The FTP Polling service is used to check the arrival or modification of a file(s) on a FTP location.

Steps to create a FTP polling activity:

1. Click Configure > POLLING > FTP.

2. Click Create FTP Polling.
   
   
   
   

3. On the Create FTP Polling window, enter the name and description of the new FTP Polling Service service in the Name and Description fields.

5. Enter the username and password required to access FTP Server in the User ID and Password fields.
6. Re-enter the password in the textbox Confirm Password.
7. Select the transfer type as either Active or Passive from the drop-down list of Transfer Type. 
   1. ACTIVE transfer is more secure since the client only initiates communication to the Server on one port.
   2. PASSIVE transfer the client initiates communication to the Server over two ports. Passive mode is useful when you are behind a firewall or a proxy.

8. Select the trigger from the Trigger Type drop-down list. 

   On FileModified	To configure the FTP Polling service to check for any modification in the file(s).

9. Select SFTP checkbox if the FTP Server specified in the Host Name is an FTP Server over SSL.
10. Select the key manager from the Key Manager drop-down list.

11. Select FTPS checkbox if the FTP Server specified in the Host Name is an FTP Server over TLS/SSL.  

    1. Select the mode from the FTPS Mode drop-down list. It can be Explicit or Implicit depending on FTP Server you are accessing. 

    2. Select the protection level supported by the FTP Server from the Protection Level drop-down list. This drop-down list has the following three options: 

       • None
       • Clear
       • Private

       By default, the option None is selected.

    3. Select Validate Server checkbox to validate the certificate sent by the FTPS Server against the certificate imported in Keystore.

    4. Select the activity from the Keystore Name drop-down list. This option is applicable only if you have selected Validate Server.
       
       

       Info
       When Validate option is unchecked, it always accepts the certificate sent by FTPS Server. When this option is checked, it validates the certificate sent by FTPS server against the certificate imported in Keystore.

       
       

12. Enter the name of file that FTP Polling service needs to verify in the File Include Criteria field.
13. Enter the name of the file that the FTP Polling service does not need to verify in the File Exclude Criteria.
    
    For example, you have typed *.txt as a value in the File Include Criteria, and you want following two files Gdata.txt and Gdata1.txt file not to be verified by the FTP Polling Service, then Gdata.txt and Gdata1.txt file name need to be entered separated by a comma in the File Exclude Criteria. You can also use regular expressions to specify more than one file in the File Include Criteria and File Exclude Criteria.

14. Enter the path of file in the File Base Location. Example c:/Gmdata.

    You can also use regular expression for folders in File Include Criteria and File Exclude Criteria fields. For example, if you enter h*/*.txt in File Include Criteria field and C:/Gmdata in File Base Location field, it will search for all .txt file inside all directories which starts from h under C:\Gmdata.

15. Enter the time interval, the FTP Polling Service will check for the arrival of any file or modification of existing file in the Polling Frequency field. Enter digit in the Frequency field and select the unit of time i.e. seconds, minutes or hours etc. from the dropdown list Duration.

    Info
    We recommended minimum Polling Frequency to be more than 60 seconds.

    
    

16. Enter the file stable time in the File Stable Time field. This is applicable only when user selects On FileModified in trigger type. Polling will wait for the above specified time to become a file stable.

17. Enter the expiry time in the Expiry Time field. After expiry time process flow does not poll for the file.

    When a FTP polling service is used in a process flow, it creates a Polling Status activity variable. For more information, refer to Polling Status.
