Zynk Workflow Documentation

The FTP Repeater task will allow you to run a series of sub-tasks against all the files in the directory on the remote server. This tutorial will show you how to use the context variables within the repeater, and to download and remove files fromthe remote server.  You can download the sample workflow here,or build the workflow manually using the instructions below.

The repeater could be used if you have a system that outputs data to an FTP site e.g. new orders are written out in XML format.  Zynk can list all the files in the directory, and for each of files run any required sub-tasks e.g. download the file and import into another system.

To use the sample workflow you will need to have access to an FTP server, and have the required credentials to hand.  Edit the workflow variables, and set your details for FTP_SERVER, FTP_USERNAMEFTP_PASSWORD and FTP_DIRECTORY.

The first task in the repeater will list all the context variables available to the sub-tasks, it will write a line out for each file found in the directory.  Using the example of download orders from a site, the second and third tasks in the repeater (you will have to enable these) will download any files as orders.xml, and remove the file from the FTP site.  Note enabling the delete task will remove files stored on  your FTP site, make sure you are using this on a test environment.
