Darkle About this, by recommendation of a guy from Stripe Discord I contacted Stripe API support and they answered me a few days ago, unfortunately they told me that for now there is no plan to include the Feature list through the API, it's something exclusive for the Stripe Pricing Tables and it will probably stay that way.
But they did tell me a solution that could be interesting, they say that you could get a very similar result using the Metadata of the product that is available through the API, so in this way you could structure the information about the features of the subscriptions, it could be something like this:
Key=Feature1 Value=Blabla
Key=Feature2 Value=Blabla
...
I don't know if you can repeat keys, I guess not (?) The cool thing is that this information can be easily retrieved through the API.
