FTP Receive Endpoint Settings

FTP receive endpoints determine where to receive B2B messages transmitted over FTP. There are two types of FTP endpoints:

  • Receive from Partners

    Source endpoint in an inbound message flow that receives B2B messages from partners either directly or via third-party connections.

    A host, partner, or third-party connection can own FTP Receive from Partners endpoints.

  • Source at Host

    Source endpoint in an outbound message flow that receives messages from the backend applications.

    Only a host can own FTP Source at Host endpoints.

Create FTP receive endpoints by configuring these settings on the <host> or Partner pages. You can also create these endpoints when you configure an outbound message flow:

Name Description Required

Endpoint Name

Automatically generated name used to identify the endpoint, which you can modify manually.



Host, partner, or third-party connection that owns the endpoint.



Protocol that the endpoint supports.



User-supplied value that describes the purpose of the endpoint.


FTP server host, such as ftp.mulesoft.com, localhost, or The host must be accessible from your Mule environment.



Port number of the FTP server.



Username for connecting to the FTP server.

x (if the server is authenticated)


Password for the FTP server.

x (if the server is authenticated)

Source path

Path on the FTP server to which the partner or third-party connection sends the inbound files.


Polling Frequency

Frequency with which the server checks the source path for new files. The default is 1 minute.


Supported Format Types

Applies only to FTP endpoints owned by partners or third-party connections. Indicates whether the endpoint supports EDI messages (EDIFACT, X12) or non-EDI messages (JSON, XML).


Size check wait time

Wait time, in seconds, between size checks to determine if a file is ready for processing. The default of 1 second enables a file write to finish before processing the file.

Mule performs two size checks by waiting the amount of time specified in this field. If both checks return the same value, the file is ready to process.

To disable this feature, specify a negative number or omit the value.


File name pattern

Filename pattern required by your partner.

Archival Path

FTP server path at which to store a copy of the file obtained from the source path.
