Subscription API gift note interpret a response.

[NicK323]

How to use the Shopify Subscription API or interpret a response to be able to pass a gift note created by a customer in the cart then pass that to the shopify order "notes" area?

Also, I want to know if this is possible with the subscription api:

Create a custom private app that will allow a future shipping start date for subscriptions. At the time of the order this app would schedule the future shipping date for the order.

thanks.
