Bash script to loop through remote directory and pipe files 1 at a time to CURL - bash

Question

I am trying to transfer all files residing in a specified directory on Server1 to Server3 via a script running on Server2.
The transfer to Server3 has to happen through an API and thus must use the following CURL call:
curl -X POST https://content.dropboxapi.com/2/files/upload \
--header "Authorization: Bearer $token" \
--header "Dropbox-API-Arg: {\"path\": \"/xfer/$name\",\"mode\": \"add\",\"autorename\": true,\"mute\": false,\"strict_conflict\": false}" \
--header "Content-Type: application/octet-stream" \
--data-binary #$f
If it is just 1 file, I can do it successfully, but i'm trying to iterate through the directory on Server1 and send the file directly to the CURL call. So far I've got:
files="( $(ssh me#server1 ls dir/*) )"
while read f
do
name=$(basename ${f})
curl -X POST https://content.dropboxapi.com/2/files/upload \
--header "Authorization: Bearer $token" \
--header "Dropbox-API-Arg: {\"path\": \"/xfer/$name\",\"mode\": \"add\",\"autorename\": true,\"mute\": false,\"strict_conflict\": false}" \
--header "Content-Type: application/octet-stream" \
--data-binary #$f
done <<< "$files"
The loop seems to be reading the "(" from the array of files into the 1st file name, which obviously causes a problem. I can't get beyond that to be able to tell if POSTING the current file in the loop via --data-binary will actually do what I think (or am hoping) it will.
Any ieas?

The error in the original message was enclosing the ssh command with "()". I am working on a similar issue. In the past I've used Rsync but I want a solution that doesn't require installing extra software. Here is an example that I'm working with to move files off of a Nodejs dev server to backup, running in Bash on Debian:
files=$(ssh chris#estack ls ~/tmp/gateway)
#echo $files
for FILE in $files
do
if [[ "$FILE" = "node_modules" || "$FILE" = ".git" ]]
then
echo "skip $FILE";
continue
fi
echo Copy ~/tmp/gateway/$FILE
#scp -Cpr chris#estack:~/tmp/gateway/$FILE ~/tmp/tmp
done
