API Call to Bulk Update Logins

I recently received an email from Oracle informing me that the "path" for API calls can no longer contain whitespace.

I checked and saw that several field resources have logins
with whitespace in the middle.

This will be a problem for us because we periodically deactivate users via API calls, but if the user has a whitespace in their name, the call will fail.

Therefore, I need a way to update all user logins with whitespace. Is there a way to do this? The "Update a resource" and "Update a user" calls didn't work.
