Coupon option not available on Braintree Jotform integration.

I am trying to get a coupon option to appear for the Braintree Jotform integration.

It is an option for products, but not for subscriptions.

Note: I have created a coupon inside Braintree for the 1st subscription option....but it not appearing as an option on the form to select...

I have been checking this and I can see what you're reporting; however, seems like Braintree subscriptions do not support coupon codes so far. Coupons feature are not available through the API, it is a feature only available through the Braintree dashboard. 

In case it comes available, our developers will implement it on the current integration.
