Shopify Discount Code

[devsunwayuser]

Hi,
I'm trying to create discount code that applies for seal subscription and that discount code should support subscription.  I had added this in price rule: "appliesOnSubscription": True, but it didn't work. Neither it's throwing error nor it's doing it. Every time the discount code is created with purchase type of one-time purchase. How can i make it happen?  It would be helpful if anyone can provide me full docs or full code to create discount code that supports both.
