@mark_wymer I thought it was you 😀!! Yeah not bad thanks, still here 😉 Yes, you have it correct; write the file to the OS, add to the vault then use the vault_id to attach, or add to a list of vault_ids to attach. When you add to the vault it will be added to a separate location on the OS that is under vault control. I'm not 100% sure if the file deletes when you add to the vault, however, you can delete the file if you wish but if it's in a "true" tmp directory then it will get flushed on reboot but if there is a chance there will be a lot of this activity it might be best to put something in place to clear the tmp directory, outside of a reboot, more regularly?
