Has anyone written a script to accomplish this?
As we ramp up our development for subscriptions, we'd love to hear about your subscription use cases to better align our features with your needs. If you're planning on using subscriptions in your Knack app we would appreciate it if you could fill out this short survey: https://www.knack.com/knackstars#subscriptions-survey/
And if you haven't done so yet, sign up for the Knackstars program so you can join the beta when it's ready: https://www.knack.com/knackstars#register/
Hi Justin, I'm already aware of these plans, thanks! I ended up writing a custom implementation of this. However, the creation of new 'charge' records ended up being done on my own server with a PHP script, since I don't have server-side access to Knack.
If you can wait -Knack is rolling this feature out -probably later in the year. Their public roadmap shows it's currently in active development.
