Will need to also add a DistributedMapCacheServer Controller service that above client will talk to.&nbsp; This will make sure each node grabs password and stores it locally on that nodes's DMCServer)<BR /><BR />Then in your flow using putSFTP, you would replace the invokeHTTP processor a fetchDistributedMapCache processor just before the putSftp processor (suggest looping failure relationship from putSFTP back to fetchDistributedMapCache processor&nbsp; just in case password changes or there was no password stored when fetch was attempted first time).<BR /><BR />Keep in mind that flows like this are not idea.&nbsp; The retrieved password that you are placing in to a FlowFile attribute is stored in plaintext.<BR /><BR />If you found this solution helpful, please take a moment to login and click accept on this solution.<BR />Good luck,</P><P>Matt</P> Wed, 05 May 2021 13:10:39 GMT MattWho 2021-05-05T13:10:39Z
