Poor documentation around modifying a PHLO with python

[bangejsans]

I wish to programmatically update the number I'm forwarding calls and texts to (to rotate an on-call shift).

I am trying to use the PHLO api to get the relevant nodes and update the recipient, however, getting a node in a PHLO requires a node_type and node_id. Nowhere can I find what a valid node_type is, and I am assuming the node_id is the name of the node, but again, I can't find documentation supporting this.
