in the Relative Path)
  • "/filename.ext"
  • "/dir/filename.ext"
  • "/dir/subdir/filename.ext"
Yes, unless filename.ext is already specified in the Relative Path
destination

Optional filename and extension (plus optional path) to the destination file. Can be used for renaming files.

For more information, refer to Understanding Paths.

  • "" (keeps the source filename and extension)
  • "/new_filename.ext"
  • "/dir/filename.ext"
  • "/new_dir/new_filename.ext"
  • "/dir/subdir/filename.ext"
  • "/new_dir/new_subdir/new_filename.ext"
No

Request Example

The following curl command schedules a file transfer using the Transfers Schedules Endpoint:

curl http://<UDMG_HOST>/api/v1/domains/${UDMG_DOMAIN_NAME}/transfers/schedules \
-X POST \
-H "Content-Type: application/json" \
-d '{
"pipeline": "Pipeline_Push",
"scheduled": "2026-07-03T15:43:52.344Z",
"source": "/Form1000.dat",
"destination": "/Received/Form1000.dat"
}'

Response Example

{
"scheduleId": 33,
"pipeline": "Pipeline_Push",
"username": "udmg.sys-admin",
"source": "C:\\UDMG\\WorkDir\\primary\\rootfilepath\\relativepath\\Form1000.dat",
"destination": "/Received/Form1000.dat",
"schedule": "2026-07-03T15:43:52.344Z",
"status": "Pending"
}

Check Transfer Status

Note that the response from the API only indicates that the transfer has been successfully scheduled, not that it has been completed. The transfer's status will be "Pending" until it is executed, at which point the status will update to "Completed" or "Failed" based on the outcome of the transfer.

After a transfer is scheduled, you can check its status by doing a GET request to the Transfers Schedules Endpoint, which returns a list of all scheduled transfers along with their current status.

GET /api/v1/domains/${UDMG_DOMAIN_NAME}/transfers/schedules

Adding a Pipeline
