You would not need to send any input to a node, but rather you would need to send the input to a specific process instance which is waiting for that input on a node. So the external system needs to know the id or the instance that is waiting. (Or any qualifier that would find one or more processes, i.e. any process where Company Name = 'Dutch Beer Co'.)
If you were going to send a message out to the external system informing it that your workflow is ready for some input, you could pass some kind of instance ID in the message and have the external system send it back with their input. Your processing logic then becomes something like
1. parse id
2. get instance
3. parse input
4. signal instance with input
partly correct, and by magic, dutch beer makes it to the stage again :-)
If there are multiple tokens, it could be that you need to signal a specific token and not the process in general. In that case you do need to eventually refer to a token ID, either directly, or by e.g. passing a node name and looking up the token or whatever.
